Nowadays, many people are blinded by false certificates and false documents. Although it is hateful that swindlers ignore national laws and endanger people's lives, those who are cheated will inevitably have some responsibility for neglecting anti-counterfeiting technology. Today, let's learn about the paper anti-counterfeiting technology, so as to protect their legitimate interests.
1. Anti counterfeiting paper
As a new development of anti-counterfeiting technology, anti-counterfeiting paper has the following advantages. In the first place, it is possible to copy the hologram directly on the plastic layer.
Secondly, the pattern on the anti-counterfeiting paper can be designed and plate-making according to the requirements of the merchants, so as to produce the paper with different texture and weight (70g-400g), such as coated paper, cardboard and paperboard. It can also be used for offset printing and silk screen printing like ordinary paper, which is reliable and convenient.
Third, the price of this kind of anti-counterfeiting paper is only slightly higher than that of ordinary composite gold and silver card paper, which is only one tenth of the price of holographic anti-counterfeiting trademark. It also saves the labor cost of labeling and is easy to be accepted by businesses.
Fourth, the products packaged with this laser anti-counterfeiting paper can not only play an anti-counterfeiting role, but also be very beautiful.
Fifthly, since the waste holographic paper can be weathered in the soil and will not cause environmental pollution, it will gradually replace the laser holographic products containing plastic film.
At present, some cigarette, wine, cosmetics, food manufacturers have begun to use laser holographic anti-counterfeiting paper, and achieved good economic benefits. It is expected that this new anti-counterfeiting packaging material will have a broad market.
2. Watermark paper
In the manufacturing process of watermark paper, we can use technical means to put the required logo and pattern into the paper. These patterns are not easy to see under normal circumstances, and can only be seen when facing strong light. Most of the larger denominations of RMB issued in China are printed with watermark paper. In today's era of advanced science and technology, watermark is still recognized as an effective anti-counterfeiting technology by anti-counterfeiting experts all over the world. It continues to be adopted and developed in various countries. Banknotes, important international documents, facility drawings and various tickets of most countries are also printed with watermark paper. The position of watermark in paper has fixed, unfixed and semi fixed.
The production technology of watermark paper was invented by Italian papermaking experts in the 13th century. Because it integrates the complex process of design, carving, net making and paper making in the manufacturing process, the counterfeiters are often at a loss. Checking watermark is also one of the most effective means to identify true and false. Of course, it is not economical to use a lot of watermarks in packaging decoration at this stage. A kind of ink is developed with special materials, and the imitation watermark mark is printed on common coated paper, which is very similar to the watermark effect.
3. Safety line
Safety line refers to a gold or plastic line placed in the middle of the paper during papermaking. The safety line was first used with special gold thread, and now plastic thread is used, and has developed into various types, such as micro letter safety line, fluorescent safety line, etc. The shape of the safety line includes straight line, wave shape, zigzag shape, etc.
In recent years, with the rapid development of high technology, papermaking technology has made great progress after integrating other technologies. There are a variety of paper varieties, such as: business card paper, pearlescent paper, laser iris paper, gold foil and silver foil formed by the combination of metal and paper, embossing paper and refraction paper formed by reprocessing. If we can make rational use of their performance and characteristics, and control the purchase channel, as anti-counterfeiting printing paper, the effect and force produced can not be underestimated.
4. Red and blue fibers or color dots
In the process of papermaking, red and blue fibers or colored chips (dots) are mixed into the pulp, or scattered on the surface of the paper before the paper is shaped, and there is fluorescence reflection under ultraviolet radiation. Red and blue fibers and color dots have fixed position and unfixed position in the paper.
