Definitions

  • the invention relates to a method for producing multicolor printing by means of digital illustrated printing plates.
  • DE-A-195 08 842 describes a method for producing a multicolor print by means of digitally illustrated / described printing plates.
  • everyone will Transfer the color separation of a print image to one transfer film each, the transfer films on the sheet path to the respective printing units and further to the delivery and each color separation of the print image via a medium from the transfer film to the respective one Transfer printing plate.
  • DE-A-26 39 993 describes an offset printing machine with the inking unit assemblies, Dampening unit and printing unit. The surface of the impression cylinder after the impression has been taken is neutralized and the printing plate is reprocessed in the machine.
  • the object of the invention is to provide a method which is an economical solution for multi-color printing, especially in large format.
  • the inventive solution is explained in more detail using an exemplary embodiment.
  • the printed printing plates are removed from the printing form cylinders on which they are clamped. This is expediently carried out with plate changing machines with which the printed printing plates are removed from the printing form cylinders and new printing plates are fed to the printing form cylinders.
  • the printed printing plates are now fed to a device for neutralization and neutralized. Neutralization is understood to mean that the printed image is removed from the printing plates. This is done by chemical, mechanical or thermal means, preferably using laser technology. With neutralization, almost the same surface tension is achieved. The neutralized printing plate is then imaged / written again.
  • This imaging / writing is done digitally from digital data sets (CtP).
  • the printing plate In order to ensure that the printing plates fit on the printing form cylinder, the printing plate must be fixed in the exposure unit with the printing plate's own pass system or with a second pass system that is related to the printing plate pass system, whereby the pass system must be dimensionally stable.
  • the printing plates are fed back to the printing form cylinder, preferably by means of an automatic plate changing device.
  • the printing plate used for this process is preferably made of stainless steel, dimensionally stable and plate-free, which can have further surface finishes known for offset (eg chrome layer).
