What is anti-counterfeiting security paper

Technical introduction
Paper anti-counterfeiting, that is, paper anti-counterfeiting technology. It is a new anti-counterfeiting technology based on extracting and recognizing the innate, unique and inimitable, cloned natural fiber texture of each paper as an anti-counterfeiting feature (ie, paper texture) to achieve anti-counterfeiting.
Anti-counterfeiting paper application
Different from the traditional anti-counterfeiting technology, the paper texture anti-counterfeiting technology does not use any artificially printed patterns or materials, but uses the natural anti-counterfeiting characteristics endowed by nature to the paper, that is, the three-dimensional distribution characteristic paper texture of the natural fiber texture of the paper. It is regarded as a natural anti-counterfeiting feature given to each piece of paper by nature (this feature is naturally unique, stable, random, and non-reproducible), and the paper pattern of each piece of paper is different, and criminals can not only clone one The paper pattern of paper, it is even more impossible to clone similar documents in large quantities by copying a paper pattern
Anti-counterfeiting paper classification
Anti-counterfeiting paper with security thread
It refers to placing a metal or plastic thread in the middle of the paper during the papermaking process. In the early days, special metal threads were used, such as polyester plastic threads, miniature letter safety threads, fluorescent safety threads, etc. As long as the shape is straight, it is worth a visit. It is mentioned that the latest 3D security thread technology is used in the new version of the US dollar bills circulated in 2011, which is the "3D security tape" on the right side of the US dollar Franklin's head portrait; it changes with the inclination angle of the hand, among which the bright blue security tape contains the United States The independent bell pattern and the 100 inscription will move back and forth, left and right. The security tape is embedded in the banknote, not printed.
watermark paper
It refers to paper with embossed, see-through, touchable images, etc. Among them, there are three kinds of watermarks: fixed watermark, semi-fixed watermark and non-fixed watermark.
Laser anti-counterfeiting paper
It refers to the combination of laser anti-counterfeiting technology and paper to make anti-counterfeiting paper. For example, using holographic anti-counterfeiting technology and special equipment, the holographic image is made in a specific position of the banknote to improve the anti-counterfeiting performance. For anti-counterfeiting technology, laser technology has been skillfully applied to paper.
Red and blue fiber silk, color dot encryption paper
It refers to the addition of red and blue colored fibers or colored small pieces (dots) into the pulp during papermaking, or sprinkled on the surface of the paper before the paper is not set, and it fluoresces under ultraviolet light, so that the finished paper is different from the paper itself. colored fibers.
chemical encryption paper
It refers to the addition of special compounds to the pulp or the addition of special compounds to the glue or the cloning of certain biological DNA molecular fragments when sizing the paper surface.
electrostatic recording paper
It means that the paper surface is coated with conductive layer and insulating layer paint, and can accept the voltage released from the needle electrode to destroy the insulating layer on the paper surface and form an electrostatic latent image with the conductive layer, so that the developer can be attached to the pattern when added. , and then heat-melted and fixed on the paper to produce a clear pattern.
Optical reading paper
Refers to the printing paper applied to the optical reading machine for reading text, the number is called OCR, and the special mark is called OMR, because the optical absorption or reflection is used to read, in order to avoid misreading, the paper is Smoothness, abrasion resistance, cleanliness, etc. have higher requirements.
Magnetic recording paper (MICR paper)
It refers to the surface of the paper coated with strong magnetic particles, and the paper can be printed with magnetic ink that can be recognized by the computer.
future development
At present, paper texture anti-counterfeiting technology is mainly used in bank bill/voucher management. In principle, "paper texture anti-counterfeiting technology" can be applied to anti-counterfeiting in many fields, such as commodity anti-counterfeiting. Among all commodity anti-counterfeiting, bank bills, as a special commodity, have the highest value and the most urgent demand. The average value of a bank draft is more than one million yuan, and some even reach tens of millions. The annual settlement volume of exchange certificates alone in my country reaches hundreds of trillions, and cases of counterfeit and cloned drafts are frequent. The emergence of paper texture anti-counterfeiting technology has solved the urgent needs of the financial system. And this anti-counterfeiting technology will be gradually extended to the anti-counterfeiting field of other commodities in the future.
