Abstract

A method of developing a lithographic printing plate, and a printing press, wherein a photosensitive (PS) coating on the plate is comprised of water insoluble active materials such that when the plate is developed the PS coating is mechanically removed from the background (non image) areas of the plate in a totally solid phase. There is no resin, dye, or colorant in the PS coating that will dissolve or disperse in either the fountain solution or the ink. A method and the press embodiments rely on the blanket and a film of ink between the blanket and the PS coating on the plate, to mechanically remove all the nonimage PS coating areas of the plate from the substrate as particles. The blanket then transfers all the removed particles onto the print media, whereby none of the coating dissolves or disperses in the ink emulsion or fountain water.
