PURPOSE:To obtain a color film for a lithographic printing plate having good adhesiveness and surface slipperiness by forming a cured film of a coating liquid having specific characteristics on a light transmissive film by a gravure roll having a specific area ratio in the cell part. CONSTITUTION:The coating liquid is coated on the light transmissive film by using the gravure roll, of which the area of the cell parts is 10-60% of the roll surface area. A PP, polyvinylidene chloride, etc., 1 having >=50% light transmittivity to active rays is used as the substrate film in this stage. A chlorinated PP soln. or the like which has 0.5-30poise viscosity, has form retentivity when dried or cured after coating and has >=50% transmittivity to the active lays is used as the coating liquid. The rugged film which permits the easy change of the surface shape and has high transparency and is adequate as the waterless lithographic printing plate is thus obtd.
