Abstract (en)

According to the present invention there is provided a method for making on-press lithographic printing plates which require no processing. The method comprises the steps of: a. mounting a heat-sensitive imaging material, comprising on a lithographic base having a hydrophilic surface, a metallic layer or a metal oxide layer and on top thereof an oleophobic layer having a thickness of less than 5 mu m, on a print cylinder of a printing press; b. image-wise exposing said imaging material with an IR-laser; c. rotating said print cylinder while supplying an aqueous dampening liquid and/or ink to said image forming layer of said imaging material
