Definitions
- the invention relates to a method for setting the register in a multi-color printing press with several devices for the digital generation of partial color images, whereby when feeding printing substrates of a different kind to Correction of the register setting, the creation and merging of the part color images is controlled.
- the invention further relates to a device for carrying out the method a multi-color printing machine with several devices for digital generation of partial color images, with at least one controller when feeding printing substrates another type a register correction by controlling the generation and Merges the part color images.
- a method and a device of the type mentioned at the outset is known from US Pat. No. 5,689. 757 known. It teaches there when feeding substrates of a different kind to take into account the influence of paper roughness on the register. For this, the Roughness of a paper to be printed is recorded. The influence of paper roughness on the register is then considered by the register control before the paper is fed to the printing process.
- the invention is therefore based on the object of a method and a device of the type mentioned in such a way that in the event of a change in the printing substrate counteracted the influence of this change on the register to a high degree before the printing substrate is fed to the printing process.
- the object is achieved according to the invention in that a change in print substrate thickness due to a change of print substrate the printing substrate thickness on the register using existing influencing variables directly is taken into account when implementing the change.
- the at least one controller is designed such that it changes when the Print substrate thickness due to a change of print substrate the influence of the print substrate thickness on the register using the available influencing variables directly with the Implementation of the change considered.
- the invention is based on the knowledge that when changing the printing substrate the decisive influencing variable with regard to the register is the printing substrate thickness. This stems from the fact that the movements of the drawing and substrate-carrying elements Friction are linked. This is done by changing the print substrate thickness the for the transmission ratio between the print substrate carrier and decisive radius changed in a cylinder. This changing gear ratio affects the register to a much greater extent than the paper roughness. Above all, there is no other regarding the influence of the printing substrate thickness Possibility as the consideration when creating and combining the part color images. The influence of paper roughness, however, can be done in other ways can be counteracted, in particular by slipping through less Power transmission, the surface condition of the drawing frame cylinders as well the quality of the toner or other factors influencing the power transmission Materials is counteracted.
- the influence of the Register is essentially detected by a change of printing substrate.
- the printing process is taken into account when setting the register, it is possible that the occurrence of a register error is prevented from the outset, so that test prints on printing substrates, for example with register marks, is generally not required are.
- This is economical, especially for short runs or single copies important because machine time and often also printing substrates are saved.
- test prints are on the print substrate carrier without feeding Printing substrates for the correction of other influences on the register possible because the essential influence of the printing substrates is taken into account by the detection of their thickness is.
- the measure according to the invention enables a register setting of a known type to be optimized in such a way that they change with print substrate changes when printing page changes not "getting out of hand" first to be corrected afterwards, but the register setting remains within the range of tolerable fluctuations, so that continue printing with another type of printing substrate without interruption can be.
- the invention includes the additional consideration of others Influencing factors, such as the paper stiffness, the toner application and also the paper roughness, not as far as they have an influence on the register. It plays with the invention Measure also does not matter whether the print substrate carrier with the Print substrates for transferring the partial color images directly with the image cylinders cooperates or whether image transfer cylinders are interposed.
- a further development of the method provides that as a result of a register correction a change in the print substrate thickness, the retroactive influence of the print substrate thickness the previous but still in the printing process on the print page Register of the new print page already in the printing process is taken into account. It is taken into account for each printing unit if the gear ratio is still is determined by the printing substrates of the previous printing page, while already an illustration of the image cylinder with a partial color image of the new print page is made. It is also taken into account how this change of Printing substrate thicknesses takes place successively on one printing unit after the other, so to speak, "runs through the machine". In this way the register is correct the prints are even better guaranteed when changing the print page.
- the printing press can continue printing without interruption even if between the creation of two partial color images the print page change takes place in such a way that the new partial color image is already being created, while the previous partial color image is the previous print page not yet or not yet completely transferred to the print substrate has been.
- the register accuracy is therefore also high in this Guaranteed overlap between two printed pages and any mutual Influencing is compensated. This will make the printing press more economical significantly increased.
- the at least one controller is designed such that it is in a register correction due to a change in the substrate thickness the retroactive influence of Print substrate thickness of the previous one, but still in the printing process Print page on the register of the new print page already in the printing process considered.
- the influencing variables of the printing substrate thicknesses can be taken into account on the basis of stored Data done.
- the detection of a print substrate thickness change by the Changing the type of printing substrates can be due to manual entry or by measuring the thicknesses of the printing substrates before they are fed to the printing process respectively.
- the influencing variables can be entered yourself or it is possible that data stored by the entry is activated for the register setting become. It is also possible that the consideration of the printing substrate thicknesses due to a saved file of the print pages.
- the influencing factors can be stored as stored data, the different print substrate thicknesses or are assigned to different types of paper.
- the device can be provided with at least one memory is equipped, the stored empirical values of influencing variables of different Includes print substrate thicknesses, with the at least one control based of these empirical values, the creation and the assembly of the partial color images controls.
- the device is equipped with at least one memory, the stored Contains empirical values of influencing variables of different print substrate thicknesses, whereby the at least one controller using this data to create and merge controls the part color images.
- the device can be a device for measuring printing substrate thicknesses have and the consideration of the latter activated by the device become. It can also have a press control and memory with files from Print pages may be provided, taking into account the influencing factors of various Print substrate thicknesses are based on these files. In this case it is useful if the files of the printed pages with different data stored Print substrate types are linked.
- the invention has the purpose of correcting an intended one To serve register regulation.
- the latter can be designed such that it is on the detection is based on register marks, which are printed by the individual printing units become.
- the invention provides that this correction is carried out before a printed page and print substrate changes can affect the register marks.
- the at least one controller in this way is designed so that the register by means of register marks, which the individual Printing units printed and a register sensor are recorded, controls and the influencing variables the printing substrate thicknesses are taken into account as correction factors, the Correction is made before a print substrate and print page change affects the Can have registers.
- the invention can also be used to correct a register regulation based on the detection of the positions of the part-color image and substrate-carrying elements.
- the at least one controller is designed so that it registers by detecting the positions of the Part color image and substrate-carrying elements through position detection elements regulates and takes into account the influencing variables of the print substrate thicknesses as correction factors.
- the position detection elements can, for example, be rotary angle transmitters act. Such corrections are made before changes affect the Can have register marks.
- influencing variables that influence the Registers resulting from a change have been taken into account when setting the register become.
- it can be toner profiles, types of paper, paper stiffness or other influencing factors.
- at least one controller may be provided which takes these into account Influencing factors is formed.
