Abstract
To produce a printing block, a relief is introduced into a surface of a printing block blank. To form the relief, material of the printing block blank is removed along tracks. The material is removed by radiation to form recesses, between which plateaus will be formed. The surface of the printing block blank located between the recesses is also removed by radiation in order to obtain lower-lying plateaus.
Claims36
A method for producing a printing block in which a relief is introduced into a surface of a printing block blank comprising the steps of:
- removing material of the printing block blank in regions along tracks by radiation;
- and
- forming recesses, between which plateaus result, wherein the surface of the printing block blank located between the recesses also is removed by radiation to obtain lower-lying plateaus.
A device for producing a printing block comprising:
- a mount for holding a printing block blank;
- an optical device for exposing radiation on a surface of the printing block blank along a track, said optical device including at least one beam to remove regions of the printing block blank to form recesses;
- and
- a control device which uses a data file containing beam-on and beam-off control commands which control changes in the intensity of the at least one beam on its path along the track, wherein the control device is constructed in such a way that it provides at least one data file containing beam-on and beam-off commands to remove by radiation the surface of the printing block blank located between the recesses to obtain lower-lying plateaus.
