Abstract

A non-emulsion type plate finisher which comprises a solvent whose solubility in water at 20°C is not more than 5 % by weight. The plate finisher is excellent in the desensitizing ability and does not deteriorate the ink receptivity of image areas. The lithographic printing plate to which the plate finisher is applied has good ink receptivity from the beginning of the printing operation. The plate finisher is excellent in stability over time and can be prepared easily with an inexpensive equipment.
