Description

Verfahren zum Herstellen von Flachdruckformen Im Hauptpatent ist ein Verfahren zur Herstellung von Flachdruckformen beschrieben, nach welchem die Unterlagen für die Druckformen vor oder nach dem Aufbringen des Druckbildes mit einem Metallüberzug versehen werden, und zwar ist die Metallzerstäubung beispielsweise durch Aufspritzen vorgeschlagen worden.Method for producing planographic printing forms In the main patent is a Process for the production of planographic printing forms described, according to which the documents for the printing forms before or after the application of the printed image with a metal coating be provided, namely the metal atomization is for example by spraying has been proposed.

Es ist nun bekannt, daß man eine viel feinere Metallzerstäubung auf dem Wege der Kathodenzerstäubung im Vakuum erzielen kann. Gegenstand der Erfindung ist die Anwendung dieser Kathodenzerstäubung bei der Durchführung des Verfahrens nach dem Hauptpatent. Auf dem Wege der Kathodenzerstäubung im hohen Vakuum erreicht man einmal eine viel feinere Zerstäubung des Metalls, dann aber den Vorteil, daß die zerstäubten Metallteilchen auch in die Tiefen der Form intensiv eindringen und die gewonnenen Metallüberzüge an den jeweiligen Unterlagen außerordentlich fest haften. Da es heute nach den bekannten Kathodenzerstäübungsverfahren keine Schwierigkeit bietet, auch wärmeempfindliche Unterlagen auf diesem Wege zu behandeln, ist es möglich, auch elastische Unterlagen, beispielsweise glatte oder körnige Gummitücher, Gummiwalzen usw., in für den Flachdruck brauchbare Druckformenträger überzuführen.It is now known that one can obtain a much finer metal atomization can achieve the path of cathode sputtering in a vacuum. Subject of the invention is the use of this cathodic sputtering when performing the process according to the main patent. Achieved by way of cathode sputtering in a high vacuum you get a much finer atomization of the metal, but then you have the advantage that the atomized metal particles also penetrate deeply into the mold and the metal coatings obtained on the respective documents are extremely strong be liable. Since today there is no difficulty in using the known cathode atomization process offers to treat heat-sensitive documents in this way, it is possible also elastic substrates, for example smooth or granular rubber blankets, rubber rollers etc., to be transferred into printing form carriers that can be used for planographic printing.
