摘要 |
A method of making a lithographic printing plate comprising the steps of : a) providing a lithographic printing plate precursor comprising (i) a support having a hydrophilic surface or which is provided with a hydrophilic layer, (ii) a coating on said support, comprising a photopolymerizable layer, and, optionally, an intermediate layer between the photopolymerizable layer and the support, wherein said photopolymerizable layer comprises a polymerizable compound, a polymerization initiator and a reactive binder, b) image-wise exposing said coating 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 photopolymerizable layer from the support , whereby said reactive binder is a polymer containing a monomeric unit which comprises a group having an ethylenically unsaturated bond. |
