ABSTRACT:
A method of preparing a lithographic printing plate, and the resulting printing plate, by applying an acidified oxidizing agent such as aqueous potassium permanganate solution to the toned electrostatic latent image on the photoconductive layer of an electrophotographic member to define water-receptive non-printing areas. The thus treated surface may be washed or further treated with conventional ferrocyanide ion containing fountain solutions or gum arabic, but only if desired.
