Abstract

Die Erfindung betrifft ein Verfahren zur Behandlung von Druckplatten in Druckmaschinen für den Offsetdruck, wobei die Druckplatten direkt in der Druckmaschine beschrieben, verdruckt und danach wieder regeneriert werden.The invention relates to a method for treating printing plates in printing machines for offset printing, the printing plates being written directly in the printing press and then regenerated again.

Aufgabe der Erfindung ist es, ein Verfahren zu schaffen, das für in der Druckmaschine bebilderte Druckplatten eine hohe Standfestigkeit sowie deren schnelle und ohne großen Aufwand zu bewerkstelligende Wiederverwendung zur erneuten Bebilderung ermöglicht.The object of the invention is to provide a method for imaging in the printing press Printing plates have a high stability as well as their quick and without great effort reuse for re-imaging enabled.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass ein die Druckbildinformationen tragendes Medium auf die Druckplatte aufgebracht und das Medium ausgehärtet wird, dadurch gekennzeichnet, dass die Aushärtung des Mediums mittels Laser erfolgt oder dass das Medium erhitzt auf die Druckplatte (9) aufgebracht und die Aushärtung durch Kühlung erreicht wird und dass das Medium mittels Laser von der Druckplatte (9) entfernt wird.

Figure 00000001
According to the invention, the object is achieved in that a medium carrying the print image information is applied to the printing plate and the medium is cured, characterized in that the medium is cured by means of a laser or that the medium is applied to the printing plate (9) when heated and the curing is carried out by Cooling is achieved and that the medium is removed from the printing plate (9) by means of a laser.
