Abstract
A method for modifying an image surface of a printing plate includes identifying a location of a pixel of an image at the image surface, an ink being disposed at the location of the pixel. The ink at the location of the pixel is then irradiated using a laser imaging system. The ink may be cured by the radiation so that it is hardened and useable to receive liquid ink and be used as a printing surface. The ink may be ablated and removed. Individual pixels of the image may be added or removed from the printing surface.
