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 by radiation. The relief regions may be formed at different depths along one and the same track by frequent exposure to radiation.
Claims32
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 along tracks by radiation;
- and
- producing along one track, relief regions located at different depths by frequent exposure to radiation,
- wherein the exposure to radiation ensues with multiple beams, which are selectively controlled and guided along the same track.
1 more element
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;
- 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 a plurality of data files, each containing beam-on and beam-off commands, and each serving for a timed, machining of the printing block blank along the entire track,
- wherein the optical device is constructed in such a way that it has the ability to emit a plurality of beams which are each controllable by one separate data file.
