Abstract

Die Erfindung beschreibt ein Verfahren zur Herstellung einer Tiefdruckform, welche für die Ausbildung von Rasternäpfchen mittels Laserstrahlen geeignet ist und welche wenigstens aus einem Grundkörper und einer metallischen Aussenschicht besteht. Dabei wird die die metallische Aussenschicht durch ein pulver-basiertes Spritzverfahren auf den Grundkörper aufgebracht, wobei sich ein Kaltgasspritzverfahren als besonders geeignet erwiesen hat. Des Weiteren betrifft die Erfindung Tiefdruckformen, welche eine metallische Aussenschicht aus einer Legierung von Zink mit wenigstens einem weiteren Metall, insbesondere aus der Reihe Nickel, Kupfer, Zinn und/oder Titan, besteht oder eine derartige Legierung enthalten.

The invention describes a method for the production of a gravure printing form, which is suitable for the formation of screen cavities by means of laser beams and which consists of at least one base body and one metallic outer layer. In this case, the metallic outer layer is applied to the base body by a powder-based spraying method, whereby a cold gas spraying process has proven to be particularly suitable. The invention further relates to intaglio printing forms, which comprise a metallic outer layer of an alloy of zinc with at least one further metal, in particular from the series nickel, copper, tin and / or titanium, or contain such an alloy.
