ABSTRACT:
The present invention provides a method for making a lithographic printing plate having high sensitivity and high printing endurance by scanner-exposing which comprises subjecting a photographic photosensitive material comprising a support and, provided thereon, an unfogged internal latent image type silver halide emulsion layer to scanner-exposing, subjecting the exposed photosensitive material to non-tanning development in the presence of a nucleating agent, and then subjecting the silver halide portion of the emulsion layer to an oleophilizing treatment.
