Comparison of the Similarities and Differences Between the Printing Anti-counterfeiting Technology of Banknotes and Stamp

As a statutory circulation currency in China, the renminbi has used many sophisticated anti-counterfeiting technologies. Stamps, as a kind of valuable securities, are examples of advance payment for postal workers. With the development of science and technology, stamps also use many anti-counterfeiting technologies. Since the banknotes and stamps have different characteristics and their anti-counterfeiting is also different, the comparison of security against banknotes and stamps will be made below.

First, the same anti-counterfeiting technology for banknotes and stamps

1. Printed paper banknotes are printed with special banknote-printing paper. The texture feel is quite different from ordinary paper. At the same time, due to the characteristics of banknotes and the use of special techniques, such as the strong circulation of banknotes, banknote printing paper also has Tougher than usual. Most of the stamps used in recent years are red and blue fiber stamp paper. This kind of paper can only be produced by a few manufacturers because of its good anti-counterfeiting performance.

2. Engraving and gravure engraving Gravure requires artists to manually engrave them with steel knives. They also have high requirements for artists, so the security is also very good. The banknote stamps printed on the engravings are clear lines and have a strong three-dimensional effect. They are very popular with people. The new China old special-tickets are mostly carved, and they have been overprinted in recent years.

3. The watermark pattern watermark is used more often in banknotes, and foreign stamps are mostly used in stamps. And the watermark pattern of the banknotes is rich, such as characters, flowers, etc.; the stamp watermark is generally simple, such as a five-pointed star.

4. Microfilms There are more microfilms and fewer stamps.

Second, banknotes and stamps different anti-counterfeiting technology

1. Stamp special anti-counterfeiting technology

1) Tooth hole The anti-counterfeit tooth hole is unique to the paper money. Unlike the paper money, there are many special-shaped tooth hole stamps. They are all made with aps punch.

2) Fluorescent Printing and Fluorescent Ink Fluorescent printing and printing inks are also unique anti-counterfeiting technologies for stamps. More and more stamps now use this technology. Not only do they have anti-counterfeiting functions, but the stamp's artistry has also been improved.

2. Special anti-counterfeiting technology for banknotes

1)Magnetic Microtext Security Line The security line in the banknote banknote is transparent to the light, visible text, and the instrument is magnetically detected.

2) The number of light denomination ink denominations The text printed on the ink is perpendicular to the face of the ticket. It is a color, and is tilted at a certain angle and is another color.

3) The invisible denomination number is a kind of anti-counterfeiting technology used in engraving. Using the different directions of lines, special patterns can be formed.
