The seal is the main credence for holding rights and cashing materials or currency and plays an important role in the social activities in our country. In order to prevent and crack down on the criminal activities of forged seals, some anti-counterfeiting technologies have emerged in China in recent years. Since the State Council has provisions on the shape, size, printed characters, and patterns of official seals, existing anti-counterfeiting measures are basically microscopic changes that do not change the above-mentioned rules.
1, the image of the stamp on the security. (1) Microscopically changing certain features of standard fonts or reorganizing handwritten seal fonts to create a special laser engraving font for seals. (2) Under the premise of not changing the existing seal graphic and textual provisions, redesign subparagraphs, edges and other parameters, change the text character height, indirect, tilt, aspect ratio, pen width and other detailed features. (3) Adjust the edges of the five-pointed star to change or strictly specify its position and the relative position between the texts. Create a random security curve or characteristic pattern or an inscription on five stars. (4) Adding random points and moire, setting gaps and coding on the ring, randomly or according to the position of the dial on the hour hand. (5) Adding an integrated or separate hidden code, bar code, shadow, and even fingerprints, photos and graphic passwords. Invisible images need to be visualized and interpreted under ultraviolet light.
The above-mentioned engraving features should have a precision of 1 wire. After programming, it can be managed by computer and automatically recognized.
2, ink and ink pad security. It is mainly fluorescent anti-counterfeit printing ink pad (see security ink). Among them, there are color and colorless, the former is different from the colorant added, and the red, blue, and black colors are visible to the naked eye. The latter does not contain pigment, is not visible to the naked eye, or is slightly milky, so it is used only for invisible signs. Both need to be observed under ultraviolet light.
Seals have been used for computer storage management and can also be locally or nationally networked. Sealed computer automatic identification system and corresponding software have finished products entering the market.
