摘要:
An alkaline developing composition for processing a lithographic printing plate includes an alkali metal silicate and at least 6 weight % of a thickener such as glycerine. The lithographic printing plate can be either positive- or negative-working, and includes negative-working thermal plates.
摘要:
An alkaline developing composition for processing a lithographic printing plate includes an alkali metal silicate present in an amount to provide at least about 42 g SiO.sub.2 per 1000 g of composition, and a weight ratio of SiO.sub.2 to M.sub.2 O of from about 0.55 to about 0.925 wherein M is said the metal. The lithographic printing plate can be either positive- or negative-working, and includes negative-working thermal plates.
