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.
