ABSTRACT:
A method for making a lithographic printing plate from an original containing multiple tones comprising the steps of frequency modulation screening the multiple image to obtain screened data representing tones of the multiple tone image in terms of halftone dots; reproducing the halftone dots on a lithographic printing plate precursor having a surface capable of being differentiated in ink accepting and ink repellant areas upon scanwise exposure and an optional development step, by means of a scanwise exposure, wherein the scanwise exposure for rendering a halftone dot is intensity modulated.
