Abstract

Method and device for producing a printing block In a printing block a relief is introduced into the surface of a printing block blank (1) in that material of the printing block blank (1) is removed in regions along tracks by radiation in order by this means to form recesses (V) between which plateaus come to lie. According to the invention the surface of the printing block blank (1) located between the recesses (V) is also removed by radiation in order by this means to obtain lower-lying plateaus (P2).

Description

technical field

[0001] The invention relates to a method and a device for producing a printing block as claimed in claims 1 and 21 . The printing block may be, for example, a flexible or offset printing block capable of functioning as a relief printing or gravure printing block. Background technique

[0002] In order to resort to a conventional CO 2 The laser generates an offset printing block, which is generally known to burn the material in sequence directly from a printing plate, which may for example be a polymer printing plate, in this way creating a relief in the printing plate. During this process, CO 2 The laser is permanently and sequentially modulated in power in this way to obtain a notch surrounding the relief on the surface of the printing plate.

[0003] Furthermore, in order to generate an offset printing block, PCT / EP96 / 05277 has disclosed the sequential use of two laser beam sources, with the first laser beam source obtaining a fine structure in a desired...
