METHOD FOR ADJUSTING THE TRANSMISSION OF PRINTING INK

Abstract

The invention relates to a method for adjusting the transfer of printing ink, wherein a first roller (54), which is arranged in an inker unit (42) of a printing machine, transfers printing ink to a form cylinder (43). A temperature control unit (57) enables the outer surface of the first roller (54) to reach the required temperature and/or a temperature control unit (58) enables the outer surface of the form cylinder (43) to reach the required temperature. Said temperature control unit (57) of the first roller (54) and/or the temperature control unit (58) of the form cylinder (43) can be, respectively, controlled or regulated by an adjusting device (37). specific curves or reference points for an interrelation between the production speed (V) of a printing machine and the respective required temperature on the outer surface of the form cylinder (43) or on the outer surface of the first roller (54) are stored in a storage unit (34) of the adjusting device (37) for various printing inks and/or ink types.

Description Method for Adjusting the Transmission of Printing Ink The invention pertains to a method for adjusting the transmission of printing ink according to the introductory part of claim 1. The document DE 694 02 737 T2 presents a temperature regulated system for printing machines, whereby a compression machine selectively offers tempering agents for tempering of inking rollers of several printing mechanisms for cooling as well as heating purposes. This takes place by means of selective feeding a heat exchanger with compressed tempering agent subsequently cooled in a condenser and finally de-stressed, and hence hot tempering agent. Either cooling or heating of a secondary tempering agent circulation now takes place in the heat exchanger. Temperature regulation takes place by means of dosage with this tempering agent on the basis of a temperature sensor and a regulating valve for each individual roller. The document DE 296 08 045 Ul shows a system for tempering, whereby for cooling the damping agent a first cooling unit with a first cooling process and a first fluid circulation is foreseen, which on the one hand is thermally coupled with the damping agent supply circulation of the damping agent through a heat exchanger, and on the other hand, thermally coupled with a second fluid circulation through a second heat exchanger, which on its part is thermally coupled with a cooling process designed as cooling tower. The document DE 44 26 083 Al presents a tempering device, where a tempering fluid can be guided for tempering a roller in its circulation, either through a heat exchanger in thermal contact with a cooling fluid circulation or even a heating heat exchanger. From the documents WO 03/045694 Al and WO 03/045695 Al we know about methods in which through tempering of a rotating component of a printing mechanism working together with the printing ink, an easy flow of the ink on the rotating component can be 2 kept largely constant in a temperature range of 22°C to 50°C, whereby the easy flow of ink depends on the temperature on the jacket surface of the rotating component and its production speed. This application is particularly found in waterless printing mechanisms, preferably in the printing mechanism for newspaper printing. The document EP 0 652 104 A1 reveals a printing mechanism for waterless offset printing with a regulating unit with several regulators, which for avoiding build-up of ink on a transmission cylinder of a printing mechanism regulate, depending on the fluctuation of a form cylinder of a printing mechanism allocated to the transmission cylinder or with a thermo-sensor on the transmission cylinder or an ink rolling cylinder of a inking mechanism allocated to the form cylinder, the determined temperature from a rated value with the help of a regulating valve for regulating a cooling agent fed to the respective cylinder, e.g. water. While printing, with the help of the regulated cooling agent quantity it should be possible to maintain a constant temperature of the print form arranged on the form cylinder, e.g. in a temperature range of 28°C to 30°C. The temperature of the transmission cylinder should be maintained at approx. 34°C to 35°C and the temperature of the inking mechanism between 25°C and 27°C. By feeding the cooling agent quantity there is also the possibility of pre-heating of the printing mechanism, so that cracking of the printing ink at the beginning of printing can be avoided on account of accumulation of paper particles in the printing mechanism, whereby a temperature flow of the cooling agent for pre-heating can be regulated according to a temperature-time-graph fed to the storage unit accommodated in the regulating unit. From the document DE 197 36 339 A1/B4 we know of a tempering device in a printing mechanism, whereby through tempering the rheological properties of the printing ink can be influenced, e.g. its viscosity or easy flow. The allied printing machine with a form cylinder has a short inking mechanism with an ink well, a screen roller and an inking roller. At least one of the inking mechanism rollers or the form cylinders can be tempered by the tempering unit. The tempering takes place by cooling or heating either from the jacket surface of the inking mechanism rollers or the form cylinder or in the interior of the inking mechanism rollers or the form cylinder. Additionally, also the ink 3 well can be tempered and particularly also the wipers for wiping excess ink from the screen rollers. The quantity of ink transmitted to the form cylinder can be regulated by means of a regulating cycle, whereby the optical density measured on the printing substance serves as signal parameter, on the basis of which the regulators allocated to the tempering unit regulate their temperature. The document DE-OS 19 53 590 presents a printing mechanism with an inking mechanism and a damping device that can be tempered with the help of a tempering unit. A rated value for the temperature can be determined in relationship to influence parameters, e.g. the printing speed, before starting of the printing process with the help of trial print, or can be set with the help of a table. An advantageous upper limit of the temperature of the printing ink is given with room temperature. From the document DE 39 04 854 Cl it is known that the rotation speed of the cylinder of the printing mechanism, the inking mechanism and the damping device have an influence on the inking mechanism temperature. In the document DE 44 31 188 Al a print form of a printing mechanism for waterless offset printing is cooled with the help of a cooling device to approx. 28 to 30°C. From the document DE 102 45 702 Al we know of a method for controlling the ink guiding in a machine processing print substances with at least one printing ink, where at least the physical properties of printing ink and/or print substances are known as data to a computer, whereby the stored data is read in a ink control model stored in the computer and on the basis of this ink control model the optimum settings with respect to ink guiding before commencement of printing or during the printing sequence can be taken up. It is the task of this invention to create a method for adjusting the transmission of printing ink. 4 This task is fulfilled according to the invention by means of the features given in claim 1. The advantages achieved through the invention are, on the one hand, that an adjustment and/or adaptation of the respective rated temperature on the jacket surface of the form cylinder or on the jacket surface of the first roller for different printing inks or ink types is possible for the operating personnel of a printing machine in a comfortable manner in a display and/or input mask on a monitor of an input and output unit of an adjusting device, because corresponding ink specific graphs or support points defining a correlation between a production speed of the printing machine and the respective rated temperature on the jacket surface of the form cylinder or the jacket surface of the first roller are stored in a storage unit of the adjusting device and can be displayed in the display mask and/or input mask, can be selected and altered. Besides it is advantageous that a conveying rate of a roller sourcing printing ink from a reservoir and transmitting it to an adjacent rotation body, for example a screen roller, is kept almost constant, so that on increasing the production speed of the printing machine in spite of a decrease in the capacity of the screen roller for transmitting printing ink as a result of an increasing incomplete emptying of its cups an almost uniform ink quantity is conveyed to the printing substance; and on the other hand, by adjusting the temperature on the jacket surface of particularly the formed cylinder in relation to the production speed of the printing machine, easy flow of the ink transported from the form cylinder can be maintained in a suitable range value-wise for the printing process, so that especially cracking of the ink on the surface of the printing substance can be avoided. The ink is adapted to the actual printing process in relationship to the production speed of the printing machine with respect to its fission capacity and adhesion capacity by appropriate adjustment of its temperature, whereby adjustment of its temperature indirectly takes place by adjusting the temperature on the jacket surface of a rotation body guiding this printing ink. In order to avoid wastage as a result of unsuitable temperature-dependent properties of the printed ink, in case of an intended alteration in production speed of the printing machine, the different time parameters for conducting the adaptation of temperature of the ink and for conducting the adaptation of the 5 production speed of the printing machine should be taken into account. There is also the possibility of manually altering a machine setting within certain limits and thus carrying out fine-tuning and of producing a good quality for the print product. All these measures contribute towards maintaining a high quality level of a print product produced with the printing machine in spite of alteration of the production speed of the printing machine. Design examples of the invention are shown in the drawing and are described in more details below. The following are shown: Fig. 1 A highly simplified depiction of four printing mechanisms of an offset rotor printing machine arranged in series; Fig.2 A schematic depiction of a printing mechanism for waterless offset printing; Fig. 3 A functional relationship between the production speed of the printing machine and a temperature to be adjusted on the rotation body guiding a printing ink on the jacket surface; Fig.4 A functional relationship between the production speed of a printing machine and an ink quantity to be conveyed by a screen roller; Fig. 5 A schematic depiction of different circulations of tempering agents in the printing machine; Fig. 6 An extract of a display mask and/or input mask for tempering the screen roller and form cylinder; Fig. 7 An extract of a display mask and/or input mask for selecting a certain printing ink; Fig. 8 A schematic depiction of the central readying and decentralised supply with tempering agent; Fig. 9 A detailed depiction of the supply unit; Fig. 10 A design for tempering a printing tower; Fig.l 1 A version for the design of a cold central unit; Fig. 12 A first design example for heat recovery; Fig. 13 A second design example for heat recovery; 6 Fig. 1 shows in a highly simplified depiction four printing mechanisms 01; 02; 03; 04 of an offset rotor printing machine arranged in series, respectively with a form cylinder 06; 07; 08; 09, a transmission cylinder 11; 12; 13; 14 and a counter pressure 16; 17; 18; 19, whereby for producing print product printed on both sides each counter pressure cylinder 16; 17; 18; 19 is preferably similarly designed as a transmission cylinder 16; 17; 18; 19, which again works together with a form cylinder allocated to it (not shown). A print carrier 21, e.g. a printed sheet 21 or a material web 21, preferably a paper web 21, is guided through during a production of the printing machine respectively between the transmission cylinder 11; 12; 13; 14 and the counter pressure cylinder 16; 17; 18; 19 and printed at least one printed image on it. It is insignificant for the invention whether the printing mechanisms 01; 02; 03; 04 are arranged in such a way that the print carrier 21 is guided horizontally or vertically through the printing machine. On the printing machine, preferably at the exit of the last printing mechanism 04 of the printing machine in transportation direction of the print carrier 21 an image sensor 22, e.g. a colour camera 22, preferably a digital semiconductor camera 22 with at least one CCD-chip, can be arranged with its image scanning region directly pointed on to the print carrier 21, whereby the image scanning region of the image sensor 22 captures the entire width of the print carrier 21, whereby the width of the print carrier 21 stretches transverse to its transportation direction through the printing machine. The image sensor 22 thus records an electronically usable image of the entire width of the printed paper web 21, whereby along the width of the paper web 21 at least one printed image is imposed on the print carrier 21. The image sensor 22 is designed for example as a flat camera 22. The image sensor 22 transmits the data correlated to the scanned image to a suitable evaluation unit 23, especially a programme-controlled electronic computing unit 23 that is arranged in a conducting stand belonging to the printing machine. Parameters relevant for the printing process can be controlled by analysing and evaluating the scanned image in the evaluation unit 23 and, if required, automatically corrected in a programme- controlled manner by programmes running in the evaluation unit 23. The evaluation and correction of all parameters of a printing process takes place practically simultaneously 7 with the help of the same evaluation unit 23. Particularly the image scanned by the image sensor 22 during a running production of a printing machine and passed on to the evaluation unit 23 in the form of data is evaluated to see whether the printed image scanned by the image and evaluated shows any change in tonality, especially an increase in tonality, with respect to the previously scanned and evaluated printed image, i.e. an actually scanned image is checked in the running printing process in comparison to a reference image. If the result of the text shows an alteration of tonality, i.e. generally a print-technically unavoidable increase in tonality, then the dosage and/or the feeding of ink in the printing machine is altered by a first setting command coming from the evaluation unit 23 and guided through a data line 24 to at least one of the printing mechanisms 01; 02; 03; 04, so that the tonality variation for a subsequent application of ink is minimum. After regulation of the ink density carried out by altering the dosage and/or the feed of printing ink, an image following the actually checked image conforms to a previously checked image of a printed image, i.e. to a reference image. Control and regulation of the tonality variation is important in order to maintain colour balance or grey balance in the printing process and to keep the colour impression of the produced print product as constant as possible - if required within permissible tolerance limits -, which constitute an important quality feature for print products. Similarly the data generated from the scanning of the printed image and transmitted to the evaluation unit 23 is taken for checking a registration consistency of the printed image impression on the print carrier 21, especially for checking and if required correcting a colour registration of a printed image printed in multiple colours. At least one motor- adjustable register is foreseen in the printing machine, e.g. a circumference register or a page register, if required even a diagonal adjustment for at least one of the form cylinders 06; 07; 08; 09 with respect to the transmission cylinder 11; 12; 13; 14 allocated to it, whereby the register is regulated by at least one second setting command coming from the evaluation unit 23 and forwarded through a data line 26 to at least one of the printing mechanism 01; 02; 03; 04, so that a printed image following the evaluated image gives the highest possible registration precision. An adjustment or shifting of the register is thus calculated by the evaluation unit 23 from the image data provided by the image 8 sensor 22 to the evaluation unit 23. By adjusting or shifting the page register even cross- expansion caused by fan-out can be countered, whereby this cross-expansion occurs especially in printing machine that have a so-called eight-tower structure for its printing mechanism. The printing machine is designed shaft-less. In such a printing machine the form cylinders 06; 07; 08; 09 have individual drives that are mechanically de-coupled from the drive of the counter pressure cylinders 16; 17; 18; 19, so that the phase position or the angle position of the form cylinders 06; 07; 08; 09 can be altered with respect to the counter pressure cylinders 16; 17; 18; 19 by a corresponding control or regulation of the drive of the form cylinders 06; 07; 08; 09, whenever an evaluation of the image scanned from the print carrier 21 by the image sensor 22 considers this to be necessary. The entire image content and not only individually locally limited image elements of the print carrier 21, e.g. reference mark or similar things, thus influences the control or regulation of the printing mechanism, especially the drive of a form cylinder 06; 07; 08; 09. A setting command generated by the evaluation unit 23 from the image content of the image scanned from the printed image acts on a control unit or regulating unit of a provision-regulated electrical motor for rotary drive during printing of at least one of the form cylinders 06; 07; 08; 09, the transmission cylinders 11; 12; 13; 14 allocated to it or counter pressure cylinders 16; 17; 18; 19. Thus at least one of the printing mechanisms 01; 02; 03; 04 of the printing machine the drive of the form cylinders 06; 07; 08; 09 or the transmission cylinders 11; 12; 13; 14 allocated to these form cylinders 06; 07; 08; 09 can be controlled or regulated by an electrical signal independent of the drive of the form cylinder 06; 07; 08; 09 or the transmission cylinder 11; 12; 13; 14 allocated to this form cylinder 06; 07; 08; 09 in anther printing mechanism 01; 02; 03; 04 of the printing machine; especially the mutual angle position or phase position of the form cylinders 06; 07; 08; 09 or their allocated transmission cylinders 11; 12; 13; 14 arranged in different printing mechanisms 01; 02; 03; 04 of the printing machine and involved in the printing of the print product, i.e. the printed image, can be adjusted to a registration suitable for production of a print product by the allied control unit or regulating unit, e.g. evaluation 9 unit 23. The electrical motor of a form cylinder 06; 07; 08; 09 is arranged co-axial to the axis of the form cylinder 06; 07; 08; 09, whereby the rotor of the motor is stiffly connected to its stud of the axis of the form cylinder 06; 07; 08; 09 in a manner as described for example in the document DE 43 22 744 Al. The counter pressure cylinder 16; 17; 18; 19 arranged in a different printing mechanism 01; 02; 03; 04 of the printing machine can, as described in EP 0 812 683 A1, mechanically be connected to one another by a train of gears and for example have a common drive, whereby however the form cylinder 06; 07; 08; 09 or the allocated transmitted cylinder 11; 12; 13; 14 remain de- coupled with respect to their drive from the counter pressure cylinders 16; 17; 18; 19 allocated to them. Between the form cylinder 06; 07; 08; 09 and the transmission cylinder 11; 12; 13; 14 allocated to it there can be a coupling by means of meshed gears, so that the form cylinder 06; 07; 08; 09 and the transmission cylinder 11; 12; 13; 14 allocated to it can be driven by the same drive. The control unit or the regulation unit of the drive of at least the form cylinders 06; 07; 08; 09 is for example integrated in the evaluation unit 23. Control or regulation of the phase position or the angle position of the form cylinder 06; 07; 08; 09 with respect to the counter pressure cylinders 16; 17; 18; 19 takes place with reference to a fixed reference setting, so that the form cylinder 06; 07; 08; 09 can have a leading or lagging rotation with respect to the counter pressure cylinder 16; 17; 18; 19 allocated to it, whereby the relation of the rotation of the form cylinder 06; 07; 08; 09 and the counter pressure cylinder 16; 17; 18; 19 allocated to it is adjusted in relation to the image content of the image scanned by the image sensor 22 and also followed up by the control unit or the regulating unit of their drives. Also the phase position or the angle position of successive form cylinders 06; 07; 08; 09 in the printing process can be controlled or regulated in the same manner with reference to a fixed reference setting, which is particularly important in multi-coloured printing of a print product printed colour-wise in successively arranged printing mechanisms 01; 02; 03; 04 of the printing machine. If from the image scanned from the printed image having several colours it is seen that a correction is required for an ink printed in one of the printing mechanisms 01; 10 02; 03; 04, then the evaluating unit 23 passes on the setting command to counter the determined disturbing influence on to the concerned printing mechanism 01; 02; 03; 04. If the adjusting drives to be regulated by the evaluation unit 23 by adjusting commands, e.g. the adjusting drive for regulating the feeding of printing ink as well as the drive for regulating the circumference register or the page register are connected in the printing machine to a data network connected to the evaluation unit 23, then the data line 24; 26 foreseen for transmitting the first and the second adjusting command is realised by the data network. Checking for tonality variation setting in the printing process and checking for registration consistency are carried out in the evaluation unit 23 simultaneously in data processing running in parallel branches simultaneously. Both the branches checks/tests are continuously conducted in the running process and that too at the end of the printing process and for each individual produced print sample. Checking for registration consistency initially referred to conformity in the position of a printed image or setting level between perfect printing and back printing or even between top side and bottom side in the production of both-sided print products. The check however also includes for example checking of the compass, i.e. checking the foreseen precision, individual path-colours in case of overprinting for multi-coloured printing. Registration precision and compass precision play a very important role in multi-coloured printing. A lighting device 27, e.g. a flash bulb 27, is allocated to the image sensor 22, whereby the short flash from the flash bulb 27 makes the fast running movement sequences in the printing process appear to be stand-still through a stroboscopic process and thus make them observable for the human eye. Especially in a sheet printing machine, scanning of the printed image executed by the image sensor 22 can also takes place in an extension 28 of the printing machine, that is shown in fig. 1 by a dashed depiction of the image sensor 22 and the allied lighting device 27 as a possible option for scanning the printed image 11 behind the last printing mechanism 04 of the concerned print page or is shown at the end of the printing machine. By capable choice of the image sensor 22 and if required the allied lighting device 23, scanning of the image can be extended or shifted to a visually not visible spectral range, e.g. the infrared or ultraviolet range. As an alternative to the preferred flat camera 22 with a flash bulb 27, it is also possible to use a cell camera with a permanent lighting. As each print sample is subjected to a test, in the running printing process a trend for tonality alteration or registration consistency of successively produced print samples can be identified. The print samples can be classified according to the value determined in the running printing process with respect to its tonality and/or its registration into groups of different quality stages and then marked as rejected sample if they cross a permissible tolerance limit. Rejected samples can be ejected in a controlled manner by the evaluation unit 23 and in the case of a sheet printing machine can be deposited in the extension 28 at least on a separate stack 29. For this purpose, from the evaluation unit 23 evaluating the image there is at least a third adjustment command guided through a data line 31, e.g. a wastage signal to at least one adjusting drive acting on at least one unit for transportation of the print carrier 21 for sorting the sample flow. For synchronizing the frequency with which detection of the images of the print carrier 21 takes place, with the transportation speed of the print carrier 21, i.e. the speed for example of the paper web 21, at least one of the print mechanisms 01; 02; 03; 04, preferably in the printing mechanism 01; 02; 03; 04 in which detection of the images by the image sensor 22 takes place, a rotation generator 32 is installed, whereby the running rotation generator 32 is at a fixed ratio to a rotation speed of the transmission cylinder 11; 12; 13; 14 on which the image sensor 22 scans the images. The rotation generator 32 gives its output signal to the evaluation unit 23 and/or also to the image sensor 22. The output signal of the rotation generator 32 is, among other things, used as releaser for the flash bulb 27. 12 The image scanned by the image sensor 22 and forwarded to the evaluation unit 23 in the form of a data set is displayed on a monitor of an input and output unit 33 connected to the evaluation unit 23 and having bi-directional data exchange. The input and output unit 33 similarly offers correction possibility for at least one of the mentioned regulations, in that it allows manual input and/or release of at least one adjusting command. The evaluation unit 23 has a memory 34 for storing scanned image sequences as well as storing data that are useful for protocol and thus for documenting the quality of the print product as well as for statistical analysis of the printing process. It would be advantageous if the evaluation unit 23 can make the data evaluated and/or stored image to a company network through a corresponding connection 36. For comparison of data carried out by the evaluation unit 23, which correlate the actually scanned image during a running production of a printing machine, with data of a previously generated image, it can be foreseen that the data of the previously generated image correlate with the image generated in a previous printing sequence of the printing machine, whereby a data processing unit of the printing pre-stage (not shown) is connected to the evaluation unit 23 and the data of the previously generated image is forwarded to the evaluation unit 23. In this way, data of the previously generated image are correlated alternatively or additionally to a data of the image scanned by the image sensor 22 and placed at the disposal of the evaluation unit 23 for evaluation. The data correlated to the printed image from the previous printing stage form low profile reference data for controlling and regulating the colour resistance with respect to data obtained from previously printed images in the running production. In the printing machine shown, a registration regulation and colour regulation is possible on the basis of analysis of the same image scanned in the printed image by the image sensor 23, in that the image of the printed image is evaluated with respect to various parameters relevant for the printing process in a single evaluation unit 23, as well as simultaneous inspection of the printed image for processing the quality of the print product. 13 The registration regulation is based on a registration measurement in the printed image. After all the colours required in the printed image have printed, the entire printed image is scanned by the camera at the end of the printing machine. In the evaluation unit 23 the scanned printed image is split up into the usual colour separations CMYK as used in printing technology, as well as an analysis of a suitable printed image segment and a relative position determination of a colour separation with respect to a colour separation by means of correlation method, with a previously scanned or obtained reference image. The reference image or reference value for image segment or a printed image mark (desired density) is drawn either from the previous printing step, which has the advantage that the reference image is available already in the individual colour segment, or a reference image, e.g. a reference sheet having the printed image, is taken for evaluation from an impression of the printed image, whereby this reference image has to additionally be split into the colour separations. This reference sheet is identified after the printed image is manually set in such a way, that all printed colours are positioned correctly with respect to one another and hence a proper colour registration is set. This thus obtained reference printed image is to be stored for later repetition jobs, so that for a repetition job one can fall back on this earlier scanned reference image. By accessing the stored reference printed image, the colour registration can be automatically adjusted by the evaluation unit 23 without manual intervention, which in case of a repetition job leads to further reduction in wastage. From the reference printed image, characteristics and suitable segments are selected, on the basis of which the positions of individual colour segments are determined as reference colour segments. This is the so-called desired position for later registration comparison. This reference image inclusive of colour segments and the desired position is stored for example in the storage 34. Selection of the suitable printed image segment can be done manually by the operator or automatically by the evaluation unit 23, e.g. for a pre-setting of the desired position. Suitable printed image segments with respect to registration measurements are regions, in which the printed ink to be measured dominates or appears exclusively. 14 In the continuous printing process, each printed image is scanned with the help of the camera system and split into the colour segments CMYK. Within the already fixed suitable printed image segment, the position of individual colour segment is now determined. This takes place by comparison with the colour segment from the reference printing image by means of a correlation method, particularly a cross-correlation method. With the help of the correlation method, the position of the colour segment can be determined up to approx. 0.1 pixel of the camera resolution. If for each printed sheet a stationary registration stage is determined repeatedly, then a higher precision of the measured value is ensured by suppressing stochastic dispersion. Determination of the position of the individual colour segments takes place in web run direction corresponding to the longitudinal registration and in cross direction to the web run direction corresponding to the page registration. The thus obtained position differences are converted by the evaluation unit 23 to setting command and sent as correction signal to the adjusting system, i.e. to the drives. In offset printing, special colours are not mixed with the standard colours, i.e. the scale colours CMYK, but are printed separately. Special colours are therefore not measured separately. Such the region in which the special colours are printed should be fixed. For each of the special colours, own suitable regions are fixed in which the position of the colour segment is determined in the same way as for the scale colours CMYK, i.e. the standard colours. The further procedure for registration regulation for special colour is identical to the procedure described already for standard colours. An advantageous design is described below, in which on the basis of the scanned data for colour density and/or spectral analysis, the regulation of the ink feeding is taken up by means of a temperature as guiding parameter that can be set on the jacket surface of the rotation body involved in the printing process. Determination of the data can thereby takes place through the entire web width or printing width, merely through one or more printed image segments or through special marks on the printing substance. The ink density corresponds to a layer thickness of the ink applied on the printing substance and 15 can be determined densito-metrically, and that too inline, i.e. in the running printing process, as well as offline, i.e. by means of a measurement on rejected print samples from the running printing process. As shown in fig. 2, an adjusting device 37 is foreseen, which is fed with a signal with data from the evaluation unit 23. For example, depending on the determined variation of an actually scanned ink density Dl from a pre-given desired value of the ink density D2 by the adjusting device 37, a variation of the temperature set on the jacket surface and determined by the adjusting device 37 with the help of one tempering unit 57; 58 of at least one of the rotation bodies 43; 47; 53; 54, e.g. cylinder 43; 47 or rollers 53; 54, involved in the printing process and transporting the ink, is taken up. With a view to quick, systematic and hence reproduce-able variation, in the storage 34 arranged in the adjusting device 37 or in the evaluation unit 23 a functional relation between a variation in ink density Dl and D2 and the temperature to be adjusted can be pre-retained, whereby this functional relation is graphically or electronically fixed in at least a graph, table or in any other suitable form representing the correlation. The adjusting unit 37 shown in Fig. 2 along with the arrows here represent the effective path of the control or regulation unit. Here no distinction has been made between signal paths and supply paths. The adjusting unit 37 can have a control or regulating unit 72, e.g. a control electronic mechanism 72, and/or a supply unit 71 (not shown here) for dosing and feeding tempering agent (for this see Figs. 8-11). The control electronic mechanism 72 then works for example according to pre-given data determined by means of a stored logic unit on setting members (e.g. valves) of the supply unit 71. The printing machine shown as example in fig. 2 is particularly designed as a rotor printing machine and has a printing mechanism 41 that has at least a inking device 42, a cylinder 43, e.g. a printing mechanism cylinder 43 designed as form cylinder 43, carrying a print form 44, as well as a counter pressure cylinder 46. The solution for printing machines described below for operational modes for a web velocity of more than 10 m/sec, especially greater than or equal to 12 m/sec. is particularly advantageous. The 16 print form 44 is preferably designed as print form 44 for flat printing (flat print form 44), particularly for waterless flat printing (waterless flat print form 44). The printing mechanism 41 is designed as printing mechanism 41 for offset printing and has between the form cylinder 43 and the counter pressure cylinder 46, another cylinder 47, e.g. a printing mechanism cylinder 47 designed as transmission cylinder 47 with a packing on its jacket surface. The transmission cylinder 47 forms along with the counter pressure cylinder 46 in a print-on-position over a printing substance 49, e.g. a printing substance web 49, a printing position 51. The counter pressure cylinder 46 can be another transmission cylinder 46 of another not denoted printing mechanism, or can also be a counter pressure cylinder 46 not carrying any ink, e.g. a steel cylinder or a satellite cylinder. The print form 44 can be designed as sleeve-shaped or even as one (or more) print plates 44, that is fastened or suspended with its end in at least one narrow channel not exceeding a width in circumference direction of 3 mm (indicated in fig. 2). Similarly, the packing 48 on the transmission cylinder 47 can be designed sleeve-shaped or even as (at least one) rubber blanket 48 that is similarly fastened and/or clamped in at least one channel. If the rubber blanket 48 is designed as multilayered metal print blanket, then the channel is also designed with the above mentioned maximum width. The inking mechanism 42 has an ink supply unit 52, e.g. an ink tub with a dip roller or a lifter, or a chamber wiper with ink feed, as well as at least a roller 53 that can be set against the form cylinder 43 in a print-on-position, e.g. an inking roller 53. In the shown example, the printing ink is transported by the ink supplying unit 52 over a roller 54 designed as screen roller 54, the roller 53, the form cylinder 43 and the transmission cylinder 47 on to the printing substance 49 (e.g. in web form or as sheet). There can also be at least one more, e.g. a second inking roller 53 depicted by dashed line, working together with the screen roller 54 and the form cylinder 43. The roller 54, i.e. here the screen roller 54, has recesses or cups on its jacket surface in order to take ink from a reservoir 61 for the printing ink, e.g. from an ink cartridge 61 containing printing ink, and transported on to an adjacent rotation body 53, e.g. the inking roller 53. 17 The printing mechanism 41 is designed as so-called "printing mechanism for waterless flat printing", particularly "waterless offset print" (dry offset), i.e. in addition to feeding of printing ink no further feeding of a damping agent for forming "non-printing" regions is required. In this method one can do away with application of a moist film on the print form 44, which otherwise in the so-called "wet offset" prevents the non-printing part on the print form 44 from taking up ink. In waterless offset printing this is achieved by using special printing ink and through special design of the surface of the print form 44. Thus for example, a silicon layer in the waterless offset printing can take over the role of the hydrophilic region of the wet offset to be coated with the damping agent and prevent the print form 44 from taking up any ink. Generally, the non-print areas and the print areas of the print form 44 are achieved by designing regions with different surface tension with alternate working of the printing ink. In order to print tone-free, i.e. without the non-print areas also taking up ink, one required a printing ink that is set in its easy flow (measured as tack value), that on the basis of the surface difference between printing and non-printing part on the print form 44, a smooth separation can take place. As the non-printing points are preferably designed as silicon layer, for this purpose a printing ink having the higher easy flow as compared to the wet offset is required. The easy flow according to the "roller offset print", Walenski 1995, raises a resistance, with which the printing ink of the film division in a roller crevice or while transmitting the ink in the print zone between cylinder and printing substance, counter-act. As the easy flow of the printing ink varies with temperature, in practical operation of the printing machine, the cylinders 43; 47 or the inking device 42 are tempered, especially cooled, and held at a constant temperature in order to avoid tinting for the changing operation conditions during printing. 18 The temperature dependence of rheological properties, e.g. the viscosity and/or the easy flow, is now brought into consideration for influencing and particularly regulating the printing ink to be transported from the reservoir to the printing substance 49. Instead of (or in addition) mechanical setting members, e.g. opening or shutting of wipers or alteration in speed of lifters or film rollers, by altering the temperature on the jacket surface of at least one of the rotation bodies 43; 47; 53; 54 involved in the printing process, the result of the comparison of the desired ink density D2 with the determined actual ink density Dl can be influenced. Apart from separating printing and non-printing regions, the easy flow of the printing ink however also influences the intensity of cracking during co-acting of an ink-carrying cylinder 43; 47 and the printing substance 49. Especially when the printing substance 49 is designed as uncoated and less dense newspaper material with very good soaking properties, i.e. with open pores and very little repelling time, there is increased danger of release of fibre or dust caused by cracking. The danger however is also there for lightly coated or light-weight coated paper types used in roller offset printing with a coating weight of say 5-20 gm/m2, especially 5-10 gm/m2 or even lesser. Tempering is overall suited for uncoated or coated papers with a coating weight of lesser than 20 gm/m2. For coated papers, tempering of the ink-carrying cylinder 43; 47 is advantageous when it is determined that the coating is "offset" by increasing of easy flow of the paper (at least partly). In order to keep cracking on the printed substance 49 or build-up of the printing ink on the packing 48 of the transmission cylinder 47 and/or the print form 44 of the form cylinder 43 as low as possible, the printing ink for the application purpose and the expected operating conditions is produced and used in such a way that it is at the lower limit of the easy flow as far as possible. In an extension, one or more of the ink-carrying components, like e.g. in an advantageous design of the printing mechanism cylinder 43 designed as form cylinder 43 as ink- carrying component 43, or/and the printing ink itself, can simultaneously be tempered in 19 relation to the production speed V of the printing machine, for which a correlating signal with the production speed V of the printing machine is tapped on the ink-carrying transmission cylinder 47 with the help of a sensor, e.g. with a rotation generator (not shown) and set to the adjusting device 37 (shown dashed in fig. 2) and/or to the evaluation unit 23. The temperature on the jacket surface of at least one of the rotation bodies 43; 47; 53; 54 involved in the printing process, preferably in the form cylinder 43, is not kept constant here, as is otherwise usual in waterless offset printing, for all production speeds V in a certain temperature range, but reveals for different production speeds V different rated temperature T i;rated. The rated temperature T i,rated is adjusted with the help of the adjusting device 37 in relation to the production speed V in such a way, that the easy flow of the printing ink for any desired production speed V lies within a pre-given window of tolerable tack values. For a higher production speed V, an increased value is selected for the rated temperature T i,rated of the corresponding component 43 or the printing ink. One regulation is based on the principle that for the desired, directly next or the actually adjusted production speed V as guiding parameter on account of a systematic allocation of a certain rated value or maximum value for the rated temperature T i,rated of the component 43 or the printing ink as initial parameter is foreseen. The rated value or maximum value in both cases represents a default temperature that corresponds in the first case to a temperature to be maintained, and in the second case to an upper limit of a permissible temperature. On the basis of an inline conducted scanning of the ink density Dl actually applied on the print substance 49 by the printing process, with a photo- electric sensor 56, preferably an image sensor 56, especially a CCD-cameral 56, and comparison of the different scanned values with the rated value foreseen in this printing ink density D2, the temperature is however varied and fine-tuned till an adequate conformity between the actual ink density Dl and the desired ink density D2 is achieved. If there are other conditions, e.g. a printing ink with mainly other properties, especially with respect to its consistency, or a printing substance 49 that has a surface structure different from that of uncoated new paper material and/or has a completely different 20 cracking behaviour, then the valued of the relationship between the mentioned values can vary significantly. Common is however the solution nevertheless of adjusting the temperature of the form cylinder 43 in relationship of production speed V, and in such a way that in the range of higher production speed V it has a higher rated value or maximum value and for a region of a lower production speed V. In this way cracking between the ink-carrying cylinder 43; 47 and the printing substance 49 is reduced and in the ideal case almost prevented. The above mentioned relationship between a determined ink density variations and a temperature alteration and/or between temperature on the jacket surface at least one of the rotation body 43; 47; 53; 54 involved in the printing process and the production speed V of the printing machine, can be stored for different printing ink and/or printing substance type. Even the printing operation then the specific relationship for the respective printing ink and/or the concerned printing substance 49 is used. For this, see also the descriptive part of the design example shown figs. 6 and 7. In an advantageous design at least the screen roller 54 and the formed cylinder 43 has a tempering device 57; 58 acted upon by a fluid tempering agent, e.g. water, acting from its interior to its respective jacket surface, whereby the temperature on the jacket surface of the screen roller 54 with respect to the ink quantity to be transmitted from it and the temperature on the jacket surface of the formed cylinder 43 under consideration of the production speed V of the printing machine for avoiding crack and/or toning is adjusted, preferably controlled or regulated. The adjusting device 37 is designed according to the case in question, whether the process is controlled or regulated, as a control unit 37 or as a regulating unit 37. In the case of design as a control unit 37 there is no feedback through photo-electric sensor 56 or the signal of data supplied by it. For controlling the temperature of the jacket surface of the screen roller 54, in the fore- field of production for the interested pairs printing ink/paper of various production speed V that temperature (empirical) is determined, at which the desired ink density can be determined on the product. During regulation of the temperature on the jacket surface of 21 the screen roller 54 the actually adjusted temperature can be determined with the help of at least one of the thermo-sensor 59 arranged on or at least near to the jacket surface to the screen roller 54, whose output signal is fed to the adjusting device 37 or the evaluating unit 23 and then adjusted afresh if required in relationship to a comparison with temperature with rated temperature conducted in the adjusting unit 37 or the evaluation unit 23 and continued with it in order to convey the ink quantity required for the printed image. Parallel to the control/ regulation of the temperature on the jacket surface of the screen roller 54 the temperature of the jacket surface of the form cylinder 43 is controlled or regulated in relationship of the production speed V (sometimes additionally dependence on the printing substance and/or the printing ink), whereby regulation of the temperature on the jacket surface of the form cylinder 43 under application of a further (not shown) thermo-feeler is similar to that of regulation of the temperature on the jacket surface of the screen roller 54. This is however not additionally varied through the result of the output unit 23, but it correlates with the production speed V of the printing machine. It is of advantage that a temperature to be adjusted for a value of the production speed V of the printing machine on the jacket surface of the roller, especially the screen roller 54 and/or the cylinder, particularly the form cylinder 43, is adjusted or at least adjustment/setting of this required temperature is started before the printing machine sets the new value of the production speed V, so that the temperature adjustment with respect to a desired alteration in the production speed V takes place in an advanced manner. By means of this pre-control an otherwise systematically occurring error can be avoided, as due to a time-advanced adaptation of the temperature adjustment the quantity of produced wastage as a result of unsuitable temperature adjustment can be significantly reduced. Because the adaptation of the temperature adjustment reacts at least more slowly, i.e. with a longer reaction time till reaching a stable operating condition, than the alteration in production speed V that is carried out with the help of electronically controlled or regulated drives. In this way a desired alteration is production speed V that is for example displayed through a corresponding manual input on the input and output unit 33 22 belonging to the evaluation unit 23, e.g. can be programme-technically delayed by the evaluation unit 23 in its execution till the tempering unit 57; 58 has reached the temperature required for the new production speed V and to be set o the jacket surface of the screen roller 54 and/or the form cylinder 43 completely or at least to a significant extent of clearly about 50%, preferably above 80%, ideally above 90%. The above described measures are suitable with respect to the screen roller 54 alone or for the printing machine as a whole and also foreseen for the reason that the temperature to be set on the jacket roller of the screen roller 54 can be adjusted in relation to the production speed V of the printing machine in such a way, that with increasing production speed V of the printing machine a reducing capacity of the recesses designed on the jacket surface of the screen roller 54 for transmission of ink on to the rotation body 53 adjacent to the screen roller 54 is compensated by a reduction in viscosity of the ink caused by the set temperature. Because, with increasing production speed V of the printing machine the recesses or cups on the jacket surface of the screen roller 54 filled with printing ink get increasingly incompletely emptied, so that the worsening transmission behaviour of the screen roller 54 can be compensated by an adapted thinning of the printing ink to be transmitted, whereby the reduction in viscosity of the printing ink takes place with the help of the temperature to be set on the jacket surface of the screen roller 54. In another advantageous design the tempering unit 57; 58 is designed in such a way that the temperature set with the adjusting device 37 allocated to this tempering unit 57; 58, on account of a pre-given functional allocation for a value of the production speed V of the printing machine on the jacket surface of the roller 54, and/or the cylinder 43, particularly the form cylinder 43 can be altered within fixed limits by manual adjustment. In this way one has an intervention possibility into pre-machine-given settings, whereby within a maximum permissible tolerance range defined by bound values of e.g. +/- 5% or 10% with respect to the default value can be manually fine-tuned as required. The bound values can be symmetrically or unsymmetrical distanced from the default value and for example define even a tolerance range between -5% and +10%. 23 Fig 3 shows an example of a functional relation, (e.g. equation B in Fig. 6) as to how the rated temperature T i,rated on the jacket surface of at least one of the rotation bodies 43; 47; 53; 54 involved in the printing process can be dependent on the production speed V of the printing machine. The functional relation can be linear or non-linear. In any case, on the basis of the functional relation for a printing process fixed on account of the used printing ink and the used print substance 49 in relation to production speed V of the printing machine, a suitable value for the rated temperature T i,rated to be set on the jacket surface of at least one of the rotation bodies 43; 47; 53; 54 involved in the printing process can be determined. The mechanically determined value for the rated temperature T i;rated to be set on the jacket surface of at least one of the rotation bodies 43; 47; 53; 54 involved in the printing process can be manually altered within pre-given limits in the sense of a fine tuning, which is indicated in Fig. 3 by a vertical double arrow enclosed by boundary lines. Fig. 4 similarly shows as an example a functional relation of an ink quantity conveyed by the screen roller 54 in relationship to the production speed V of the printing machine. By adapting the temperature T on the jacket surface of the screen roller 54, especially the viscosity of the printing ink to be conveyed can be altered in such a way that the conveying rate on altering the production speed V of the printing machine remains at least almost constant. This can be done by means of a pre-retained equation (e.g. Equation A in Fig. 6) between production speed V and a rated temperature T i;rated. Especially the conveying rate of the screen roller 54 can however be made alternatively or in addition to its dependence on the production speed V of the printing machine be made dependent on a determined variation in the actually determined ink density Dl and on the ink density D2 pre-given as rated value. The index "i" or "j" in the rated temperature T i,rated or T i,rated is supposed to indicate that this could have to do with several stored relationships A; B for different components 43; 54 and/or ink types F and/or paper sorts. Thus in the storage unit 34 of the adjusting unit 37 respectively a quantity of different relations A; B at least for the respective rated temperature T i,rated; T j,rated of the screen roller 54 and the form cylinder 43 are stored, to 24 which one can have access through the input and output unit 33 of say the adjusting unit 37. Fig. 6 and 7 show in a display mask and/or input mask a design example for a tempering, where the prescribed rated temperature T i,rated; T j,rated of the component 43; 54 to be tempered - here the screen roller 54 and the form cylinder 43 - is given in the relationship A for the form cylinder 43 and B for the screen roller 54 to the production speed V. For this, in a storage unit 34, e.g. in a data bank of the control post computer, of the adjusting unit 37 or the evaluation unit 23, for different printing inks or ink types colour-specific curves/graphs (analytical) or support points (tabular) are stored for the relationship between rated temperature T i,rated; T j,rated of the concern component 43; 54 and the production speed V. As one can see in fig.6 there are own relationships A; B (curves or tables) for tempering of screen roller 54 and form cylinder 43. The curves shown in fig.6 are based on pre-retained support points particularly in a data bank of the storage unit 34 for a particular selected ink type F (here for example "HUBER MAGENTA"). Selection of the ink type F and hence the relationship can take place for the screen roller 54 and/or the form cylinder 43 from a list, e.g. through a mask or a menu corresponding to fig.7. While selecting a printing ink or ink type F the stored relationship A; B (a curve and/or the stored support points) is loaded and drawn as basis for adjusting the tempering of this component 43; 54. The curves or support points can be stored in the storage unit 34 in an alterable and subsequently altered manner by the operating personnel for carrying out an adaptation. On the basis of this pre-retained relationship A; B or connections a required target temperature or rated temperature T i,rated; T j,rated of the component 43; 54 to be tempered is defined for the existing production speed V, given out as prescribed value for the rated temperature T i,rated; T j,rated and converted for example through a supply unit 71 with control electronic mechanism 72 as described in details below. Advantageous is a design, according to which a pre-retained relationship A; B (as curve and/or as series of support points) can be corrected upwards or downwards by the 25 operating personnel altogether absolutely or relatively. This is expressed in fig.6 (respectively for the form cylinder 43 and the screen roller 54) by the input field "Temp.- Offset [%]" and the input field "curve alteration". In this way the relationship A; B for the selected ink type F can basically be retained; an adaptation to particular ink density requirements and/or an adaptation to the requirements of different print substances can however be taken up manually through an input on the display mask and/or input mask (fig. 6 and 7) displayed on the monitor of the input and output unit 33. In the variant "Temp.-Offset [%]" however, the stored and displayed relationship itself is not changed but nearly the desired value obtained for the subsequent regulating cycle is subjected to the alteration. Thus the pre-retained relationship A; B or curve is basically retained; the alteration has an effect merely on the selected printing mechanism. In the second variant "curve alteration" the relationship (curve or series of support points can actually be altered. It can be foreseen that this takes place by adding a constant (total raising or lowering) and/or in a percentage manner (spreading or crushing). In this example, for the form cylinder 43 the target or rated temperatures T i,rated for production speeds V of 5000 cylinder rotations per hour lie preferably between 20 and 24°C and for 35000 cylinder rotations per hour between 24 and 28°C. For the screen roller 54 the target or rated temperatures T i,rated for production speeds V of 5000 cylinder rotations per hour lie between 22 and 27°C and for 35000 cylinder rotations per hour between 31 and 36°C. From fig. 5 we can see that several cycles for tempering separated from one another can be foreseen in the printing machine, namely particularly a supply cycle K2, e.g. cycle K2 for at least one of the printing mechanism cylinders 43; 47 and/or the screen roller 54, as well as another supply cycle K3, e.g. cycle K3 for the drives M of the printing mechanism cylinders 43; 47 and/or the screen roller 54 and/or if required for the regulator allocated to these drives M as components M to be tempered. 26 The tempering agent consisting mainly of water (with or without additives) for tempering the printing mechanism cylinders 43; 47 and/or the screen roller 54 is made available through a cooling unit 77, e.g. a cold central unit 77, in a temperature range between 10°C and 25°C, whereas the tempering agent for tempering the drives M of the printing mechanism cylinders 43; 47 and/or the screen roller 54 is readied in a temperature range between 24°C and 30°C. As described in more details below, this whole central unit 77 can have an air-cooled condenser and/or a free cooling unit and/or a booster cooling for a peak capacity at higher surrounding temperatures, e.g. in summer, and/or a heat exchanger for heat recovery and/or a compressor-cold machine. As explained below it should preferably have at least two of these cooling units 77. Through heat recovery, e.g. a unit/device for heat recovery 66 as described for example in fig. 12 and 13, 5 - 10% of the cooling capacity of the cooling processes 87 (see below) can be recovered. This recovered energy can be drawn for an internal utilisation 64, like for example a building tempering, hot water preparation, a building air moistening or for fresh air pre-heating and/or even as (part) energy source for a hot water storage 76 (see fig. 5 and 8). As schematically shown in fig. 5 the heat recovery 66 can be from different sources, e.g. indicated by the heat flow 68 and 69 from the reflux of the supply cycle K3 and/or K2 and/or even as indicated by the heat flow 63 from the surrounding air heated in the region of the printing units or from the heated product flow. Especially tempering of the 43; 54 through tempering agents and heat recovery leads to the fact that the printing machine releases heat only to relatively less extent to the surrounding air and/or to a sample flow of print products produced by it, so that the energy fed by energy sources 67 into the printing machine, particularly electrical energy of say several KVA is utilised with a high degree of effectiveness. 27 The hot water storage 76 has for example a holding capacity of approx. 1 m3 for each printing tower 73 (see below) and feeds to the tempering unit 57; 58 of the printing mechanism cylinders 43; 47 and/or the screen roller 54 the stored tempering agent at a temperature Tl of say between 50°C and 70°C for a relatively short time period of say 3 to 4 minutes during run-up of the printing machine, in order to set the temperature on the jacket surface of the printing mechanism cylinders 43; 47 and/or the screen roller 54 to at least 50°C, e.g. 55°C, at least for the period of run-up of the printing machine. Due to the increased temperature Tl of the tempering agent from the hot water storage 76 the printing machine is brought to its working temperature within a short time, which has a favourable effect on the quality of print products produced during start-up of the printing machine. Ejection of start-up wastage is thereby reduced. The following designs for control of tempering and supply with tempering agent are particularly advantageous in conjunction with one or more of the already mentioned design features, e.g. with the regulating cycle for ink density in connection with the evaluation unit 23 and/or with tempering of the screen roller 54 in relation to the speed and/or with tempering of the form cylinder 43 in relation to the speed. For details on this refer to explanations above. Supply of tempering agent to the components 43; 54 takes place as shown in fig. 8 through decentralised supply units 71, which along with a control electronic mechanism 72 (on location) form for example a decentralised adjusting unit 37 for one or more printing mechanisms 41. The adjusting unit 37 or the supply unit 71 is preferably allocated to a group of printing mechanisms 41, which together form at least one printing unit 73. For example, the printing unit 73 represents the group of all printing mechanisms 41 allocated to a web to be printed on and/or it forms a printing tower 73. Fig. 8 shows on the right side a first section with a printing tower 73 and a folding apparatus 74 and on the left side a second section 28 with two printing towers 73 and an allocated folding apparatus 74. The supply unit 71 can be allocated to one or more adjacent printing towers 73 of a section. In this supply unit 71 there are supply lines and regulating valves (described further below) for the desired supply of required tempering agent at a suitable temperature to the components 43; 54 to be tempered. The supply unit 71 or the allocated control electronic mechanism 72 receives from a super-ordinate control unit 75, e.g. a logic system implemented in the machine control or a control room computer, either directly the above mentioned desired or rated temperatures T i,rated after these have been determined as described above on the basis of stored equations A; B, or the control electronic mechanism 72 receives at least data regarding ink type F and/or production speed V, which enables a logic system implemented in the control electronic mechanism to determine the desired or rated temperature Ti,rated on the basis of equations A; B stored there. The supply units 71 arranged decentralised in the printing machine plant close to the printing tower are now connected to a first supply cycle Kl, which supplies tempering agent at a first temperature range Tl above the surrounding temperature to the supply units 71 purely for heating purposes. This tempering agent can either be heated as required, as for example in a run-through heater. Ideally however, a suitably tempered stock is already retained in a storage 76, e.g. a tempering agent storage 76 or a heating fluid storage 76, particularly a hot water storage 76. Energy supply to these or the heating is not discussed here in details. This can takes place with usual heating appliances, with or without released heat utilisation, on the printing machine. In an advantageous design with released heat utilisation at least a portion of the heating energy can be used for the storage 76, e.g. through heat recovery 66, especially heat recovery 66 according to or similar to fig. 13 with heating pump 121. A pump 70 (see fig. 11) transporting the tempering agent in the cycle K3 can ideally be foreseen in a line branch of cycle K3 or even in the region of the hot water storage 76. 29 The supply unit 71 is further connected at least to a second cycle K2 which supplies tempering agent at a second temperature range T2 to the supply unit 71 for tempering purposes, which depending on the actual requirement could basically be in a range of say between 5°C and 30°C, preferably 8 to 25°C, ideally 10 to 15°C. Depending on the requirement of the desired component temperature, more or less of the tempering agent from this supply cycle K2 is mixed with a tempering cycle KFZ; KRW (see below) tempering the component 43; 54. For readying the tempering agent a cooling unit 77, e.g. a cold central unit 77, has at least a corresponding cooling process (also tempering agent source), preferably however two different cooling processes (tempering agent sources) with respect to energy. The tempering agent of this level can come in direct or indirect relationship to the level of outside temperature and the temperature level T2 required by the printing machine, as desired from the different cooling processes or tempering agent sources of the cold unit 77 or generally as is specific mix of tempering agent from both cooling processes that are energy-wise different (see below). Details about the nature and manner of how this can be readied by a cooling unit 77 are further described below in fig. 11. A pump 80 transporting the tempering agent in the cycle K2 can ideally be foreseen in a line branch of the supply cycle K2 in the supply unit 71, or even in the cold unit 77. In a design shown as dashed line in the right hand part of fig. 8, a third cycle K3 is foreseen that is similarly supplied by the cold unit 77. The cold unit 77 (see below) provides tempering agent to this supply cycle K3 at an 'average' temperature level T3 that lies at a higher temperature range as compared to the cycle K2, e.g. 20 to 35°C, particularly 24 to 30°C. The requirement or definition of the desired temperature level T3 to the cold unit 77 takes place through a computing and/or control unit 100 of the printing machine on a logic unit 92, e.g. control 92 of the cold unit 77 (see fig. 11). The computing and/or control unit 100 30 and the control unit 75 can be designed as a single control unit or as components of the same control unit. In an alternative shown by dashed line in fig. 8 and 9, the cycle K3 is connected to the decentralised supply unit 71 and the tempering agent is fed to the receivers (see below: drives M and/or drive regulators) of the printing towers 73 not directly as described above but through the supply unit 71. Fig. 9 shows an advantageous extension of the decentralised supply unit 71 that contains at least both the supply cycles Kl and K2 as well as in a possible design version (dashed line) the supply cycle K3. The supply unit 71 is allocated to a group of n printing mechanism 41, which here form the printing mechanism 41 of a printing tower 73 (e.g. fig. 8, right). For reason of better overview only two cylinders 43 to be tempered, e.g. form cylinders 43, and two rollers 54, e.g. screen rollers 54, are shown, which ultimately corresponds to two print points, e.g. a double print point for simultaneous both-sided printing of two transmission cylinders 47 placed against one another in rubber-against-rubber operation. In the shown design form preparation of the tempering agent takes place in the tempering cycle KFZ, short cycle KFZ of the form cylinders 43 pair-wise, i.e. always two form cylinders 43, particularly those of a common double print point are supplied parallel with the prepared tempering agent. Basically, depending on the requirement, it is also possible to allocate a tempering cycle KFZ to each individual form cylinder 43 or even larger groups (e.g. four, six or eight) of form cylinders 43. The tempering takes place in such a way that in the tempering cycle KFZ the tempering agent, driven by a pump 81, circulates and thereby flows through the allocated component(s) 43; 54 to be tempered, especially their tempering unit 57; 31 58. At the crossing point 82 tempering agent from one of the supply cycles Kl (for heating purposes) or K2 (for cooling purposes) can be fed and an adequate quantity can be discharged at the crossing point 83. Selection of the dosage of tempering agent takes place through the position (opened or closed) of valves 78. Remote-controlled switching valves 78 in corresponding line branches and connected to the supply cycles Kl; K2. After connecting the line branches dosage of the selected tempering agent takes place in the tempering cycle KFZ through a remote-controlled dosage valve 79. At the crossing point 82 the dosed quantity gets mixed with the tempering agent circulating in the tempering cycle KFZ, whereby quick mixing can be further accelerated by a (not shown) turbulence chamber between crossing point 82 and pump 81. A desired/rated value for a temperature of the component 43; 54 (explained here on the basis of a form cylinder pair representative of individual or groups of form cylinders 54 or screen rollers 54) can be generated on principle in different ways and should now be converted in the supply unit 71 for this component 43; 54. The value for the desired or rated temperature T i,rated of the component 43; 54 to be tempered can be given as described above for fig. 6 and 7 in relationship to the production speed V, whereby additionally also the ink type F and/or paper type to be used can be considered. In the simplest version of the regulating cycle the conversion can take place in a manner that at least a measured value m2 for the temperature of the tempering agent is determined shortly before entry into the component 43; 54 and/or a measured value m3 for the surface temperature of the component 43; 54 excel, e.g. as measured value m3 of an intra-red sensor directed on to the roller surface, is determined and compared with the relevant desired/rated value in the control electronic mechanism 72. Depending on the variation, tempering agent from one of the supply cycles Kl or K2 is fed into the cycle KFZ (or KRW, see below) through the dosage valve 79. Selection of the required cycle K2; K3 (temperature level Tl or T2) takes place through a corresponding setting command SI; S2 from the control electronic mechanism 72 to the switching valves 78 (e.g. one closed and the other open); dosage of the required injection quantity takes place 32 through a setting command S from the control electronic mechanism 72 through the dosage valve 79. An advantageous extension of the described regulating cycle reacts significantly faster with a measured value ml for the temperature shortly after mixing at the crossing point 82, particularly after a turbulence chamber and still before the pump 81, a measured value m2 of the temperature of the tempering agent shortly before entry into the component 43; 54 (already in the region of the corresponding printing mechanism 41) and/or a measured value m3 (of an intra-red sensor) for the surface temperature of the component 43; 54 or of the ink present on it itself, and a measured value m5 for the temperature of the tempering agent in reflux (already again in the supply unit 71) before the crossing point 83. In an extension also additionally a measured value m4 can be taken up shortly after exit from the component 43; 54 (still in the region of the corresponding printing mechanism 41). These measured values ml to m3 and m5 as well as, if required, m4 are now jointly processed in a multiple-cascading regulating cycle under consideration of running time corrections and pre-controlled members, as described in details in the document WO 2004/054805 Al, the content of which is specifically referred to in this context. Especially by using the measured value ml shortly behind the dosage point, if required after a turbulence stretch but before the pump 81, it is possible to significantly reduce the reaction time under consideration of regulating stretch information, as compared to a regulation where only measured values m3, m4 or m5 are taken into account. The result of an intervention in the last mentioned case is noticed and taken into account only much later. Also measured values m6 and m7 are taken for recording the temperatures in the feed- flow lines of the supply cycles Kl and K2 and fed to the control electronic mechanism 72 for consideration. The structure and effectiveness of a tempering cycle KFZ; KRW was described in fig. 9 merely on the example of the form cylinder 43. However this has to be similarly applied 33 to the other tempering cycles KFZ of other form cylinders 43 allocated to the supply unit 71, as well as to tempering of the screen rollers 54. In the example the screen rollers 54 are tempered individually to a number of 1 independently controllable tempering cycles KRW short cycle KRW, which are connected to both the cycles Kl and K2. This has the background that in this way for each individual screen roller 54 the ink quantity to be transported can be set. For the sake of safety the tempering cycles KRW of two screen rollers 54 of a double print point are connected to one another through bypass lines that can be closed. For this, corresponding valves 84 are foreseen. If for example, in one of both cycles KRW, a pump 81 or dosage valve 79 fails, then temporarily tempering of the endangered component 43; 54 can be taken over by the corresponding cycle KRW after opening and closing corresponding valves 84. The same is indicated by dashed line for the cycle KFZ of the form cylinders 43, whereby tempering of two form cylinders 43 affected by the breakdown can be taken over by an adjacent cycle KFZ of two other form cylinders 43. If also the cycle K3 is coupled to the supply unit 71, then the principle of mixing of tempering agent from the cycle K3 into a tempering cycle KAN short cycle KAN, by which one or more groups of drives M of the printing unit 73 can be tempered, can be applied (see dashed line depiction of K3 in fig. 9). In this case the preparation of this cycle KAN is controlled by the allocated dosage valve 79 in relationship to the measured value ml directly after feeding and/or in relation to the measured value m5 in the reflux. As no heating up is required here, the tempering cycle KAN is connected only with one supply cycle K3. As the drive tempering is less critical than that of the form cylinders 43 or rollers 54, here a larger number of n drives M can be tempered by a common cycle KAN. It could be advantageous if a number of m = 2 cycles KAN is foreseen to respectively supply to one half (left or right side of a printing unit 73 or printing tower 73) (see fig. 10). In both cycles K2 and K3 the inlet and outlet line in the region of their end away from the cold unit 77 are preferably connected to one another through at least one bypass line that 34 can be opened or closed by means of switch-able valves 85. If the cycles KFZ and KRW take up very little tempering agent then this valve 85 can be opened in order to maintain an adequate fluid flow and thus retain a correctly tempered tempering agent in the feed line for the cycles KFZ and KRW. Here two or more bypass lines can be used for each cycle Kl; K2 with valves 85 of different flow cross-sections, or even one valve 85 per cycle, whose flow quantity can be controlled. Thus the circulation quantity can be set/adjusted staggered according to requirement. In the cycle K2 always at least a small quantity of tempering agent circulates, so that if tempering agent of suitable temperature is required the reaction time is as short as possible. Fig. 10 shows an advantageous extension of a printing tower 73 with a number of i = 8 printing mechanism 41 which here form a number of h = i/2 = 4 double print points or double printing mechanisms 62 for simultaneous both-sided printing with two transmission cylinders 47 placed against one another in rubber-against-rubber-operation. The supply unit 71 with control and regulating unit 72 is allocated to the printing drum 73. As shown explicitly only for the bottom-most of the four double printing mechanisms 62, each screen roller 54 of the printing tower 73 has its own cycle KRW. The form cylinders 43 belonging to the same double print mechanism 62 pair-wise have a common cycle KFZ. All rotary drives M, the screen roller 54 and form and transmission cylinders 43; 47 of the same side of the print material web 49 are connected to a common cycle K3. Thus for this printing tower 73 one obtains k = 4 cycles KFZ, 1 = 8 cycles KRW and m = 2 cycles KAN according to fig. 9. All form and transmission cylinders 43; 47 as well as screen rollers 54 have as drives M individual drives mechanically independent of one another, so that for each cycle KAN a number of n = 12 drives M can be tempered. For supplying the printing machine or the supply units 71 with tempering agent of the second cycle K2 and also the third cycle K3 the cold central unit 77is foreseen. In a particularly advantageous design form the cold central unit 77, as shown in fig. 11, is 35 designed as combination plant that has two cooling processes 86; 87 coupled with one another, namely a first process 87 with a unit 89, 90, 91, e.g. cold machine 89, 90, 91 for generating compression cold, and a second process 86 with a unit 88 for cooling with the help of surrounding or atmospheric air. The first process 87 is designed for cooling a tempering agent to a temperature level Tk below the surrounding or atmospheric temperature. However, it is important that the processes 86; 87 are coupled with one another in such a way that both above mentioned cycles K2; K3 can be supplied with cold by both processes 86; 87. Depending on the requirement of temperature level T2; T3 of the concerned cycle K2; K3, this supply can take place through one or the other process 86; 87 as desired, or by a combination of both processes 86; 87. For this, an intelligent control 92 is foreseen for readying the tempering agent for the cycles K2; K3 by optimum utilisation of the unit 88 for cooling with the help of surrounding or atmospheric air. The second process 86 has in a first cooling agent or fluid cycle 93 the unit 88 for cooling with the help of surrounding or atmospheric air, in short free cooling unit 88, which for example can be designed as convection cooler with or without evaporator. The energy exchange takes place through thermal contact between the fluid of the fluid cycle 93 and the atmospheric air and in case of additional spraying with water also makes use of the evaporation cold. The free cooling unit 88 is thermally coupled through the fluid exit- side to the cycles K2; K3 - e.g. respectively through a heat exchanger 94; 96. It is especially coupled on to the refluxes of both cycles K2; K3, from which part-flows 106; 107 can be taken away after flowing to the heat exchangers 94; 96 through regulate-able valves 103; 104 for feeding again into both the cycles K2 and K3. The more or less big de-coupled part-flow 108; 109 is brought into thermal contact with the first process 87 before the required quantity of fluid cooled in this process 87 is fed into the cycles K2; K3 through the valves 103; 104. For regulating the flow volume passing through the heat exchangers 94; 96 on the side of the fluid cycles 93, a regulate-able valve 97; 98 is respectively foreseen, which divides the fluid flow into a flow through the heat exchanger 94; 96 and a flow flowing into the reflux to the unit 88. Conveying of the fluid takes place for each heat exchanger branch by means of a pump 99. 36 The first process 87 is foreseen in order to reduce the fluid of the de-coupled part-flows 108; 109 to a temperature level Tk under atmospheric temperature and for readying it for re-coupling into the cycles K2; K3. For cold generation the first process 87 has cold agents in a fluid cycle 101, the unit 89, 90, 91 for generating compression cold that has a compressor 89, a cooler 91, e.g. as free cooling unit 91 and a relaxing valve 90. The unit 89, 90, 91 or the first process 87 is thermally coupled with the cycles K2 and K3 behind the relaxing valve on the exit side. The process 87 is coupled through the heat exchanger to part-flows 111; 112 for return-feeding of previously de-coupled and subsequently cooled fluid into both the cycles K2 and K3. Between heat exchanger 102 and the valves 103; 104 a storage 113 can be arranged, from which the part-flows 111; 112 can be served and in which the de-coupled part-flows 108; 109 are guided. Thus through a pump 114 fluid from the storage 113 can be continuously conveyed in a circle through the heat exchanger 102 and, on the other side, cooled fluid can be taken as required for re-feeding into the cycles K2 and K3. Both the refluxes from K2 and K3 are thus first brought into thermal contact with the second process 86 before they can be respectively divided as required by the respective rated temperatures T2rated; T3rated into two part-flows, where one part-flow is straight away fed into the supply flow of the concerned cycle K2; K3, whereas the other part-flow is brought in thermal contact with the first process 81, before fluid cooled in this process 87 is similarly fed back into the supply flow of the concerned cycles K2; K3. The respective ratio/relationship between the flows 106 to 111 or 107 to 112 is set by the control and can basically lie from 0% to 100% to 100% to 0% of the respective set feed flow 116; 117, i.e. the feed flow 116; 117 can be prepared from a mixture of both part- flows 106 and 111 or 107 and 112 or even only from one of the part-flows 106 or 111, or 107 or 112. If this is not prepared and conveyed in the supply unit 71, as described above and indicated by continuous lines in fig. 8 and 9 for the cycle K3, a pump 95 can be foreseen in the feed flow 116 of the cycle K3. In the case shown by dashed line in fig. 9 the corresponding pump 95 can be foreseen in the supply unit 71. 37 The control 92 receives from a computing and/or control unit 100 of the printing machine rated temperatures T2rated; T3rated for the temperature levels T2; T3 in the initial run of the cycles K2; K3 and from a thermometer the outside temperature TA. The computing and/or control unit 100 can be part or process of a machine control, a control computer or even a process in another control unit allocated to the printing machine. Depending on the rated temperatures T2rated; T3rated and the outside temperature TA the cooling strategy is laid down by the control 92 and through only indicated signal contacts the resulting settings of the concern valve 103; 104 are done, e.g. regulating valves 103; 104 (and if required 97; 98) as setting members 103; 104 (97; 98). Possible operating situations are described as example below for a certain given value of rated temperature T2rated; T3rated, e.g. T2rated having a value between 10°C and 25°C and T3rated having a value between 24°C and 30°C. If the outside temperature TA of air is say TA 77, i.e. the rollers 54 and cylinders 43 takes place to a maximum of approx. 50% through the process 86, e.g. the free cooling unit 88 and the remaining requirement through the cold machine 89, 90, 91. The cooling or supply of the connected cycles K3, i.e. the drives, takes place up to 100% to the free cooling unit 88. The feed flow 116 is fed up to 100% from the part-flow 106. With increasing outside temperature TA to say approx.20°C the cooling or supply to the cycles K2 connected to the cold unit 77 takes place to an increasing extent to a cold machine 89, 90, 91 and lesser and lesser to the free cooling unit 88. The cooling or supply of the connected cycles K3 can still take place up to 100% through the free cooling unit 88, if for example a rated temperature T3rated of say 24 to 30°C is pre-given. If the outside temperature TA lies at approx. 20 - 24°C then cooling or supply of the cycles K2 connected to the cold unit 77 takes place exclusively through the cold machine 89, 90, 91; the feed flow 117 into the cycle K2 takes place up to 100% from the part-flow 38 112. Cooling or supply through the connected cycles K3 now takes place only partially through the free cooling unit 88 and the remaining part to the cold machine 89, 90, 91. If the outside temperature is say approx. 24°C or more, the cooling or supply of the cycles K2 and K3 connected to the cold unit 77 takes place only through the cold machine 89, 90, 91. In addition to the described outside temperature influence the pre-given data for the rated temperatures T2rated; T3rated, particularly the rated value temperature T2rated, could vary with the machine status of the printing machine, especially with the production speed V. Important for generating the rated value T2rated is however the lowest required/rated value temperature of all printing mechanisms 41 or their form cylinders 43 and screen rollers 54 to be supplied by the cold unit 77. Adherence to this lowest rated temperature must be ensured by the pre-given value of the rated value temperature T2rated. If this lowest rated temperature for the component 43; 54 to be tempered gets altered with run-up of the machine to higher production speeds V, then the rated value temperature T2rated can also be increased by the computing and/or control unit 100. By raising the rated value temperature T2rated the above mentioned threshold temperatures for the different cooling combinations can however also go up. Fig. 12 and 13 show two advantageous extensions in which a portion of heat energy is recovered. These extensions can be integrated individually or together into the above mentioned tempering. In the first version (fig. 12) a direct utilisation of the hot reflux takes place, e.g. with maximum temperature of 35 to 40°C, preferably approx. 38°C, from the cycle K3 to tempering of the drives M, for example by a fluid-gas-heat exchanger 119, e.g. a heat exchanger-heat register, for direct air heating during winter operation. In the second version (fig. 13) utilisation of the tempering agent reflux from the cycle K2 takes place as heat source for a heating pump 121. Through the heating pump 121a 39 higher temperature level, e.g. up to 55°C, can be attained in a storage 122 than in the version shown in fig. 12; however, additional structural complication and energy consumption is required. Both recovery concepts shown in fig. 12 and 13 can however also fall back on the other source (K2 or K3) - e.g. in fig. 12 on the reflux of K2 and in fig. 13 on the reflux of K3. The systems can also fall back on to the heat flow 63 (see fig. 5) as source. 40 List of reference signs 1 Printing mechanism 2 Printing mechanism 3 Printing mechanism 4 Printing mechanism 05 6 Form cylinder 7 Form cylinder 8 Form cylinder 9 Form cylinder 10 11 Transmission cylinder 12 Transmission cylinder 13 Transmission cylinder 14 Transmission cylinder 15 16 Counter pressure cylinder, transmission cylinder 17 Counter pressure cylinder, transmission cylinder 18 Counter pressure cylinder, transmission cylinder 19 Counter pressure cylinder, transmission cylinder 20 21 Print carrier, print sheet, material web, paper web 22 Image sensor, colour camera, flat camera, semi-conductor camera 23 Evaluation unit, computing unit 24 Data line 25 26 Data line 27 Lighting device, flash bulb 28 Layout 29 Delivery stack 30 31 Data line 32 Rotation generator 33 Input and output unit 34 Storage/memory 35 36 Connection of a company network 37 Adjusting device, control unit, regulating unit 38 39 40 41 Printing mechanism 42 Inking device 43 Cylinder, printing mechanism cylinder, form cylinder, component 41 44 Print form, print plate, flat print form, waterless flat print form 45 46 Counter pressure cylinder, transmission cylinder 47 Cylinder, printing mechanism cylinder, transmission cylinder, component 48 Packing, rubber blanket 49 Print substance, print substance web, print carrier 50 51 Print position 52 Ink supply, component 53 Roller, inking roller, component, rotation body 54 Roller, screen roller, component 55 56 Photo-electric sensor, image sensor, CCD-camera 57 Tempering unit (54) 58 Tempering unit (43) 59 Thermo-sensor 60 61 Reservoir, ink cartridge 62 Double printing mechanism, double print point 63 Heat flow for recovery 64 Utilisation, internal 65 - 66 Heat recovery 67 Energy source 68 Heat flow for recovery 69 Heat flow for recovery 70 Pump 71 Supply unit 72 Control or regulating unit, control electronic mechanism 73 Printing tower, printing unit 74 Folding apparatus 75 Control unit 76 Storage, tempering agent storage, hot water storage 77 Cooling unit, cold central unit 78 Switching valve 79 Dosage valve 80 Pump 81 Pump 82 Crossing point 83 Crossing point 84 Valve 85 Valve 86 Cooling process, process, second 87 Cooling process, process, first 88 Unit, free cooling unit 89 Compressor 42 90 Relaxing valve 91 Cooler, free cooling unit 92 Unit, logic, control 93 Cooling agent or fluid cycle 94 Heat exchanger 95 Pump 96 Heat exchanger 97 Valve, regulate-able, regulating valve, setting member 98 Valve, regulate-able, regulating valve, setting member 99 Pump 100 Computing and/or control unit 101 Fluid cycle 102 Heat exchanger 103 Valve, regulate-able, regulating valve, setting member 104 Valve, regulate-able, regulating valve, setting member 105 - 106 Part-flow 107 Part-flow 108 Part-flow 109 Part-flow 110 - 111 Part-flow 112 Part-flow 113 Storage 114 Pump 115 - 116 Feed flow 117 Feed flow 118 Thermometer 119 Fluid-gas-heat exchanger 120 - 121 Heating pump 122 Storage A Relationship, form cylinder B Relationship, screen roller Dl Ink density, actual D2 Ink density, desired F Ink type M Drive, components V Production speed 43 Ti,rated Rated temperature, desired temperature Tj,rated Rated temperature, desired temperature Kl Supply cycle, cycle K2 Supply cycle, cycle K3 Supply cycle, cycle Tl Temperature, temperature levels T2 Temperature levels T3 Temperature levels KAN Tempering cycle, cycle (M) KFZ Tempering cycle, cycle (43) KRW Tempering cycle, cycle (54) ml Measured value m2 Measured value m3 Measured value m4 Measured value m5 Measured value m6 Measured value m7 Measured value S Setting command 51 Setting command 52 Setting command 44 Claims 1.

Method as per claim 1 or 13, having the distinctive feature that the easy flow influences a separation of the printing ink between printing and non-printing areas of a print form (44). 22. Method as per claim 1 or 13, having the distinctive feature that the easy flow influences the strength of a crack when an ink-carrying cylinder (43; 47) works together with the material to be printed on (49). The invention relates to a method for adjusting the transfer of printing ink, wherein a first roller (54), which is arranged in an inker unit (42) of a printing machine, transfers printing ink to a form cylinder (43). A temperature control unit (57) enables the outer surface of the first roller (54) to reach the required temperature and/or a temperature control unit (58) enables the outer surface of the form cylinder (43) to reach the required temperature. Said temperature control unit (57) of the first roller (54) and/or the temperature control unit (58) of the form cylinder (43) can be, respectively, controlled or regulated by an adjusting device (37). specific curves or reference points for an interrelation between the production speed (V) of a printing machine and the respective required temperature on the outer surface of the form cylinder (43) or on the outer surface of the first roller (54) are stored in a storage unit (34) of the adjusting device (37) for various printing inks and/or ink types.
