ABSTRACT:
A method for generating a screened reproduction of a contone image comprises the steps of screening the contone image to obtain screened data representative for tones of the contone image and suitable for driving exposure of microdots on a radiation sensitive imaging element; exposing the microdots according to the screened data by at least one set or plurality (p) of radiation beams (b), characterized in that at a point in time (t) at least two radiation beams of the set of radiation beams impinge on a particular microdot (m) of a scanline (l). In particular is described a method for making a lithographic printing plate comprising the abovementioned steps.
