Abstract

Verfahren zum Behandeln von erneut bebilderbaren Druckformen oder Druckformzylindern in Druckmaschinen, wobei die Oberfläche der Druckform (12)/des Druckformzylinders (4) hydrophil ist, auf diese durch einen Strahldrucker (8) eine hydrophobe, bebilderbare Schicht aufgebracht wird und anschließend das Bebildern mittels einer Bebilderungseinrichtung (9) erfolgt.Process for treating reimageable printing forms or printing form cylinders in printing presses, the surface of the printing form (12) / the printing form cylinder (4) is hydrophilic, on this by a jet printer (8) a hydrophobic, imageable Layer is applied and then the imaging by means of an imaging device (9) is done.

Die Aufgabe der Erfindung besteht darin, ein Verfahren zum Behandeln von erneut bebilderbaren Druckformen oder Druckformzylindern in Druckmaschinen zu entwickeln, durch das unter Einhaltung hoher Qualitätskriterien ein Minimum an Beschichtungsmaterial verbraucht wird und nahezu keine Verbrennungsrückstände erzeugt werden.The object of the invention is a method for treating reimageable To develop printing forms or printing form cylinders in printing machines, due to a minimum of coating material while maintaining high quality criteria is consumed and almost no combustion residues are generated.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Bereiche der Oberfläche der Druckform (12)/des Druckformzylinders (4), denen Motive (13, 14) zugeordnet sind, ermittelt werden und die bebilderbare Schicht so aufgetragen wird, dass nur diese Bereiche einschließlich eines über die Motive (13, 14) hinausgehenden minimalen Randbereichs (16) beschichtet werden.

Figure 00000001
According to the invention, the object is achieved in that the areas of the surface of the printing form (12) / the printing form cylinder (4) to which motifs (13, 14) are assigned are determined and the imageable layer is applied in such a way that only these areas, including one minimal edge area (16) beyond the motifs (13, 14) are coated.
