Abstract

A process for the production of flexographic printing plates by laser engraving, in which the recording layer of a crosslinkable, laser-engravable flexographic printing element is crosslinked by the combination of a full-area crosslinking step with a crosslinking step which only acts at the surface, and a printing relief is engraved into the crosslinked recording layer by means of a laser, and flexographic printing plates obtainable by the process.
