Patent ID: 8232043

Claim:
A method of making a lithographic printing plate comprising the steps of: a) providing a lithographic printing plate precursor including a support having a hydrophilic surface or which is provided with a hydrophilic layer, a coating on the support including a photopolymerizable layer including a polymerizable monomer or oligomer including an ethylenically unsaturated compound having at least one terminal ethylenic group and a free radical polymerization initiator, and, optionally, an intermediate layer between the photopolymerizable layer and the support; b) image-wise exposing the coating by a laser in a plate setter; c) optionally, heating the precursor in a preheating unit; d) developing the precursor off-press in a gumming unit by treating the coating of the precursor with a gum solution, thereby removing the non-exposed areas of the coating from the support; wherein the coating further includes a compound capable of interacting with the support, the compound being present in the photopolymerizable layer.
