    Abstract: A method of processing an on-press developable lithographic printing plate with ink and/or fountain solution is described. The plate comprises on a substrate a photosensitive layer which is either capable of hardening (negative-working) or solubilization (positive-working) upon exposure to a laser, the non-hardened or solubilized areas of the photosensitive layer being soluble or dispersible in ink and/or fountain solution. The plate is exposed with a laser, heated to an elevated temperature, and then developed with ink and/or fountain solution on a lithographic press. The laser exposed plate is preferably heated by passing through a heating device or while mounted on a lithographic press before on-press development.

    Abstract: A method of processing an on-press developable lithographic printing plate involves the removal of overcoat by brushing or rubbing while in contact with water or an aqueous solution after imagewise exposure and before on-press development. The plate comprises a substrate, an on-press ink and/or fountain solution developable photosensitive layer, and a water soluble or dispersible overcoat. Preferably, the overcoat is incapable of being completely removed with ink and/or fountain solution on a lithographic press during roll up. Such a method allows the use of more durable overcoat for on-press developable plate.
