Abstract
Method of making a processing-free planographic printing plate comprising irradiating a plate surface comprised of a hydrophobic organic compound capable of being converted, upon exposure to radiation, from hydrophobic to hydrophilic, in an image pattern and thereby selectively converting said surface, in the image pattern, from hydrophobic to hydrophilic. Alternatively, the image pattern is allowed to remain hydrophobic while the non-image areas are rendered hydrophilic.
