Abstract: A method according for preparing a lithographic printing plate containing a lithographic image consisting of printing areas and non-printing areas includes the steps of jetting and curing droplets of a first curable fluid on a hydrophilic support thereby forming a printing area of the lithographic image; and jetting and curing droplets of a second curable fluid in a non-printing area of the lithographic image thereby forming a hydrophilic protective layer on the hydrophilic support.

Abstract: A method of preparing a lithographic printing plate includes the steps printing a liquid on a lithographic support to form a printing area which corresponds to a raster image, wherein the raster image includes a section which has a tone-value from 90% to 100%, and the jetted liquid droplets for this section, on a corresponding part from the printing area on the lithographic support, are contactless with each other.
