Abstract

The National Printing Bureau of Japan has been developing new anti-counterfeiting technologies as a banknote printer. Some of our technologies have already been effectively introduced into Japan's new banknote series. Anti-counterfeiting technologies can be applied not only to banknotes but also to other security documents depending on desired features. In this presentation, I will introduce three of our newly developed overt and covert security techniques, which are intended for document security and brand protection, as well as banknotes. "Metallic View" is mainly for offset printing. "Copy Check" (micro-structural lines involving luminescence) is for plate making technology. "ImageSwitch" is for a new security solution which has unlimited printing applications. All three techniques create "latent images" (some of which may be better known as "carrier screen images") that are useful in preventing counterfeiting. While each of the techniques is effective by itself, all are more effective when applied together. Combining these techniques could make all security documents harder to copy using IT scanners, and provide cost-effective anti-counterfeiting solutions for all security users.
