For the increase of printing productivity and the diversity of design, it is better to perform printing by dealing with offset printing and security printing as a single process as in [Fig10. Quality control of ticket printing]. However, if a printing unit is lengthened, scratch and a margin of graphic printing may not match up each other because of extending of paper or failure of margin adjustment between machines.

Accordingly, in conventional printing methods, printing is performed by still separating a graphic printing line and a security printing line. In this case, a graphic printing level of a scratch part is tended to decrease.
