Abstract

See full text

The invention relates to a method for producing a relief printing plate, wherein a carrier having a polymer substrate layer is provided and a relief is formed on the surface of the substrate layer by layer, wherein the relief is formed by the following steps: applying a liquid comprising at least one reactive monomer onto the surface of the substrate layer, a single or multiple application of the liquid onto the surface of the polymer substrate layer, allowing the reactive monomer to diffuse into the polymer substrate layer for a specified exposure time, and allowing the relief to harden, wherein in step a) the liquid is applied onto the surface in the form of an image, and wherein after the specified exposure time according to step b) the liquid remaining on the surface without diffusing into the material is optionally removed from the surface, and in step c) the relief hardening of the polymer comprising the substrate layer and the reactive monomer diffused into the material is carried out.
