PROBLEM TO BE SOLVED: To simply determine that printing pressure is either of appropriate printing pressure or over printing pressure not relating to anilox roller pressure.SOLUTION: Two or more detectors 74a and 74b have different widths from each other and are set to be higher than the lowest projection part 76c in respective projection parts 76a-76c or set to be the same height in a letterpress C for printing that is made by a letterpress for printing preparation device and a letterpress for printing creation method. When a detector image and a solid part image are printed in a body to be printed by a printer and a printing method using the letterpress C for printing, whether printing pressure is appropriate printing pressure or not is determined by comparison between an optical concentration of two or more of the detector images and an optical concentration of the solid part image in a printing pressure determination device and a printing pressure determination method.
