Abstract
The invention is applicable in the sphere of the preparation of printing blocks or forms by means of electronic color scanners. The recording of line elements (lettering, signals, edge spike, etc.) by such scanners is concomitantly performed by selective energization of separate recording beams with greater line resolution than half-tone recording. Without losing time during recording, a stair-shaped distortion of smooth line contours is reduced in such degree that it no longer makes itself felt in troublesome manner in practice.
