    Abstract: A method of developing a laser sensitive lithographic printing plate with ink and/or fountain solution is described. The printing member comprises on a substrate a photosensitive layer soluble or dispersible in ink and/or fountain solution and capable of hardening upon exposure to a laser. The plate is exposed with a laser, deactivated, and then on-press developed with ink and/or fountain solution. Alternatively, the plate is developed with ink and/or fountain solution or the like off press, and then mounted on press for lithographic printing. The deactivation or off-press development allows the plate to be handled on press under white light or other light which is unsafe for a non-deactivated plate.

    Abstract: The invention provides a planographic printing plate precursor that is writable by laser exposure and is composed of a support, a photosensitive recording layer formed on the support, and a backcoat layer containing an epoxy resin, the backcoat layer being formed on the side of the support opposite to the photosensitive recording layer side; and a stack of the planographic printing plate precursors. According to the invention, scratches on the photosensitive recording side of the planographic printing plate precursor can be prevented when brought into contact with another planographic printing plate precursor in the stack without interleaving slip sheets, and productivity in a plate making process can be improved.
