Abstract
The present invention is a method and system for lithographic printing by controlling the surface energy of a printing plate to affect the hydrophilic and hydrophobic properties of the printing plate. These properties enable the ink to be applied to the printing plate in an image-wise manner and provides for rapid production of images on a recording medium. The lithographic printing plate may be rewritten repeatedly between printing jobs or may even be rewritten between individual recording media.
