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).

Method for producing a printing block in which 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, characterized in that the surface of the printing block blank (1) located between the recesses (V) also is removed by radiation in order by this means to obtain lower-lying plateaus (P2).
Device for producing a printing block having:
- a mounting for holding a printing block blank (1);
- an optical device (27) for exposure to radiation of a surface (2) of the printing block blank (1) along a track by means of at least one beam (28) in order by this means to remove regions of the printing block blank (1) to form recesses (V);
- and
- a control device which by use of a data file containing beam-on and beam-off control commands controls changes in the intensity of the at least single beam on its path along the track, characterized in that the control device is constructed in such a way that it provides at least one data file (D1, D2) each containing beam-on and beam-off commands in order also to remove by radiation the surface of the printing block blank (1) located between the recesses (V) in order by this means to obtain lower-lying plateaus (P2).
