FORGERY PREVENTION PAPER AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a forgery prevention paper suitable for improving the production efficiency and the yield in terms of production of the forgery prevention paper.

SOLUTION: The forgery prevention paper 1 is produced by printing information 3 to a two-color thermal paper 2 by a printer, and printing a forgery prevention element 4 to be like a ground tint to the two-color thermal paper 2 by a color different from a printing color of the information 3 with the use of the same printer. Thus the forgery prevention element 4 can also be printed by the same printer as that of the printing of the information 3. A display of the information 3 and the forgery prevention element 4 can be carried out by one printing process, and a conventionally executed printing process for the forgery prevention element is abolished.
