ABSTRACT:
A cutting die is produced by a process of forming resist patterns corresponding to the shapes of low cutting edges and resist patterns corresponding to the shapes of high cutting edges on a metal plate and conducting an etching treatment on the metal plate, wherein the height of each of the cutting edges is varied by varying the width of the relevant resist pattern, varying the timing of removing the relevant resist pattern and applying or not applying sealing treatment thereto. This process enables easy production of a cutting die provided either with low cutting edges and high cutting edges or with embossing parts and high cutting edges. Further, the use of this cutting die enables simultaneous execution of full cutting and half cutting (or embossing) operations, so that labels, box development base papers and the like can be produced by a single process.
