PURPOSE: To provide a method for producing a die without need for an actual original and capable of being easily registered with a printed picture pattern in embossing.
CONSTITUTION: A negative film for resolving cyan (C), magneta (M), yellow (Y) and black (B) and a negative film for resolving black and white are formed from an original, and multicolor printing is applied to a printing plate prepared based on the negative film for resolving cyan (C), magenta (M), yellow (Y) and black (B). Meanwhile, a color resolving negative film having a large gradation difference is selected from the negative film for resolving cyan (C), magenta (M) or yellow (Y), the selected color resolving negative film is corrected to form a corrected color resolving negative film, and the corrected color resolving film and black-and-white resolving negative film are synthesized to prepare a synthetic line plate 1. The photosensitive resin 3 is irradiated with light through the line plate 1, exposed and developed to form a die 9 having a rugged pattern corresponding to the plate 1.
