An improved presensitized printing plate comprises at least one metal working surface, a cobalt layer electroplated on the outer working surface of said at least one metal working surface, and a coating of light sensitive material directly deposited on said cobalt layer. A method is also described which makes use of metallic cobalt for the preparation of presensitized printing plates in order to provide layers that are in themselves adherent to light sensitive materials without the need of using adhesives, and are useful for directly depositing light sensitive coatings thereon.
