Description

The invention relates to a method for printing a printing material.

Different printing processes are known that can be used in printing machines. These include, for example, those printing processes that do not have a fixed printing form. This makes it possible to design every single print product individually. As a result, personalized printed products can be produced and / or, due to the saving of printing forms, small editions of printed products can be produced at low cost. One such printing method is ink jet printing or ink jet printing. In this case, individual drops of coating agent are ejected from nozzles of print heads and transferred to a printing material in such a way that a print image is produced on the printing material. Different print images can be created by individually controlling a large number of nozzles.

An exact match of a print image on the front and back of a substrate printed on both sides is called a register (DIN 16500-2). In multi-color printing, one speaks of register (DIN 16500-2) when individual print images of different colors are put together exactly to match one image. Suitable measures must also be taken in connection with inkjet printing in order to maintain register and / or register.

Through the EP 2 202 081 A1 and the JP 2003-063707 A a printing press is known in each case, the printing press having a first printing unit and a dryer, the first printing unit having a central cylinder with its own drive motor assigned to the first central cylinder and at least one inkjet print head.

Through the DE 10 2011 076 899 A1 a printing machine is known which has at least one printing unit and at least one printhead designed as an inkjet printhead.

In inkjet printing, print heads are used, which usually each have several nozzles. Depending on the print image, for example depending on its division into color separations, different nozzles do not eject any coating agent for a longer or shorter period of time. It can happen that after a longer pause in a nozzle, this nozzle initially does not react correctly when it is next activated and, for example, ejects at least one requested drop too late or not at all. Possible causes are, for example, changes in the coating agent on contact with the ambient air in the area of the nozzle and / or changes in the nozzle itself, for example due to changes in temperatures or due to the fading of vibrations of individual components. Methods are known in which, in addition to the desired print images, predetermined maintenance print images are generated at regular intervals in order to achieve maintenance on all nozzles, that is, permanent readiness for immediate printing on request. Such maintenance print images can be, for example, strips that are printed between individual overall print images and, if necessary, are cut off from the printing material in post-processing. Through the EP 2 390 101 A2 a method is known in which, in order to maintain a print quality in an inkjet printing process, further drops are ejected in addition to the print image. It is also known to superimpose a further print image on the actual print image, for which each nozzle is activated at least once and which appears as a finely distributed dot pattern in the background of the actual print image.

In the foregoing and in the following, a printed product is to be understood in particular as a manufactured product that is both printed and optionally folded and / or cut to size. There are different types of print products, for example those that consist exclusively of a single page. In this case, for example, sheets of printing material of the appropriate size are printed or sheets of printing material are printed and then cut. Other types of printed matter consist of a plurality of individual pages that are printed on at least one common printing material, in particular at least one common printing material web, the printing material then being folded and cut, for example, in at least one folding device. Depending on the type and / or control of the at least one folding device, the individual pages must be printed in a specific arrangement on the printing material so that the individual pages are correctly oriented and in the correct sequence after folding. This specific arrangement of individual pages is called the overall print image or signature. For example, an overall print image can consist of two rows of four individual pages each, with the individual pages of a first of the two rows being oriented upside down compared to the individual pages of a second of the two rows. For example, a first overall print image is applied to the printing substrate by means of a first printing unit and a second overall printing image is applied to the printing substrate using a second printing unit, in particular on a rear side of the printing substrate.

When the printing material is transported between the first printing unit and the second printing unit, the printing material is often deformed, for example shrinking due to moisture loss as a result of an intermediate drying process and / or expansion as a result of the softening of the printing material due to the coating agent Solvent and / or water. A relative change in the corresponding dimensions of the printing material can be up to 1% (one percent), for example. This can lead to the register and / or register no longer meeting the quality requirements. Such effects could, for example, have different effects depending on the orientation of the paper fibers of the printing material in different directions, in particular less strongly in the transport direction of the printing material than in a direction transverse to this transport direction.

Through the WO 2009/005766 A2 a printing machine is known which has two printing units with print heads which are aligned on the same side of the printing material.

Through the WO 2005/031470 A1 a method is known in which toner images are generated on the basis of bitmaps and in which, due to an expected shrinkage of a printing material, these bitmaps are changed with regard to a number of image points to be printed when they are generated.

Through the DE 101 11 216 A1 There is known a method in which image data is changed to compensate for heat shrinkage, an amount of heat shrinkage having previously been experimentally obtained and corresponding data being stored in a memory.

Through the DE 10 2007 040 402 A1 a method is known in which changes in a dimension of a printing material are compensated for by an inclined position of the inkjet print heads.

Through the DE 10 2009 051 197 A1 a method is known in which rasterized image data for an inkjet printing is changed in order to compensate for web shrinkage.

Through the U.S. 4,721,969 A a method is known in which image data of a thermal printer are shifted or stretched in order to compensate for changes in a dimension of a printing material.

Through the DE 10 2006 023 113 A1 a method is known in which an endless substrate designed as a plastic profile, metal substrate, glass substrate or wood substrate is printed by means of two transfer cylinders, each of which is supplied with printing ink via several, for example six, inkjet printing units.

Through the WO 98/43206 A2 and the DE 10 2009 051 197 A1 a method for scaling a print image within raster data is disclosed in each case.

Through the US 2012/0 069 112 A1 a method is known in which a web-shaped printing material is printed by means of inkjet print heads. For this purpose, eight printing devices, which have printing heads, are arranged around a central printing cylinder, aligned radially on the latter, so that different coating agents can be applied. These printing devices are interrupted by an intermediate dryer and are thus divided into two groups.

Through the WO 2009/148468 A1 and the EP 1 031 916 A2 a method is disclosed in each case in which template image data are processed and individual pages are arranged in relation to an overall print image to be printed.

The invention is based on the object of creating a method for printing a printing material.

The object is achieved according to the invention by the features of claim 1.

One advantage of the invention is that it can preferably be avoided that areas of the printed product have to be removed after printing, for example cut off. As a result, printing material is preferably saved and a number of necessary devices and work processes are reduced. This results in particular from a preferred method for operating a printing machine, the printing machine preferably having at least one printhead with at least one first nozzle and preferably forwarding control data and / or raster data of at least one print image to be printed in the form of entries to be processed to the at least one printhead and wherein each entry is preferably assigned and / or is assigned to one of the at least one first nozzle and either has a value that corresponds to an instruction to pause, or has a value that corresponds to an instruction to eject a drop, and preferably as a function from the at least one print image assigned data by means of the at least one first nozzle at least between two drops which represent image points of the same print image to be printed and also ejected by means of this at least one first nozzle are, at least one additional drop is ejected, which does not represent a pixel of this print image to be printed.

This results preferably additionally or alternatively from a preferred method for operating a printing machine, wherein the printing machine preferably has at least one print head with at least one first nozzle and wherein preferably in at least one data memory raster data and / or control data of at least one print image to be printed in the form of to be processed Entries are and / or are stored and each entry is preferably assigned and / or is assigned to a nozzle and either has a value that corresponds to an instruction to pause, or has a value that corresponds to an instruction to eject a drop and is preferred At least one of these at least one first nozzle assigned and / or assignable first sequence of entries to be processed one after the other is checked to see whether it has at least one partial sequence which contains only entries with instructions for pausing and which contains a predetermined number of eggs When such a partial sequence is found, at least one entry of this at least one partial sequence is preferably changed in such a way that it then has a value that corresponds to an instruction to eject a drop.

Another advantage of the invention is that, preferably by specifically controlling nozzles of the at least one print head, an amount of ejected coating agent, for example ejected printing ink, is small compared to a method in which all nozzles eject coating agents at regular intervals.

Another advantage is preferably that unnecessary disturbances in a printed print image are avoided.

Raster data and / or output data and / or control data, which belong to successive print images and / or template image data, are preferably processed together and checked for corresponding sequences. As a result, even more coating agent can be saved and / or an even better print quality can be achieved.

An individual page is to be understood as meaning, for example, an object that is part of an overall print image. This can be, for example, a single page of a newspaper or a book or magazine. A single page can, however, also be a poster and be printed as the only motif on a sheet of a finished printed product. For example, a single page can also have several objects, but these are treated together when it comes to describing the overall print image. For example, an overall print image can have two individual pages that correspond to two pages of a newspaper, while at least one of these individual pages has at least one text block and at least one graphic as objects. Preferably, at least with regard to shifts that are carried out within data, an individual page is the smallest unit that remains unchanged in itself.

One advantage of the invention is preferably that the register and / or register of printed products can achieve a higher quality, in particular by, as is preferred, changes in the dimensions of a printing material being compensated for before a corresponding coating agent is applied. Another advantage is preferably that individual print jobs can be dealt with individually, as a result of which the quality of the print products can be increased further than if blanket solutions are used. Another advantage is preferably that it is easy to use for operators of the printing press, in particular due to a possible high degree of automation.

Advantageous variants of a preferred method for printing at least one printing material by means of at least one printing unit of a printing machine are described, with first output data for the production or control of at least one form of print images, in particular at least individual pixels of, preferably from, in particular, digitally stored template image data of at least one first overall print image The component of at least one first printing unit of the printing machine defining print images is generated for generating at least one first printed overall print image, and the template image data, in particular digitally stored, of the at least one first overall print image preferably have at least template image data of at least one first individual page and preferably also template image data of at least one second individual page, and preferably through a first printing process by means of the at least one first printing unit according to the first output data on the at least one first printed overall print image on which at least one printing material is generated.

The at least one first individual page and the preferred at least one second individual page within, in particular, digitally stored data are preferred while maintaining at least their respective absolute virtual page dimensions measured in a first feed direction as a function of order data related to a print order and / or as a function of Correction data stored in at least one correction memory are shifted relative to one another at least in this first reference direction. This preferably results in the advantage that printed individual pages that originate from different printing units are in register and / or register with one another in the finished printed product. The extent of the relative displacement preferably depends on how far the individual pages were previously spaced from one another. Printed individual pages that are at a greater distance from one another are moved more relative to one another, for example due to changes in the dimensions of the printing material, which is preferably compensated for by a greater relative displacement of the individual pages in the template image data.

Individual pages whose midpoints lie on top of one another, regardless of whether their page dimensions differ, are also preferably viewed as being in register. Such a difference is perceived as less annoying by the viewer than individual pages that are completely shifted to one another. Individual pages whose midpoints, as seen in the transmitted light of the printing material, lie on top of one another, regardless of whether their page dimensions differ, are also considered to be arranged in register. Such a difference is also perceived as less annoying by the viewer than individual pages that are completely shifted to one another.

The at least one first individual page in its template image data is preferably assigned at least one virtual first page dimension in a first template direction and a virtual first reference point and the at least one second individual page in its template image data has at least one virtual second reference point and more preferably also at least one virtual second page dimension in this first original direction and assigned and are a reference distance measured in a first print image direction, which the first reference point and the second reference point have to each other on the at least one first printed overall print image on the one hand and the first page dimension of a printed first individual page on the other hand in a dimension-print ratio that preferably as a function of job data related to a print job and / or as a function of correction data stored in at least one correction memory from a dimension V original ratio deviates in that a virtual reference distance measured in the first original direction, which is assigned to the virtual first reference point and the virtual second reference point to one another in the original image data of the at least one first overall print image, on the one hand, and the virtual first page dimension of the at least one first individual page in the original image data on the other hand stand to each other. This can be the case, for example, when the individual pages are simply shifted relative to one another. However, it is also possible to achieve this by a combination of shifting individual pages and stretching individual pages and / or total printed images. For example, by shifting the individual pages, their center points can be made to coincide and, in addition, their dimensions can be adjusted by individually stretching the individual pages.

Alternatively or additionally, at least one first individual page within, in particular, digitally stored data is preferred as a function of the template image data and as a function of job data related to the print job and as a function of correction data stored in at least one correction memory before and / or during the generation of the output data stretched at least in the first forward direction with a first stretching factor. By stretching at least one individual page and / or stretching, for example, an overall print image, uniform changes in the dimensions of the printing material can preferably be largely or even completely compensated for. Although this variant requires intervention in the template image data of the corresponding individual pages themselves, it achieves results of very high quality in terms of register and / or register.

The preferred method is preferably suitable on the one hand for controlling nozzles of print heads of at least one first printing unit of the printing machine, in particular for controlling an ejection of coating agent through nozzles of print heads, for example of an inkjet printing unit. Alternatively, the method is suitable for all types of digital printing processes, in particular those in which individual controlled elements generate image points, for example digital thermal printing processes, printing processes based on electrical charging, for example using a toner as a coating agent or the like. On the other hand, the method is preferably suitable for controlling at least one manufacturing device for generating solid printing forms, for example for imaging printing plates in offset printing and / or for generating printing forms for letterpress and / or flexographic printing and / or gravure printing. The method is then used to produce, in particular, solid printing forms, for example printing plates.

The at least one printing unit is preferably an inkjet printing unit and / or the printing machine is an inkjet printing machine and / or the template image data, in particular digitally stored, of the at least one first overall print image are first output data for a Control of nozzles of printheads which generates at least one first printing unit of the printing machine, according to which an ejection of coating agent is carried out through these nozzles of printheads to generate the at least one first printed overall print image and / or the respective output data are at least activation data of nozzles of printheads to be used in each case an inkjet printer of the printing machine.

In particular in connection with digital printing processes, for example inkjet printing processes, there is preferably the advantage that the data change, for example the shifting of individual pages and / or stretching of individual pages or overall print images, can be carried out relatively late, in particular only when it is already clear with which Printing machine and / or on which printing material and / or under which climatic conditions and / or with which coating agent a print job is to be carried out. If, for example, contrary to the order planning, another printing material is used, for example because a certain type of printing material is no longer available in sufficient quantities, the method can be used directly before printing begins and these changes can be taken into account. It is also possible to react to changes in ambient conditions, for example changed humidity. With digital printing processes, such changes can even be adapted in the course of a print job, be it due to changed conditions, a changed substrate during a flying roll change or based on measurements on printed products already produced within the same print job.

The displacement of at least one individual page and / or the stretching of at least one individual page and / or at least one overall print image and / or at least one reference distance depends on the template image data, at least insofar as the template image data contain information about the locations of the overall print image at which individual pages are arranged . A shift of an individual page will preferably be greater, the further away this individual page is from a reference point, for example a center line of the overall print image, in particular because the change in at least one dimension of the printing material then has the greater effect. A shrinkage of a printing substrate web would, for example, displace individual pages arranged on the edge of this printing substrate web more strongly than those individual pages which are arranged close to the center line of the printing substrate web. For this reason, the individual pages arranged at the edge must first be shifted more to compensate. This is all the more relevant the more individual pages are arranged next to one another and / or the smaller the individual pages are. With a uniform stretching of the overall print image, a uniform change in the side dimensions of the printing material can be compensated for.

As an alternative or in addition, a method for printing at least one printing material by means of at least one printing unit of a printing machine is preferred, with first output data for a production or control of at least one component defining at least one form of printing images for at least one first printing unit of the printing machine from stored template image data of at least one first overall print image Generation of at least one first printed overall print image are generated and wherein the stored template image data of the at least one first overall print image have at least template image data at least one first individual page and template image data at least one second individual page and wherein the at least one first individual page and the at least one second individual page within stored data while retaining at least their respective absolute virtual side dimensions measured in a first forward direction by a machine control ung and / or a print data processing of the printing machine itself and / or by at least one stored algorithm of the machine control and / or printing data processing of the printing machine are shifted relative to each other at least in this first template direction and whereby by a first printing process by means of the at least one first printing unit according to the first output data the at least one first printed overall print image is generated on the at least one printing material.

An advantage of a preferred, additional or alternative method for coating a printing material by means of printing units of a printing machine, wherein the printing material is coated along a transport path by means of at least one first printing unit and preferably also at least one second printing unit and where at least six different coating agents are applied to the same first side of the Printing material are applied and each of these at least six different coating agents is applied to the printing material by means of a plurality of individually controllable components of at least one first printing unit and / or at least one second printing unit of the printing machine that define individual pixels of print images as a function of output data and in particular control data and wherein, by means of the at least one first printing unit, at least three different coating agents are applied to the first side of the printing material a be applied and at least three different coating agents are applied to the first side of the printing material by means of the at least one second printing unit, there is in particular the fact that high-quality printed products can also be generated by means of controllable, in particular digitally controllable, components of at least one printing unit that define individual pixels of print images For example, they differ from simpler printed products by their variety of colors and / or by varnishes and / or others. In this way, for example, high-quality, yet individual print images can also be generated in packaging printing. This applies in particular in connection with inkjet printing units, since these can apply a large number of different coating agents in variable print images in a particularly simple manner. In particular, the individually controllable components that define individual pixels of print images as a function of output data and in particular control data are nozzles of inkjet print heads of printing units of the at least one first printing unit and / or the at least one second printing unit of the printing machine.

In particular, this also applies to a printing machine, with at least one first printing unit and at least one second printing unit preferably being arranged along a transport path through the printing machine provided for at least one printing material to be printed, and with the printing machine at least five, more preferably at least six, even more preferably at least has seven and even more preferably at least eight different intermediate stores for different coating agents and each of these at least five, more preferably at least six, even more preferably at least seven and even more preferably at least eight intermediate stores each with at least a plurality of individually controllable components of the at least one first Printing unit or the at least one second printing unit of the printing press is connected and / or connectable and preferably by means of each of these components depending on output data and in particular Ans Expensive data, individual printed pixels of printed images can be generated and each of these components is preferably arranged on the same side of the transport path through the printing machine provided for the at least one printing material to be printed, and the at least one first printing unit preferably has at least one, more preferably at least two, even more preferably at least three and even more preferably at least four of the different buffers for different coating agents and the at least one second printing unit preferably having at least one, more preferably at least two, even more preferably at least three and even more preferably at least four of the different buffers for different ones Has coating agents.

An advantage of a preferred method in which first output data and / or control data for activating the component of the at least one first and / or second printing unit, which defines at least one individual image points of print images, for generating at least one first printed unit, preferably additionally from stored template image data of at least one first overall print image Overall print image are generated and the stored template image data of the at least one first overall print image preferably have at least template image data of at least one first individual page and preferably also template image data of at least one second individual page and the at least one first individual page and the at least one second individual page preferably within stored data, preferably while retaining at least their respective absolute virtual page dimensions measured in a first feed direction as a function of job data related to a print job and / or as a function of correction data stored in at least one correction memory are shifted relative to one another at least in this first template direction and / or at least the at least one first individual page within stored data as a function of the template image data and as a function of job data related to a print job and as a function of Correction data stored in at least one correction memory is stretched before and / or during the generation of the output data at least in the first original direction with a first stretching factor, consists in particular in the fact that printing can be carried out with register and / or register, even if different printing units are used and / or the dimensions of the printing material change between the printing units, for example due to the action of a dryer.

This advantage is given in particular when, as is preferred, through the stretching of the at least one first individual page and / or the stretching of the at least one second individual page and / or the stretching of the at least one virtual reference distance and / or through the relative displacement of the at least one first individual page and at least one change in at least one dimension of the printing material is at least partially compensated for on the at least one second individual page in relation to one another in the template image data.

Another advantage arises in particular when, as is preferred, the printing material along a transport path by means of the at least a first printing unit is coated with at least one different coating agent and is then dried by means of at least one dryer and then by means of the at least one second printing unit with at least one other of the at least five, in particular at least six, more preferably at least seven and even more preferably at least eight different coating agents is coated. In particular, it can then preferably be prevented that undried coating agent contaminates the printed product and / or the printing press, and a clean and in register and / or in register print image is preferably achieved. For this purpose, at least one first printing unit and at least one first dryer and at least one second printing unit are preferably arranged along the transport path through the printing machine provided for at least one printing material to be printed.

A further advantage arises in particular when, as is preferred, at least one of the at least five, in particular at least six, more preferably at least seven and even more preferably at least eight different coating agents use a printing ink in at least one of the colors cyan and / or magenta and / or yellow and / or is black and / or is a white printing ink and / or is a transparent coating agent and / or is a coating agent of the color gold and / or silver and / or iron oxide particles and / or a positive or negative magnetic susceptibility and / or ferromagnetic or has ferrimagnetic or antiferromagnetic properties and / or is a water-based coating agent and / or has at least one organic solvent and / or can be crosslinked by means of UV light and / or is conductive and / or is only visible under UV light, because this preferably means a large number different and / or more demanding and / or forgery-proof and / or functional print images can be realized.

An alternatively or additionally applicable method is preferred for printing at least one first printing material by means of at least one printing unit of a printing machine, with output data for controlling at least one component of at least one first printing unit of the printing machine, which defines at least one form of printing images, preferably from stored template image data of at least one first overall printing image Generation of at least one first printed overall print image can be generated and wherein the at least one first overall print image is preferably specified and / or described and / or is in a primary data packet and the at least one first overall print image in the template image data and / or in the primary data packet at least one in a dimension measured in advance is assigned, and this at least one dimension is preferably compared with at least one limit value, and preferably when the at least one dimension is exceeded nzwerts by the at least one dimension, the at least one first overall print image based on this original direction is divided into a plurality of sections of the at least one first overall print image and the plurality of sections is preferably defined and / or described and / or is in a plurality of secondary data packets and preferably by printing processes that are preferably carried out by means of the at least one first printing unit and in which output data based on at least one of the secondary data packets are processed, preferably the plurality of sections of the at least one first overall print image is generated on the at least one first printing substrate .

One advantage of this preferred method is, in particular, that a relatively small memory can be used for the secondary data packets and / or that particularly large print images and, in principle, also printed print images that extend endlessly in at least one direction can be created that originate from a digital print image template . Without the division of the data, there would be a limitation, for example, by a memory that stores raster data, for example, which are then retrieved from this memory and converted into output data. By dividing data packets into large data packets for this memory, print images that are printed for a very long time are preferably of high quality. The preferred use of a buffer and / or ring memory and / or shift register enables complete printing even at high printing speeds because fewer large data memories have to be emptied and refilled. In particular, emptying and / or filling the corresponding data memory can thereby be decoupled from reading out this data memory. If, as is preferred, the division of a primary data packet into several secondary data packets is only carried out when a limit value is exceeded and / or by a machine control and / or print data processing and / or an algorithm stored therein, it is particularly flexible to work because, for example, a print shop with differently configured Printing presses does not have to determine in advance which printing press is to be used and consequently in which way the data packets are to be divided. In particular, if each printing press has, for example, its own, configuration-dependent at least one limit value, unnecessary effort in data processing can be avoided.

In particular, if the primary data packet has template image data or geometrically modified template image data, sections can preferably first be created therefrom, which can then be converted into raster data or geometrically modified raster data. As a result, the rasterization process can preferably be carried out with relatively small data packets in each case. This facilitates data handling during rasterization and allows very large print images to be printed.

It is also possible to use at least one heating element per nozzle which generates a gas bubble in a volume filled with coating agent at high speed by evaporating the coating agent. The additional volume of the gas bubble displaces the coating agent, which in turn is ejected through the corresponding nozzle and forms at least one drop of coating agent.

In the case of the drop-on-demand process, a drop deflection after it has been ejected from the corresponding nozzle is not necessary, since it is possible to set a target position of the respective coating agent drop on the moving substrate web 02 with respect to the circumferential direction of the at least one first central cylinder 201 solely by an emission time of the respective coating agent droplet and a rotation speed of the first central cylinder 201 and / or by the rotational position of the first central cylinder 201 to be determined.

This takes place as a function of the speed of rotation and / or the angular position of the at least one first central cylinder 201 , a distance between the respective nozzle and the substrate web 02 as well as the position of the target area of the respective nozzle with respect to the circumferential angle. This results in a desired print image that is designed as a function of the activation of all nozzles.

A plurality of partial image planes are further preferred for each printing ink to be printed 632 in the form of several different color extracts 629 mutually different, generated within respective color separations of the same printing ink, with a number n of these sub-image planes 632 per printing color is preferably equal to a number n of the different drop sizes that are generated by means of each print head 212 ; 412 are producible. This number n is preferably at least three. Every drawing plane 632 then contains information about the exact positions at which a pixel of the respective color and size is to be printed. For example, by superimposing the sub-picture planes 632 a printing color, the color separation and / or the partial image of this printing color is generated. By overlaying all color separations 629 and / or partial images result in the entire print image. The sub-image planes are preferred 632 of a printing color and then stored as a partial image of this printing color. The drawing files and the drawing planes 632 are also raster data 647 called.

Every entry 631 can take on a value from a number of n + 1 (n plus one) default values. Preferably each entry has 631 either a value which corresponds to an instruction to pause, or a value which corresponds to an instruction to eject a drop and, more preferably, a drop size assigned to this drop. Each of these n + 1 (n plus one) default values preferably corresponds to a drop size or the information that no image point is to be generated at this point, that is, no printing ink is to be ejected. For example, these default values can be displayed in a two-bit representation "00" for "no printing color" or " 01 ”For a“ small ”pixel or drop or“ 10 ”for a“ medium ”pixel or drop or“ 11 ”for a“ large ”pixel or drop. Any such column 633 preferably contains at least a first sequence 633 from several entries 631 , with each entry first 631 this at least a first episode 633 either has a value which corresponds to an instruction to pause, or has a value which corresponds to an instruction to eject a drop and a drop size assigned to this drop.

Any sub-image matrix is preferred 629 each printing color is stored and / or processable in such a way that each nozzle of the print heads assigned to this printing color 212 ; 412 prefers exactly one column 633 of the partial image is assigned and / or is. This column 633 then contains entries in different lines 631 which each have one of the corresponding default values and thus cause the corresponding nozzle to eject printing ink at relevant times. By processing entire lines of the corresponding partial image matrix in a timed manner 629 through the nozzles of the corresponding at least one printhead 212 ; 412 is created on the substrate 02 preferably the print image to be generated in the form of superimposed matrix-like patterns of image points, preferably of different printing colors. A time-synchronized processing is to be understood in particular to mean the case in which the nozzles are at different points with regard to the transport path of the printing material 02 are arranged and therefore, for example, do not eject printing ink at the same time when a straight line is to be generated which is oriented orthogonally to the transport direction.

Which is preferably in at least one data memory 601 ; 602 and more preferably in the at least one raster data memory 602 stored partial images, in particular partial image matrices 629 and / or raster data 647 are preferably via the at least one second data line 613 to the at least one data mapping 604 transmitted. The at least one data mapping 604 is preferred with a number of printheads 212 ; 412 connected, which together have a plurality of nozzles.

For example, this is at least one data assignment 604 with all printheads 212 ; 412 the respective pressure unit 200 ; 400 connected, which are assigned to a specific printing ink and / or for the ejection of the printing ink for an entire color separation 629 are provided. The at least one data mapping 604 orders each column preferentially 633 of the color separation available to him 629 , so in particular the partial image matrix available to him 629 of the raster data 647 at least one and more preferably exactly one nozzle of a print head 212 ; 412 to. In this way, a layer of a print image to be printed is on the printing material 02 with respect to a direction A. across the intended transport path of the printing material 02 and / or with respect to the axial direction A. set. Should the print image to be printed be in relation to this direction A. can be changed in its position, this is done, for example, by shifting assignments between the columns 633 of the sub-image matrices 629 to the nozzles of the printheads 212 ; 412 realized. The raster data are and / or are preferred 647 i.e. in the form of entries to be processed 631 deposited, especially in the form of sequences of entries 631 that have to be processed with the respective nozzles. The at least one data mapping 604 preferably assigns a sequence of entries to be processed by each nozzle 631 to.

In the printing mode, points in time at which the respective lines of the partial image matrix representing the partial image 629 are processed, preferably in interaction with the speed of rotation and the angular position of the respective central cylinder 201 ; 401 and / or the respective drive motor 208 ; 408 determined with which the print head printing this partial image 212 ; 412 cooperates. Both the position and the dimensions of the print image to be generated and / or the printed image on the printing material 02 in a direction parallel to the intended transport path for the printing material 02 and / or in the circumferential direction of the at least one central cylinder 201 ; 401 are influenced and / or can be influenced by the respective times at which the corresponding nozzles eject their coating agent droplets and through the angular position and / or rotation speed of the corresponding central cylinder 201 ; 401 at this point in time and / or by a relative position of the printing material 02 on the corresponding central cylinder 201 ; 401 at this time. Therefore it processes at least one data mapping 604 preferably both the respective raster data 647 , as well as from the at least one signal source 617 ; 618 for characterizing an angular position, in particular at least one central cylinder 201 ; 401 data made available when calculating conditions, in particular times at which the nozzles have at least one data assignment to them 604 connected print heads 212 ; 412 Have to expel coating agents. At least the at least one data mapping 604 the at least one second printing unit 400 and more preferably also the at least one data assignment 604 the at least one first printing unit 200 preferably additionally processes those from the at least one register sensor 619 information made available directly or indirectly in order to enable printing in register and / or in register, for example when printing on the front side of the printing material 02 by means of the first printing unit 200 and printing on the reverse side of the printing material 02 by means of the second printing unit 400 or when printing on the same side of the substrate 02 both with the first printing unit 200 as well as with the second printing unit 400 .

For example in a case in which per printing unit 200 ; 400 several rows and in particular several double rows of printheads 212 ; 412 are used per printing color are preferred by the at least one data allocation 604 the columns 633 of the respective color separations 629 and in particular the sub-image matrices 629 especially in the axial direction A. related in turn to the nozzles of the printheads 212 ; 412 assigned, regardless of the arrangement of the nozzles with respect to the transport direction of the printing material 02 and / or the circumferential direction of the respective central cylinder 201 ; 401 . Again, this arrangement only plays a role in determining the correct point in time for ejecting the coating agent. Especially in the case of two double rows of printheads 212 ; 412 per pressure unit 200 ; 400 and the columns are for each printing color 633 the respective sub-image matrix 629 preferably alternately to a corresponding nozzle of a print head 212 ; 412 a first of the two double rows of printheads 212 ; 412 and a corresponding nozzle of a print head 212 ; 412 a second of the two double rows of printheads 212 ; 412 assigned. This assignment can, for example, be an alternative to the at least one data assignment 604 also by means of the at least one raster data computer 612 respectively. The partial print image or the color separation is therefore column-wise on two double rows of print heads 212 ; 412 divided and only through the application of printing ink on the substrate 02 reassembled.

This preferably allows at least one input device 608 an operator can directly influence an ejection of coating agent through the nozzles of such print heads 212 ; 412 attached to the same data mapping 604 are connected, like at least one input device 608 .

This means that, for example, the changed entries 631 in the color separation 629 and / or represent a predetermined pattern in the print image. This specification is preferably a specification that is binding for all nozzles of a printing ink and more preferably for all nozzles of all printing inks. In this way, a fixed and tested pattern can be used, which is known to not or only minimally disturb the overall optical impression of a printed image.

Such second episodes are also preferred 633 of entries 631 takes into account the consequences to be changed 631 are adjacent or are at least arranged in their vicinity, independently whether these second sequences are changed by the filling algorithm or not.

Alternatively, the method is suitable for all types of digital printing processes, in particular those in which individual controlled elements generate image points, for example digital thermal printing processes, printing processes based on electrical charging, for example using a toner as a coating agent or the like. On the other hand, the method is preferably suitable for controlling at least one manufacturing device for generating solid printing forms, for example for imaging printing plates in offset printing or generating printing forms for letterpress and / or flexographic printing and / or gravure printing.

An example of such data for at least one print image to be applied is an area coverage, that is to say a quantity of printing ink per area, which, for example, influences the change in the at least one dimensions of the printing material 02 may have. Examples of such data for at least one print image to be applied are a format which the printed product should have and / or a number and / or sequence of pages which the print product should have.

The order data preferably also depend on the at least one post-processing device 500 especially because this defines certain boundary conditions, such as the order of the individual pages 638 ; 639 ; 1638 ; 1639 within the overall print image 636 ; 637 .

On the other hand, there can be shifts and / or stretching of the individual pages 638 ; 639 ; 1638 ; 1639 after the page placeholders have been supplemented and / or replaced with these. Mixtures are also possible, for example a shift of the page placeholders in combination with a stretching already through the information of the actual print images of the individual pages 638 ; 639 ; 1638 ; 1639 supplemented and / or replaced individual pages 638 ; 639 ; 1638 ; 1639 . It is also possible to first apply the process to the raster data that has already been generated 647 apply, which are in the form of matrices of pixels.

The order data are preferably processed further, for example by means of at least one control instance 677 and preferably at least partially together with the template image data 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 of the print job. The at least one supervisory authority takes effect 677 preferably to at least one correction memory 666 to, in which correction data is stored. Such correction data relate, for example, to empirically generated compensation instructions which, depending on the order data, are each suitable for the greatest possible compensation for expected changes in the dimensions of the printing material 02 to lead.

In particular, the displacement and / or stretching of the individual pages is preferred 638 ; 639 ; 1638 ; 1639 by means of the at least one geometry module 678 accomplished. Initially, geometrically modified template image data are preferred 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 generated, which in the further course the basis for the production of raster data 647 and / or output data 646 , especially control data 646 form.

In a first preferred further processing of this type, in particular by means of the at least one geometry module 678 as preferred, the individual pages are first 638 ; 639 ; 1638 ; 1639 in the form of page placeholders within the document template and / or the basic structure of the respective overall print image 636 ; 637 generated and / or treated and / or on the basis of the order data and the correction data position and shape of these page placeholders within the document template and / or the basic structure of the respective overall print image 636 ; 637 and then these page placeholders with information, in particular print image data of the actual print images of the individual pages 638 ; 639 ; 1638 ; 1639 filled with the respective print image of the individual pages 638 ; 639 ; 1638 ; 1639 represent. For the purposes of this method, these page placeholders therefore preferably initially represent the respective individual pages 638 ; 639 ; 1638 ; 1639 represent and thus preferably represent this document template and / or this basic structure of the respective overall print image 636 ; 637 with the page placeholders arranged therein, the stored data, in particular template image data 641 ; 642 of the respective overall print image 636 ; 637 Such a page placeholder can, for example, have the shape of an empty rectangle.

A change in a dimension of the printing material then preferably takes place 02 , for example by the action of at least one dryer 301 onto the substrate 02 . Thereafter, it is preferred to eject coating agent through nozzles of print heads 212 ; 412 at least one other printing unit 211 ; 411 especially inkjet printer 411 the second printing unit 400 the printing press 01 the at least one printed second overall print image 637 generated. Shifting the individual pages is preferred 638 ; 639 of the at least one first overall print image 636 for example, the change in the at least one dimension of the printing material that is to be expected or, if applicable, has already taken place 02 matched that after the application of the at least one first overall print image 636 by means of the first printing unit 200 and after changing the at least one dimension of the printing material 02 and after the application of the at least one second overall print image 637 by means of the second printing unit 400 at least one and preferably each of the first total printed image 636 associated single page 638 ; 639 In register and / or in register with one of the second printing unit 411 printed single page 1638 ; 1639 on the substrate 02 is arranged. Such an arrangement in accordance with register and / or in accordance with register is given in particular in the case in which the at least one, and preferably each, the first overall print image 636 associated single page 638 ; 639 with its center point on a center point of another individual page arranged on the other or the same side of the printing material 1638 ; 1639 which is the second overall print image 637 listened to.

By changing the at least one dimension of the printing material 02 at least one side dimension also changes 648 ; 649 of the individual pages that have already been printed 638 ; 639 . The virtual side dimensions are preferably correct 663 ; 664 the Single pages 638 ; 639 of the first overall print image 636 with the virtual page dimensions 1663 ; 1664 of the individual pages 1638 ; 1639 of the second overall print image 637 match. For the first variant of the method, this inevitably results in the situation that side dimensions 648 ; 649 of the printed individual pages 638 ; 639 of the first overall print image 636 of side dimensions 1648 ; 1649 of printed single pages 1638 ; 1639 of the second overall print image 637 differ, in particular due to the change in the at least one dimension of the printing material 02 . However, this is permissible and less disturbing than a shift of the printed pages to one another, i.e. a misregistration and / or a register error. This deviation can be accepted, for example, if it is dispensed with in the template image data 643 ; 644 ; 1643 ; 1644 of the individual pages 638 ; 639 ; 1638 ; 1639 to intervene too strongly. On the one hand, this saves computational effort, and on the other hand, the template image data of the 643 remains; 644; 1643; 1644 of the single pages 638 ; 639 ; 1638 ; 1639 Preserved true to the original except for their shifts.

The virtual reference points preferably have 654 ; 656 in the template image data 641 of the first overall print image 636 Before the shift, first an in particular virtual template offset 667 on. Due to the shift, the virtual reference points point 654 ; 656 then an especially virtual output offset 668 which is still a virtual length and, for example, in the raster data 647 is available. The corresponding reference points point directly after printing by the first printing unit 651 ; 652 of the printed individual pages 638 ; 639 a first, in particular wet, printing offset 669 in the corresponding print image direction C. on. This first misalignment 669 is changed, for example, after drying, in particular reduced to a second, in particular dry print offset 671 . This is followed by the second overall print image 637 by the second printing unit 400 applied, with their individual pages 1638 ; 1639 and especially reference points 1651 ; 1652 Immediately after application, a third, in particular also wet, print offset 672 have, which is preferably just as large as the second, dry printing offset 671 the reference points 651 ; 652 of the printed individual pages 638 ; 639 of the first overall print image 636 . The following possible changes to the at least one dimensions of the printing material 02 concern the first overall print image 636 and the second total print image 637 to the same extent and therefore have no influence on register and / or register.

Preference is given to converting the template image data 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 in output data 646 processed at least two processes. One of these at least two preferred processes is the shifting of the individual pages 638 ; 639 of the first overall print image 636 to each other. Another of these at least two preferred processes is the creation of raster data 647 . The individual pages are preferably shifted first 638 ; 639 of the first overall print image 636 to each other, with geometrically modified template image data 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 raster data are created and then carried out 647 from the geometrically modified template image data 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 . The raster data 647 are then the basis of the output data 646 or identical to the output data 646 . Alternatively, raster data is first created 647 from the template image data 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 and then the individual pages are shifted 638 ; 639 of the first overall print image 636 to each other within the raster data 647 , with geometrically modified raster data 647 develop. The geometrically modified raster data 647 are then the basis of the output data 646 or identical to the output data 646 , depending on whether the raster data 647 can be further processed directly or a further modification of the raster data for the control of the nozzles 647 is necessary and / or desired. As an alternative or in addition, the individual pages can be shifted 638 ; 639 of the first overall print image 636 to each other and the creation of raster data 647 at least partially simultaneously and / or alternately, for example by creating raster data line by line and / or column by column 647 and shifting parts of the individual pages in between 638 ; 639 .

In a second variant of the method, with which the print quality can be increased with regard to register and / or register, the at least one first overall print image is preferred 636 changed in such a way that the at least one first individual page 638 and the at least one second individual page 639 preferably in stored form within this at least one first overall print image 636 at least in a first forward direction B. be stretched. The at least one first individual page is preferred 638 and the at least one second individual page 639 in the first original direction B. subjected to a one-dimensional centric stretching, more preferably with a common stretching center 674 . The particular common stretch center 674 lies in a center line, for example 673 of the at least one first overall print image 636 . It is also possible to use other extension centers, but for reasons of symmetry the center line 673 preferred. With a corresponding stretching of the at least one first overall print image 636 and / or the individual pages 638 ; 639 within the at least one first overall print image 636 even before this at least one first overall print image is applied 636 on the substrate 02 636 can be a change in the at least one dimension of the printing material following the printing process 02 preferably be fully balanced. Thus, for example, there can be a shrinkage of the printing material 02 due to a drying process, must be compensated for before the print image is applied. The finished print product has printed individual pages 638 ; 639 in the intended size. The at least one stretching takes place preferably only after the template image data have been completed 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 , i.e. only after no operator has direct access to the image data.

A stretching is preferably to be understood as a stretching in the mathematical sense which can lead to an enlargement or, in particular, to a reduction in the case of a stretching factor between zero and one. In the foregoing and in the following, the term scaling is therefore also used for this stretching in the mathematical sense in order to further clarify the possibility of enlarging and reducing.

The second variant relates to a method for printing at least one printing material 02 , in particular at least one printing substrate web 02 , by means of at least one printing unit 211 ; 411 the printing press 01 , wherein from template image data stored in particular in digital form 641 ; 642 ; 643 ; 644 at least a first overall print image 636 first output data 646 for producing or controlling at least one component of at least one first printing unit that defines at least one form of print images, in particular at least individual pixels of print images 200 the printing press 01 for generating at least one first printed overall print image 636 are generated and the stored template image data 641 ; 642 ; 643 ; 644 at least the at least one first overall print image 636 at least template image data 643 at least a first single page 638 have and wherein at least the at least one first individual page 638 within stored data depending on the template image data 641 ; 642 ; 643 ; 644 and / or as a function of job data related to a print job and / or as a function of in at least one correction memory 666 stored correction data before and / or during the generation of the output data 646 at least in one forward direction B. ; D. , especially the first direction B. is stretched with a stretching factor, in particular a first stretching factor, and wherein by means of a first printing process by means of the at least one first printing unit 200 according to the first output data 646 the at least one first printed overall print image 636 on at least one substrate 02 is produced.

Preference is given to converting the template image data 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 in output data 646 processed at least two processes. One of these at least two preferred processes is the stretching of the individual pages 638 ; 639 and / or the first overall print image 636 . Another of these at least two preferred processes is the creation of raster data 647 . The individual pages are preferably stretched first 638 ; 639 and / or the first total print image 636 , with geometrically modified template image data 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 raster data are created and then carried out 647 from the geometrically modified template image data 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 . The raster data 647 are then the basis of the output data 646 or identical to the output data 646 . Alternatively, raster data is first created 647 from the template image data 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 and then the individual pages are stretched 638 ; 639 and / or the first overall print image 636 within the raster data 647 , with geometrically modified raster data 647 develop. The geometrically modified raster data 647 are then the basis of the output data 646 or identical to the output data 646 , depending on whether the raster data 647 can be further processed directly or a further modification of the raster data for the control of the nozzles 647 is necessary and / or desired. As an alternative or in addition, the individual pages are stretched 638 ; 639 and / or the first overall print image 636 and the creation of raster data 647 at least partially simultaneously and / or alternately, for example by creating raster data line by line and / or column by column 647 and stretching of parts of the individual pages in between 638 ; 639 and / or the first overall print image 636 .

The single pages are preferred 638 ; 639 and / or the at least one first overall print image 636 preferably in stored form within this at least one first overall print image 636 stretched. This is preferably done only after the template image data has been completed 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 , i.e. only after no operator has direct access to the image data.

A preferred third variant of the preferred method is a combination of the first variant of the method and the second variant of the method. In particular, the preferred third variant of the method thus contains all features of the first variant of the method and all features of the second variant of the method, as long as there are no contradictions. For example, the individual pages 638 ; 639 within the template image data 641 ; 642 ; 643 ; 644 shifted to each other and each stretched centrically from its own center of elongation 374, which is preferably on a center line of the respective shifted individual page 638 ; 639 or it will be, for example, the individual pages 638 ; 639 stretched together and then shifted towards each other. The third variant is of interest, for example, when the printing material 02 its dimensions are changed to different degrees in different places, for example because in the area of the individual pages 638 ; 639 the application of coating agent changes the at least one dimension other than in the area outside the individual pages 638 ; 639 , especially in edge areas and / or spaces. The at least one first individual page is then preferred 638 and the at least one second individual page 639 before and / or after the stretching within stored data while maintaining at least their respective in a first presentation direction B. measured absolute side dimension 648 ; 649 relative to one another at least in this first forward direction B. postponed.

Ratios, in particular the dimension ratio and / or the dimension-print ratio and / or the dimension-original ratio and / or the total printed image-print ratio and / or the total printed image-original ratio are preferably to be understood as ratios in the mathematical sense.

Page description data are preferably vector-based data. A shift of a single page 638 ; 639 ; 1638 ; 1639 Within page description data, for example, all objects belonging to this individual page can remain unchanged, with the exception of a position vector which defines their position, in particular their position on the overall print image 636 ; 637 . A stretch of a single page 638 ; 639 ; 1638 ; 1639 and / or an overall print image 636 ; 637 can be implemented, for example, that all objects on this single page 638 ; 639 ; 1638 ; 1639 and / or all objects and / or individual pages 638 ; 639 ; 1638 ; 1639 this overall print image 636 ; 637 be stretched in itself, as well as experience a stretching of the respective position vector that defines their position.

By means of the at least one second printing unit 400 the printing press 01 a different side of the substrate is preferred 02 printed than by means of the at least one first printing unit 200 the printing press 01 . Alternatively and further preferred, however, is by means of the at least one second printing unit 400 the printing press 01 the same side of the substrate 02 printed, as by means of the at least one first printing unit 200 .

If the at least one limit value is exceeded by the at least one dimension of the at least one overall print image, it is preferred 636 ; 637 , especially the first overall print image 636 the at least one overall print image 636 ; 637 , especially first overall print image 636 especially on the forward direction B. , D. related in a plurality of sections 679 of the at least one overall print image 636 ; 637 , in particular the first overall print image 63 divided.

The sections 679 then preferably each have dimensions in the in particular second forward direction D. on that the in particular do not exceed the second limit value. The sections 679 preferably optionally have dimensions in the first forward direction B. that do not exceed the first limit value. Preferably, there are several resulting sections 679 of the at least one overall print image 636 ; 637 , especially the first overall print image 636 Dimensions in the template direction B. , D. , especially the first direction B. and / or second forward direction D. which are the same, more preferably the same as the respective, in particular the first and / or the second limit value. For example, all have sections 679 in the first original direction B. or the second original direction D. same dimensions except for a first or a last section 679 , the dimension of which results from a remainder left over from the division. The sections preferably have 679 in each case a width that corresponds to the width of the at least one overall print image 636 ; 637 corresponds to and / or assign the sections 679 each has a length that results from a maximum processable size of secondary data packets.

The plurality of sections is and / or is preferred 679 set and / or describe in a plurality of secondary, in particular separate and / or different data packets. The respective secondary data packets are preferably smaller than the primary data packet, in particular related to a necessary storage space. As a result, the secondary data packets can be further processed with relatively limited resources, even if they would not be able to further process the primary data packet. Each secondary data packet preferably only has data that has exactly one section 679 of the at least one overall print image 636 ; 637 , especially the first overall print image 636 affect. All one section is preferred 679 of the at least one overall print image 636 ; 637 , especially the first overall print image 636 relevant data in exactly one secondary data packet. More preferably, therefore, each secondary data packet corresponds in each case to exactly one section 679 of the at least one overall print image 636 ; 637 , especially the first overall print image 636 .

It is preferred by means of the at least one first printing unit 200 executed printing processes in which output data is based in each case on at least one of the secondary data packets 646 are processed, the plurality of sections 679 of the at least one overall print image 636 ; 637 , especially the first overall print image 636 and thereby preferably the at least one printed overall print image 636 ; 637 , especially first printed complete print image 636 on the at least one first printing material 02 generated, more preferably generated without gaps. In the printing processes, output data based on at least one and more preferably on exactly one of the secondary data packets are preferred 646 processed. These printing processes are preferred at least partially in succession by means of the at least one first printing unit 200 executed. This is to be understood in particular as the fact that printing processes which begin first are preferably also ended first. However, there may be overlaps, in particular if nozzles of print heads are arranged at different points along the transport path and nozzles arranged further forward with regard to the transport path already have a subsequent section 679 print, while nozzles arranged further back with respect to the transport path still have a previous section 679 Press. A gapless generation is to be understood as meaning that the printed overall print image 636 ; 637 , in particular the first printed overall print image 636 it cannot be seen at which point sections 679 adjoin each other.

Depending on whether the division into secondary data packets takes place before or after the print image data has been rasterized and / or stretched and / or shifted, the print image data within the secondary data packets are preferably at least initially, for example, in the form of at least one vector-based page description, for example as a PDF.

The primary data packet preferably has the template image data 641 ; 642 ; 643 ; 644 or geometrically modified template image data 641 ; 642 ; 643 ; 644 or raster data 647 or geometrically modified raster data 647 on. The secondary data packets preferably each have template image data 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 or geometrically modified template image data 641 ; 642 ; 643 ; 644 or raster data 647 or geometrically modified raster data 647 on, more preferably just like the primary data packet.

The data contained in the secondary data packets are preferred by means of at least one raster graphics processor 603 processed. The resulting packets of raster data are preferred 647 directly or indirectly, for example via at least one geometric modification, in particular stretching and / or displacement, the output data 646 generated. In particular, packets of raster data based in each case on different secondary data packets are preferred 647 at least partially in succession to Generation of output data 646 for printed sections 679 of the at least one overall print image 636 ; 637 , especially the first overall print image 637 used. The secondary data packets and / or raster data obtained therefrom are preferred 647 processed in succession to output data 646 to generate, according to which the print image is generated, more preferably according to which coating agent is ejected from nozzles. The output data 646 as described, preferably on the nozzles of the print heads 212 ; 412 distributed. Alternatively, it is also possible to first use the template image data 641 ; 642 ; 643 ; 644 ; 1643 ; 1644 if necessary to subject a shift and / to the stretching and in any case first in raster data 647 and to make the division into sections only on the basis of the raster data 647. However, this requires higher computing capacities and / or storage capacities in connection with the at least one raster graphics processor 603 .

The secondary data packets are preferably stored at least partially one after the other in at least one memory, more preferably less memory than sections 679 and even more preferably exactly one memory is loaded.

The secondary data packets are preferably at least partially consecutively from at least one memory, more preferably fewer memories than sections 679 and even more preferably read out from exactly one memory. Such a memory is in turn, for example, the at least one image data memory 601 and / or the at least one raster data memory 602 . The secondary data packets are preferably converted into output data at least partially one after the other 646 processed. In these contexts, “at least partially one after the other” preferably means that a corresponding treatment of a first secondary data packet has already been completed before the same corresponding treatment of a last secondary data packet originating from the same primary data packet is started.

The secondary data packets and / or packets from raster loads based in each case on different secondary data packets are preferred 647 each stored as a whole in at least one memory, in particular a buffer and / or ring memory and / or shift register, and more preferably read out from there at least partially one after the other. For example, at least one second secondary data packet is already stored in the at least one memory, while at least one previous first secondary data packet is still being read out. For example, at least a third secondary data packet is already stored in the at least one memory, while the at least one previous second secondary data packet is still being read out or has not yet been read out. In this way it is preferably ensured that a continuous flow of output data 646 from raster data 647 can be created even if the memory were insufficient to hold the raster data 647 to save if the entire primary data packet should be saved and / or processed at once. In particular, it is preferably ensured in this way that a continuous flow of output data 646 from raster data 647 can be created even if the raster data 647 can be loaded into the appropriate memory in packets and deleted from it again. Such a memory is, for example, the at least one image data memory 601 and / or the at least one raster data memory 602 .

The sections are preferred 679 and thus also the secondary data packets already generated before data is sent to the at least one first printing unit 200 and de at least one second printing unit 400 be divided. When using two printing units 200 ; 400 a synchronization is preferably carried out at regular or irregular intervals, more preferably only between such output data 646 that are based on secondary data packets from different primary data packets. A processing of output data 646 which are based on secondary data packets of the same primary data packet, is preferably not influenced and / or interrupted for synchronizations.

The division of the at least one overall print image 636 ; 637 , especially the first overall print image 636 on several sections and thus the creation of the secondary data packets is preferably carried out by means of the at least one image data computer 611 and / or by means of the at least one raster data computer 612 and / or by means of another computer, for example another computer in the printing press 01 and / or the machine control 600 and / or print data processing 600 .
