    • A method for preparing a lithographic printing plate comprises imagewise exporting a PS plate comprising an aluminum substrate having an anodized layer and a light-sensitive layer applied on one side of the substrate and then developing the PS plate with a developer comprising an aqueous solution of an alkali metal silicate, while compensating changes in the developer due to the development of the PS plate by supplementing, to the developer, a replenisher comprising an aqueous solution of an alkali metal silicate, wherein the PS plate is provided with a coating layer containing an organic polymeric compound on the back face and the replenisher is an aqueous solution of an alkali metal silicate having a ratio: [SiO.sub.2 ]/[M.sub.2 O] (wherein [SiO.sub.2 ] means molar concentration (mol/l) of SiO.sub.2 and [M.sub.2 O] is molar concentration (mol/l) of oxide M.sub.2 O of an alkali metal (M)) ranging from 0.3 to 1.0 and an SiO.sub.2 content ranging from 0.5 to 4.0% by weight. The method makes it possible to substantially reduce the amount of the developer to be replenished, does not cause any formation of insolubles even if a great deal of PS plates are processed over a long time period and thus stable developing treatment can be carried out.
    • 制备平版印刷版的方法包括成像输出PS板,其包括具有阳极氧化层的铝基板和施加在基板的一侧上的感光层,然后用包含水溶液的显影剂显影PS板 碱金属硅酸盐,同时通过向显影剂补充包含碱金属硅酸盐的水溶液的补充剂,由于PS板的发展而补偿显影剂的变化,其中PS板设置有包含有机物的涂层 背面上的高分子化合物和补充剂是具有[SiO 2] / [M 2 O]比率的碱金属硅酸盐的水溶液(其中[SiO 2]表示SiO 2和[M 2 O]的摩尔浓度(mol / l)为摩尔浓度 碱金属(M)的氧化物M 2 O浓度(mol / l)为0.3〜1.0,SiO 2含量为0.5〜4.0重量%。 该方法可以显着地减少补充的显影剂的量,即使长时间处理大量的PS板也不会形成不溶物,因此可以进行稳定的显影处理。
