Method for making a lithographic printing plate according to the silver salt diffusion transfer process |
摘要 |
The present invention provides a method for making a lithographic printing plate according to the silver salt diffusion transfer process comprising the steps of image-wise exposing an imaging element comprising on a support a photosensitive layer comprising silver halide emulsion(s) wherein less than 1 mole % of the silver halide is silver bromide and an image receiving layer containing physical development nuclei and developing said imaging element using an alkaline processing liquid with a pH lower than 11.5 in the presence of developing agent(s) and a meso-ionic compound.
