Current situation of anti-counterfeiting printing technology at home and abroad

current situation of anti-counterfeiting printing technology at home and abroad because anti-counterfeiting printing technology is related to the market management of various countries, its development level is also different. Generally, the printing level of banknotes, securities and certificates is relatively high, the technology is difficult to popularize, the anti-counterfeiting effect is good, and there is financial support from the government, so new anti-counterfeiting technology is constantly applied to banknote printing. The printing anti-counterfeiting of civil goods is related to the awareness and financial resources of operators, so most of them use general anti-counterfeiting technology or a single anti-counterfeiting means. The development of anti-counterfeiting technology is relatively slow, and some aspects of the effect is not ideal

at present, the more advanced anti-counterfeiting technology was first used in the 1990 US $50 and US $100 banknotes, and the micro text is arranged around. This technology has low cost and simple process, and has been used in banknote printing in many countries. In addition, as a new generation of anti-counterfeiting technology, the design, plate making and printing of rectangular mesh patterns have also entered the practical stage, such as the Dutch 1990 25, 250 guilder banknotes. Holographic anti-counterfeiting technology and special equipment are used to make holograms in specific positions of banknotes. This technology is high cost and easy to identify, which greatly improves the anti-counterfeiting ability of banknotes. At present, it has been used in the new version of Austrian 5000 shilling banknotes

at present, the development of technology to prevent counterfeiting by using color copiers has made great achievements. For example, the use of photochromic ink is a kind of light that will make the copied color different from the original in order to achieve the purpose of anti-counterfeiting. In addition, there is a 6-Start lifting electric conditioning experimental space paper to prevent copying. Once this paper meets the light of the copier, it will change its color or make the hidden words appear, so as to achieve the anti-counterfeiting effect. For example, some countries in Japan, Finland and France can easily identify the authenticity of their currencies by using some special materials produced in their own countries to make paper

the safety line in banknote printing is also the focus of national research: for example, the windowed transmission safety line and the sinking and floating safety line adopted by Britain; The safety wire of some aluminizing processes developed by France; Biochemical anti-counterfeiting marks are a major breakthrough in the development of anti-counterfeiting technology. Recently, they have been successfully developed by a foreign biological research institution. The main reason is that the materials printed on self-adhesive marks are difficult to be trusted, so as to achieve anti-counterfeiting. It is understood that this technology has been developed in China and will soon be used in the market

Digital Deformation anti-counterfeiting technology has also been applied abroad. This technology is applicable to any printed matter that requires Arabic numerals. Deformation is realized by computer, and there is no law to follow. Recognition is also through the computer to prevent forgery

with the development of digital printing technology and electronic publishing technology, the anti-counterfeiting of digital information has also been paid more and more attention, so a new digital anti-counterfeiting technology - digital watermarking is gradually forming

many new anti-counterfeiting materials have been used in various countries, such as photosensitive inks for can printing, anti-counterfeiting inks for silk fabrics and plastics, and anti-counterfeiting inks for hygroscopic materials in combination with the problems in the utilization of current oilfield chemicals and the focus of technical research

China's new anti-counterfeiting technology has been continuously applied in commodities in recent years, and has played a certain anti-counterfeiting effect. At present, most provinces and cities in China have established anti-counterfeiting printing production enterprises, and the fastest-growing is in the southern coastal areas. As far as holographic technology is concerned, in less than 10 years, about hundreds of manufacturers came out and developed rapidly. China has entered the advanced ranks in many aspects. For example, in the aspect of laser holographic technology, there are anti-counterfeiting phantom lines and anti-counterfeiting encryption technology. In terms of ink technology, there are touch reversible inks (which can be used for plastic bag printing). Table 4, which has the dual characteristics of photosensitivity and temperature sensitivity, is the standard control ink for new and old materials of a certain Japanese automobile bumper, which can be printed on plastic, paper, wood, ceramics, glass, polyester film and other carriers. There are fingerprint printing ink, light storage ink, bleeding ink, bar code ink, etc. In addition, self checking and unpacking label technology and microcomputer coding technology have been used in domestic new products. The emergence of these new technologies undoubtedly opens up a broader market for the application of anti-counterfeiting technology

the application of anti-counterfeiting technology has adopted a variety of anti-counterfeiting comprehensive new technologies such as design, plate making, printing and materials in the 1990 edition of RMB in China, so it is not easy to be copied, and the anti-counterfeiting effect is good. New anti-counterfeiting technologies such as watermark paper and explicit and implicit fluorescent ink are also used in various certificates and VAT invoices

the feasibility of developing anti-counterfeiting printing technology products by printing enterprises can be summed up in the following four points:

1. The equipment used in anti-counterfeiting printing technology products is the existing various types of printing machines and plate making equipment of printing enterprises, which does not need more investment. The process of anti-counterfeiting printing technology is no different from that of books and periodicals, packaging and printing

2, many factories have specialized personnel in anti-counterfeiting technology or design composition of engraving and plate making

3, the materials used in anti-counterfeiting prints are mainly anti-counterfeiting ink and anti-counterfeiting paper. These two materials are not difficult to buy. If it is listed as a designated production enterprise of national anti-counterfeiting printing technology products, even the materials controlled by the state can be obtained

4, the market prospect of anti-counterfeiting printed matter is broad, the economic benefit is quite high, and there is no labor price standard at present, and its profit margin can generally reach 30% - 50%, or even higher

to sum up, it is feasible for printing enterprises to develop anti-counterfeiting printing products. By using existing equipment and adopting existing technology, anti-counterfeiting products can be developed and better economic benefits can be obtained immediately
