Abstract

PURPOSE: The information is printed, in such a way that more or less 30% irradiated light may be reflected, onto the printing subject which is printed with special color that reflects over 60% of the color at around the peak of light detector. Thus, optical hidden-printing becomes possible, enabling the application field expansion for information collecting system.
