    Abstract: A method of processing an on-press developable lithographic printing plate involving the removal of the overcoat after laser imaging and before on-press development is described. The plate comprises a substrate, an on-press ink and/or fountain solution developable photosensitive layer, and an overcoat. The laser imaged plate is mechanically stripped off the overcoat, and then developed with ink and/or fountain solution on a lithographic press. Such a process allows the use of overcoat to achieve faster photospeed and improved durability of the plate without having various issues as related to overcoat such as contamination to the fountain solution, difficulty to remove of certain overcoat, and limited white light stability.
