Aus der Druckschrift DE 195 08 843 A1 ist ein Verfahren zur Bebilderung bzw. zur Bebilderung und Neutralisation einer Druckplatte eines Druckformzylinders in einer ein Farbwerk, druckbildübertragende und bogenführende Zylinder enthaltenden Druckmaschine, insbesondere Mehrfarbendruckmaschine, einschließlich Anleger und Auslage, wobei die einzelnen auf die Druckplatte aufzubringenden Druckbildinformationen in digitaler Form vorliegen, bekannt. Zur Verwendung der Druckplatte in der Druckmaschine wird ein die Druckbildinformationen tragendes Medium auf die Druckplatte aufgebracht und das aufgebrachte Medium nach dem Druckprozess abgelöst.
Die Einrichtung zur Druckplattenbebilderung enthält gegebenenfalls eine integrierte Aushärteeinrichtung und eine Ablöseeinrichtung. Die Aushärtung des auf die Druckplatte aufgebrachten Mediums erfolgt mittels UV-Härtung oder Strahlenhärtung.
Über die Funktion der Abläseeinrichtung werden keine näheren Ausführungen gemacht.Document DE 195 08 843 A1 describes a method for imaging or for imaging and neutralizing a printing plate of a printing form cylinder in a printing machine containing an inking unit, image transfer and sheet guiding cylinders, in particular a multicolour printing machine, including feeder and delivery, the individual being applied to the printing plate Print image information is available in digital form. To use the printing plate in the printing press, a medium carrying the print image information is applied to the printing plate and the applied medium is detached after the printing process.
The device for printing plate imaging optionally contains an integrated curing device and a detaching device. The medium applied to the printing plate is cured by means of UV curing or radiation curing.
No further details are given on the function of the discharge device.

Aus der Druckschrift DE 41 23 959 C1 ist ein Verfahren zur Regenerierung einer vorzugsweise vorher direkt bebilderten für den Offsetdruck geeigneten Druckform bekannt. Die Regenerierung der Druckplatte umfasst die Entfernung der Bebilderung auf der Druckform und eine Hydrophilierung der Oberfläche der Druckform.
Gemäß dieser Druckschrift erfolgt die Regenerierung dadurch, dass auf die Druckform ein ionisiertes Prozessgas mittels einer Beaufschlagungseinrichtung aufgebracht, wobei ein reaktives Löschen der Bebilderung und die gleichzeitige Hydrophilierung in einem Prozessschritt vorgenommen wird. Die dabei entstehenden flüchtigen Reaktionsprodukte werden mittels einer Absaugvorrichtung abgeführt.
Nachteilig an dieser Regenerierungseinrichtung ist der hohe technische Aufwand, der für die Regenerierung der Druckplatten betrieben werden muss.From the document DE 41 23 959 C1, a method for the regeneration of a printing form which is preferably previously directly illustrated and is suitable for offset printing is known. The regeneration of the printing plate comprises removing the imaging on the printing form and hydrophilizing the surface of the printing form.
According to this document, the regeneration takes place in that an ionized process gas is applied to the printing form by means of an application device, a reactive deletion of the images and the simultaneous hydrophilization being carried out in one process step. The resulting volatile reaction products are removed by means of a suction device.
A disadvantage of this regeneration device is the high technical outlay which has to be carried out for the regeneration of the printing plates.
