Abstract
A method and apparatus for producing rastered printing forms, in which an image pattern is opto-electronically scanned to obtain an image signal, and the printing form production is effected by means of an energy beam recording device controlled by the image signal, whereby the raster points are recorded in a raster network having arbitrary raster angles, by means of relative motion between the printing form and the recording device, in which the pattern to be reproduced is scanned to simultaneously provide image signals for a plurality of adjacent image points of such a pattern, following which, for the control of the recording device, the image signal of that image point is selected whose local position on the image pattern is congruent with the local position of the raster point to be presently recorded, in the formation of the desired raster angles.
