    • 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, a sensitizer and a binder, b) image-wise exposing said coating in a plate setter whereby said precursor is exposed with light having a wavelength ranging between 350 and 450 nm, 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 , wherein said sensitizer is a compound which absorbs light having a wavelength ranging between 350 and 450 nm, and comprises a solubilizing group capable of solubilizing the sensitizer in the gum solution
    • 一种制备平版印刷版的方法,包括以下步骤:a)提供平版印刷版前体,其包含(i)具有亲水表面的或具有亲水层的载体,(ii)所述载体上的涂层, 可光聚合层和可选择地在可光聚合层和载体之间的中间层,其中所述可光聚合层包含可聚合化合物,聚合引发剂,敏化剂和粘合剂,b)在印版机中成像曝光所述涂层 其中所述前体用波长范围在350和450nm之间的光一起曝光,c)任选地,在预热单元中加热前体,d)通过用前述的前体处理来涂覆前体, 从而从载体除去可光聚合层的未曝光区域,其中所述敏化剂是吸收光的化合物h 具有在350和450nm之间的波长,并且包括能够使敏化剂溶解在胶溶液中的增溶基团
