PURPOSE:To inexpensively obtain a printing form good in dimensional accuracy and appearance within a short period, in reproducing a plurality of printing forms only partially different in contents to be printed, by a method wherein a recessed part is formed to a part different in content by a casting matrix mold and, after a printing form is fabricated by casting, the different part is subjected to manual engraving processing. CONSTITUTION:In reproducing at least two or more of printing forms only partially different in contents to be printed by one casting matrix mold, to parts different in contents in the casting matrix mold 20, for example, the parts corresponding to the product numbers 1a, 1b of a packing case, a recessed part 15 is preliminarily formed and, after a printing form 21 is fabricated by casting, the protruded part 16 formed to the parts different in contents to be printed is subjected to manual engraving by using a chisel to obtain an objective printing form excellent in dimensional accuracy and appearance. |
