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.

A method for modifying a surface of a printing plate, the method comprising:
- identifying a location of a pixel of an image at the surface, an ink being disposed at the location of the pixel;
- and
- irradiating the ink at the location of the pixel using a laser imaging system.
An image surface for a printing plate, the image surface comprising:
- a hardened ink layer at a location of a pixel of an image, the hardened ink layer being formed by an irradiation using a laser imaging system and being useable as a printing surface.
