ABSTRACT:
This invention provides a method for making a lithographic printing plate of high resolving power and high printing endurance which comprises imagewise exposing a photoreceptor having a conductive layer and a printing sheet comprising a conductive support having thereon a dielectric non-photosensitive layer which are placed opposite to each other while applying a direct voltage between said conductive layer and said conductive support by a direct current source to form a positive electrostatic latent image on said non-photosensitive layer of the printing sheet and then subjecting the image to development and fixation.
