Dainippon Printing Co., Ltd. learns from the security printing process of securities printing and develops a new holographic anti-counterfeiting technology called FINEGRAM.
Commonly used in securities printing include the addition of color patterns that are difficult to imitate, Tang grass (Japanese silk or vine-like patterns on printed matter), and watermarks, which make subtle changes in the shape of printed dots, and anti-counterfeiting means such as mixing in tiny texts, and are even more popular in FINGRAM. True reproduction, therefore better than the previous holographic anti-counterfeiting technology.
