At present, gravure (photographic printing plate) and offset anti-counterfeiting inks have been developed to meet the printing requirements of various patterns of stamps and the printing process requirements of different stamps. Like the "Yellow River Hukou Waterfall" mini-print stamps printed and issued before, a warm-tone "yellow ink glows red" encrypted gravure ink was used in the printing. The printed mini-sheets looked unchanged under normal light. ; But under the excitation of the ultraviolet lamp, the stamp pattern can give off a golden-red brilliance, which plays a role of anti-counterfeiting. It is not difficult to see from this successful combination that anti-counterfeiting ink should be organically applied in the design of postage stamps according to the characteristics of stamp prints, not only to achieve anti-counterfeiting purposes, but also to make prints have better artistic effects. In the research work of stamp anti-counterfeiting technology, we realized that anti-counterfeiting must be "two high and one strict", that is, anti-counterfeiting technology should be high-tech and high-input technology. The use of high-tech and increased investment in development funds can be copied. Increase the difficulty.
China's investment in the development of stamp printing anti-counterfeiting technology is quite large. "Strict" means strict management of anti-counterfeiting technology and anti-counterfeiting materials, without outflow or abuse, otherwise the vitality of its anti-counterfeiting technology will be greatly shortened. Any anti-counterfeiting technology and anti-counterfeiting materials are not once and for all, especially in today's rapid technological development. Therefore, the research work on stamp anti-counterfeiting technology for the secure printing of stamps cannot be stopped for a moment.
