PROBLEM TO BE SOLVED: To make the printing pressure of printing plate projections and a base plate small and uniform so that the uniformity of a printed film thickness may not be lowered even when the precision of a printing machine is not sufficient or when printing conditions are not uniform in high definition pattern printing. SOLUTION: In regard to a plastic letterpress printing plate used for letterpress printing wherein the ink applied on projections of an image pattern part is transferred onto a base, this high definition plastic letterpress printing plate is provided with a dummy pattern 2 which has the same thickness as the projections 3 of the image pattern part.
