Description

  • The invention relates to a method for printing a printing substrate and a printing press.
  • Various printing methods are known which can be used in printing presses. These include, for example, those printing processes which do not have a fixed printing form. This makes it possible to customize each individual printed product. As a result, personalized printed products can be produced and / or small print runs of printed products can be produced at low cost due to the saving of the printing forms. One such printing method is ink jet printing or ink jet printing. In this case, individual coating agent drops are ejected from nozzles of printheads and transferred to a substrate in such a way that a printed image results on the substrate. By individual control of a plurality of nozzles so different print images can be created.
  • An exact match of a print image on front and back of a double-sided substrate is called register ( DIN 16500-2 ). In multicolor printing one speaks of the passer ( DIN 16500-2 ), when individual print images of different colors are matched exactly to a picture. Also in the context of inkjet printing, appropriate measures must be taken to maintain register and / or register.
  • By the EP 2 202 081 A1 and the JP 2003-063707 A In each case, a printing press is known, wherein the printing press has a first printing unit and a dryer, wherein the first printing unit has a central cylinder with its own, the first central cylinder associated drive motor and at least one ink jet print head.
  • By the DE 10 2011 076 899 A1 a printing machine is known which has at least one printing unit and at least one print head designed as an inkjet printhead.
  • In ink jet printing printheads are used, which usually each have a plurality of nozzles. Depending on the printed image, for example, depending on its division into separations, different nozzles eject more or less long no coating agent. It may happen that after a long break of a nozzle, this nozzle initially does not react correctly at its next activation 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 upon 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 decay of vibrations of individual components. Methods are known in which, in addition to desired print images, predetermined maintenance print images are generated at regular intervals in order to achieve maintenance at all nozzles, ie a permanent readiness for immediate printing on request. Such maintenance print images can be, for example, strips which are printed between individual complete print images and, if appropriate, are cut off from the printing material in a post-processing. By the EP 2 390 101 A2 For example, a method is known in which, in order to maintain print quality in an ink jet printing process, additional drops are ejected in addition to the printed image. It is also known to superimpose on the actual print image another print image for which each nozzle is driven at least once and which appears as a finely distributed dot pattern in the background of the actual print image.
  • By a printed product is to be understood in the foregoing and hereinafter in particular a finished product which is both printed and optionally folded and / or cut to size. There are different types of printed products, for example those that consist exclusively of a single page. In this case, for example, printing material sheet printed appropriate size or printed substrate webs and then cut. Other types of printed products consist of a plurality of individual pages, which are printed on at least one common substrate, in particular at least one common substrate web, wherein the substrate is subsequently 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 substrate, so that after folding a correct orientation and order of the individual pages is guaranteed. This specific arrangement of single pages is called the total print image or signature. For example, a total print image may consist of two rows of four individual pages, wherein, for example, the individual pages of a first of the two rows are oriented upside down in comparison to the individual pages of a second of the two rows. For example, a first complete print image is applied to the substrate by means of a first printing unit, and a second overall printed image is suitably applied to the substrate by means of a second printing unit, in particular matching on a back side of the printing material.
  • In the case of transport of the printing material between the first printing unit and the second printing unit, deformation of the printing material often occurs, for example, shrinkage due to moisture loss due to an intermediate drying process and / or stretching due to softening of the printing substrate by the coating agent Solvent and / or water. For example, a relative change in the appropriate size of the substrate may be up to 1% (one percent). This may result in the Passer and / or Register no longer meeting the quality requirements. Such effects could, for example, depending on the orientation of paper fibers of the printing material in different directions have different effects, especially in the transport direction of the substrate less strong than in a direction transverse to this transport direction.
  • By the WO 2009/005766 A2 For example, a printing machine is known which has two printing units with print heads which are aligned on the same side of the printing material.
  • By the WO 2005/031470 A1 For example, 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 as they are generated with respect to a number of pixels to be printed.
  • By the DE 101 11 216 A1 For example, a method is known in which image data is changed to compensate for heat shrinkage, wherein an amount of heat shrinkage has previously been experimentally obtained and corresponding data is stored in a memory.
  • By the DE 10 2007 040 402 A1 For example, a method is known in which changes in a dimension of a substrate are compensated for by an inclination of inkjet printheads.
  • By the DE 10 2009 051 197 A1 For example, a method is known in which rasterized image data for inkjet printing is changed to compensate for web shrinkage.
  • By the US 4,721,969 For example, a method is known in which image data of a thermal printer is translated or stretched to compensate for changes in a dimension of a substrate.
  • The invention has for its object to provide a method for printing a substrate and a printing press.
  • The object is achieved by the features of claim 1 and the features of claim 12.
  • An advantage of the invention is preferably that it can be preferably avoided that areas of the printed product must 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 press, wherein the printing machine preferably has at least one print head with at least one first nozzle and preferably forwarding control data and / or raster data of at least one print image to be processed to the at least one print head in the form of entries to be processed and preferably wherein each entry is respectively assigned to one of the at least one first nozzle and / or and has either a value corresponding to an instruction for pausing or a value corresponding to an instruction for ejecting a drop, and preferably depending data associated with the at least one printed image by means of the at least one first nozzle at least between two drops, which represent pixels of a same printed image to be printed and are also ejected by means of this at least one first nozzle, at least one additional I drop is ejected, which represents no pixel of this print image to be printed.
  • This preferably results additionally or alternatively from a preferred method for operating a printing press, the printing machine preferably having at least one print head with at least one first nozzle and preferably raster data and / or control data of at least one print image to be processed in the form of at least one data memory And each entry is associated with a nozzle and / or becomes and either has a value that corresponds to a statement for pausing, or has a value that corresponds to a statement for ejecting a drop and preferred at least one of these at least one first nozzle associated and / or assignable first sequence of successively processed entries is checked to see if it has at least one subsequence containing only entries with instructions for pausing and a predetermined A In the case of finding such a subsequence, at least one entry of this at least one subsequence is preferably changed such that it subsequently has a value which corresponds to an instruction for ejecting a drop.
  • A further advantage of the invention is preferably that, by selectively controlling nozzles of the at least one print head, an amount of ejected coating material, for example ejected ink, is small in comparison to a method in which all nozzles eject coating agents at regular intervals.
  • Another advantage is preferably that unnecessary disturbances in a printed printed image are avoided.
  • Preferably, raster data and / or output data and / or control data that belong to successive printed images and / or original image data are processed together and checked for corresponding consequences. As a result, even more coating agent can be saved and / or even better print quality can be achieved.
  • For example, a single page is 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 a magazine. A single page can also be a poster and printed as a single motif on a sheet of a finished printed product. For example, a single page can have multiple objects, but they are treated together when it comes to describing the overall print image. For example, a total print image may have two individual pages which correspond to two pages of a newspaper, while at least one of these individual pages has as objects at least one text block and at least one graphic. Preferably, at least with respect to displacements made within data, a single page is the smallest unit that remains unchanged in itself.
  • An advantage of the invention is preferably that passer and / or register of printed products can achieve a higher quality, in particular by compensating as preferred changes in dimensions of a printing material before applying a corresponding coating agent. Another advantage is preferably that individual print jobs can be addressed individually, whereby the quality of the printed products can be further increased than when flat-rate solutions are used. Another advantage is preferably in the simple applicability for operators of the printing press, in particular due to a 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 press are described, preferably from digitally stored template image data at least a first complete print image first output data for producing or driving at least one at least one form of printed images, in particular at least individual pixels of Print image defining component of at least a first printing unit of the printing machine to generate at least a first printed total print image and preferably wherein the particular digitally stored template image data of the at least one first complete print image at least template image data at least a first single page and preferably also template image data at least a second single page and preferably by a first printing operation by means of the at least one first printing unit according to the first Au output data that at least one first printed total print image is generated on the at least one printing material.
  • Preferably, the at least one first single page and the preferred at least one second single page within in particular digitally stored data while maintaining at least their respective measured in a first storage direction absolute virtual page dimension as a function of order related to a print order data and / or as a function of in at least one Correction memory stored correction data relative to each other at least shifted in this first storage direction. As a result, there is preferably the advantage that printed individual pages originating from different printing units lie in the finished printed product in register and / or in register with each other. Preferably, a degree of relative displacement depends on how far the individual pages have previously been spaced apart. Printed individual pages, which have a greater distance from one another, are moved more strongly relative to each other, for example, by changes in the dimensions of the printing material, which is preferably compensated by a greater relative displacement of the individual pages in the original image data.
  • As passers-fair it is preferred to also consider those individual pages whose centers lie on one another, regardless of whether their side dimensions differ. Such a difference is perceived by the viewer as less disturbing than completely shifted single pages. In this case, those individual pages whose center points are superimposed in the transmitted light of the printing material, irrespective of whether their side dimensions differ, are preferably also considered to be arranged in register. Such a difference is also perceived by the viewer as less disturbing than completely shifted single pages.
  • Preferably, the at least one first individual page in its template image data is assigned at least one virtual first page dimension in a first template direction and one virtual first reference point, and the at least one second single page in its template image data is at least one virtual second reference point and more preferably at least one virtual second page dimension assigned to this first Vorlagerichtung and and are measured in a first printed image direction reference distance, the first reference point and the second reference point to each other on the at least one first printed total image on the one hand and the first side dimension of a printed first single page on the other hand in a dimensional pressure ratio, the preferably as a function of order data related to a print job and / or as a function of correction data stored in at least one correction memory of one dimension s template ratio deviates in which a measured in the first Vorlagerichtung virtual reference distance associated with the virtual first reference point and the virtual reference point to each other in the template image data of the at least one first complete printed image, on the one hand and the virtual first page dimension of the at least one first single page in On the other hand, the template image data are related to each other. This can be the case, for example, in the case of a pure displacement of the individual pages. However, it is also possible to achieve this by a combination of shifting of individual pages and stretching of individual pages and / or overall printed images. Thus, for example, by shifting the individual pages whose centers bring to cover and additionally adjust their dimensions by individual extension of the individual pages.
  • As an alternative or in addition, at least the at least one first single page within particularly digitally stored data is preferred before and / or during the generation of the output data as a function of the order image data and depending on order data related to the print job and as a function of correction data stored in at least one correction memory stretched at least in the first Vorlagerichtung with a first aspect ratio. By stretching at least one single side and / or stretching, for example, a total print image, uniform changes of dimensions of the printing material can preferably be largely or even completely compensated for. Although this variant requires an intervention in the template image data of the corresponding individual pages themselves, but achieved as regards passer and / or register results of very high quality.
  • The preferred method is preferably suitable on the one hand for controlling nozzles of printheads of at least one first printing unit of the printing machine, in particular for controlling ejection of coating agent through nozzles of printheads, 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 pixels, for example digital thermal printing processes, printing methods based on electrical charging, for example using a toner as coating agent or the like. On the other hand, the method is preferably suitable for controlling at least one production device for producing fixed printing plates, for example for imaging printing plates in offset printing and / or for producing printing forms for high-pressure and / or flexographic printing and / or gravure printing. Then, the method is used to produce particular solid printing plates, such as printing plates.
  • The at least one printing unit is preferably an ink-jet printing unit and / or the first printing unit of the at least one first printing unit of the printing machine is generated from the particularly digitally stored original image data of the at least one first complete printed image where ejection of coating agent by these nozzles is performed by printheads to produce the at least one first printed total image and / or the respective output data are control data of respective nozzles to be used by printheads of at least one inkjet printing unit of the printing machine.
  • Particularly in connection with digital printing methods, for example inkjet printing methods, the advantage that the change of the data, for example the shifting of individual pages and / or stretching of single pages or complete printed images can be carried out relatively late, in particular only when it is already established with which Printing machine and / or on what substrate and / or under which climatic conditions and / or with which coating a print job to be executed. 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 quantity, then the method can be used directly before the start of printing and take these changes into account. It is also possible to react to changes in environmental conditions, for example altered air humidity. Such Changes can even be made in the course of a print job in digital printing processes, be it because of changed conditions, changed printing material on a flying reel change, or due to measurements on print products already produced within the same print job.
  • Preferably, the displacement of at least one individual page and / or the extension of at least one individual page and / or at least one overall printed image and / or at least one reference distance depends on the original image data at least insofar as the original image data has information about which individual pages of the overall printed image are arranged , A shift of a single page will preferably be the greater, the further this single page has already been arranged away from a reference point, for example a center line of the overall printed image, in particular because then the change of the at least one dimension of the printing material will have even greater effects. A shrinkage of a printing material web would move, for example, more strongly arranged on the edge of this printing material single pages, as such single pages, which are arranged close to the center line of the printing material. Therefore, to compensate for the arranged on the edge of individual pages have to be moved earlier stronger. This is the more relevant the more individual pages are arranged side by side and / or the smaller the individual pages are each. With a uniform stretching of the total print image, a regular change in the side dimension of the printing material can be compensated for.
  • Alternatively or additionally, a method for printing at least one printing substrate by means of at least one printing unit of a printing machine, wherein from at least a first complete print image first output data for producing or driving at least one at least one form of print images defining constituent of at least a first printing unit of the printing machine for Generating at least a first printed total printed image and wherein the stored template image data of the at least one first complete printed image at least template image data at least a first single page and template image data at least a second single page and wherein the at least one first single page and the at least one second single page within stored data while maintaining at least their respective measured in a first storage direction absolute virtual page dimension by a machine control and / or a print data processing of the printing press itself and / or by at least one stored algorithm of machine control and / or print data processing of the printing press relative to each other at least shifted in this first Vorlagerichtung and wherein a first printing operation by means of the at least one first printing unit according to the first output data the at least one first printed total print image is generated on the at least one printing substrate.
  • An advantage of a preferred, additional or alternative method for coating a printing substrate by means of printing units of a printing machine, wherein the printing material is coated along a transport path by means of at least a first printing unit and preferably at least a second printing unit and wherein at least six different coating agent on a same first side of the Substrate are applied and wherein each of these at least six different coating agent in each case by means of a plurality of individually controllable and depending on output data and in particular control data individual pixels of print images defining constituents of at least a first printing unit and / or at least a second printing unit of the printing press is applied to the substrate and wherein by means of the at least one first printing unit at least three different coating agents on the first side of the printing substrate be applied and applied by means of the at least one second printing unit at least three different coating agent on the first side of the substrate, in particular, that also by means of controllable, in particular digitally controllable, individual pixels of print images defining constituents of at least one printing unit high-quality printed products can be generated which differ, for example, by their variety of colors and / or by finishes and / or further from simpler printed products. In this way, for example, in packaging printing high-quality yet individual print images can be generated. This applies in particular in connection with inkjet printing units, since they can apply a multiplicity of different coating agents in variable printed images in a particularly simple manner. In particular, then, the individually controllable and depending on output data and in particular control data individual pixels of print images constituent components nozzles of ink jet printheads 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 press, wherein at least one first printing unit and at least along a transport path provided for at least one printing substrate to be printed by the printing press a second printing unit is arranged, and wherein the printing machine has at least five, more preferably at least six, even more preferably at least seven, and even more preferably at least eight different buffers for different coating agents and wherein each of these at least five, more preferably at least six, even more preferably at least seven and even more preferably at least eight latches each having 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 connected and / or connectable and preferably by means of each of these components depending on output data and in particular control data individual printed pixels of printed printed images can be generated and wherein preferably each of these components on a same side of the provided for the at least one printing substrate Tran Sportweg is arranged by the printing press and wherein preferably the at least one first printing unit at least one, more preferably at least two, even more preferably at least three and even more preferably at least four of the different buffer for different coating agent and preferably wherein the at least one second printing unit at least one , more preferably at least two, even more preferably at least three and even more preferably at least four of the different temporary storage for different coating agent.
  • An advantage of a preferred method, in which preferably additionally from stored template image data of at least one first complete print image, first output data and / or control data for driving the at least one individual pixel of print images defining component of the at least one first and / or second printing unit for generating at least a first printed The stored template image data of the at least one first complete print image preferably at least template image data at least a first single page and preferably also template image data at least a second single page and the at least one first single page and the at least one second single page preferably within stored data preferably while retaining at least their respective measured in a first storage direction absolute virtual page dimension depending on order related to a job order data u and / or at least the at least one first individual page within stored data as a function of the original image data and as a function of order data related to a print job, and / or in at least one first single page within stored data relative to each other Dependent on stored in at least one correction memory correction data before and / or stretched during the generation of the output data, at least in the first Vorlagerichtung with a first stretch factor, is in particular that it can be printed passerhaltig and / or register, even if different printing units used come and / or change dimensions of the printing material between the printing units, for example due to the action of a dryer.
  • This advantage is given in particular if, as preferred, by the extension of the at least one first individual side and / or the extension of the at least one second individual side and / or the extension of the at least one virtual reference distance and / or by the relative displacement of the at least one first individual side and at least one change of at least one dimension of the printing material is at least partially compensated for in the template image data of the at least one second individual page.

In particular, it can then preferably be prevented that undried coating agent contaminates the printed product and / or the printing press, and preferably a clean and register-containing and / or registration-containing printed image is 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 provided by the printing press for at least one printing substrate to be printed.
  • A further advantage arises in particular if, as 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 compositions comprises 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 a coating agent of the color gold and / or silver and / or iron oxide particles and / or has a positive or negative magnetic susceptibility and / or ferromagnetic or ferrimagnetic or antiferromagnetic properties and / or is a water-based coating agent and / or has at least one organic solvent and / or is crosslinkable by means of UV light and / or electroconductive and / or is visible only under UV light, because this is preferably a variety of different and / or sophisticated and / or tamper-proof and / or functional print images can be realized.

  • An advantage of this preferred method is, in particular, that a relatively small memory for the secondary data packets can be used and / or that particularly large print images and in principle also in at least one direction endlessly extending printed print images can be created, which originate from a digital print image template , Without the division of the data, a limitation would be given, for example, by a memory which stores, for example, raster data, which are then retrieved from this memory and converted into output data. By splitting data packets that are too large for this memory, it is preferable to produce very long printed print images in high quality. Through the preferred use of a buffer and / or ring buffer and / or shift register, seamless printing is made possible even at high printing speeds, because less large data memories have to be emptied and refilled. In particular, thereby emptying and / or filling of the corresponding data memory can be decoupled from a reading of this data memory. If, as preferred, the division of a primary data packet into a plurality of secondary data packets is carried out only if a limit value is exceeded and / or by a machine control and / or print data processing and / or an algorithm stored therein, it is possible to work in a particularly flexible manner, for example because a printer has differently configured ones Printing presses do not have to determine in advance which press is used and in what kind consequently the data packets should be divided. In particular, if each printing press has, for example, its own configuration-dependent at least one limit value, unnecessary expenditure in the 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 be created from it, which can then be converted into raster data or geometrically modified raster data. As a result, the raster process can preferably be carried out with relatively small data packets in each case. This facilitates data handling during screening and allows printing of very large print images.

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 would not be sufficient to the raster data 647 save if the entire primary data packet should be stored 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 Packaged into the appropriate memory and deleted from it again.
