PROBLEM TO BE SOLVED: To display proper traveling property on an exposed surface plate under any condition by forming projecting parts projecting downward of a printing plate by partially bending a part to be a holding part at the time of mounting a printer for at least one side of the printing plate. SOLUTION: Projecting parts 12, 12 are formed by partially bending an end edge of a photosensitive planographic printing plate 11 formed by being bent in a zigzag shape downward for a side at prescribed intervals. The bottom surfaces of the projecting parts 12, 12 may be formed into a flat groove shape and a semicircle or a V-shape in cross section. The projecting parts 12, 12 which are swollen downward along the end edge of the photosensitive planographic printing plate 11 and are provided by a plurality of rows can be formed by being molded on the photosensitive planographic printing plate 11 cut into a prescribed dimension by molding press. |
