Photoconductive waterless lithographic masters are provided which generate prints of improved contrast. The method comprises forming an image on a non~imaged master comprising an intermediate photoconductive layer, a conductive substrate, and an abhesive ink releasing silicone surface layer, the imaging comprising primary charging the master, selectively illuminating said master with an image pattern to effect charge migration, secondary charging said master, uniformly illuminating said master wherein a developable electrostatic latent image is formed on the exposed surface of said abhesive layer, and develop~ ing the image by deposition of marking material.
