Method for making a lithographic printing plate

Abstract

There is provided a method for making a lithographic printing plate from an original containing continuous tones comprising the steps of: screening said original to obtain screened data scan-wise exposing a lithographic printing plate precursor according to said screened data, said lithographic printing plate precursor having a surface capable of being differentiated in ink accepting and ink repellant areas upon said scan-wise exposure and an optional development step and optionally developing a thus obtained scan-wise exposed lithographic printing plate precursor, characterized in that said screening is a frequency modulation screening. The print results of a thus obtained printing plate can be previewed using simple proofing techniques.
