Anti-counterfeiting printing is a comprehensive anti-counterfeiting technology, (National 315 Product Anti-Counterfeiting Inquiry Center) is a branch of special printing. Refers to the use of printing means to prevent imitation, duplication or counterfeiting without the permission of the owner. Basic introduction Chinese name: anti-counterfeiting printing Foreign name: fangweiyinshua refers to: a comprehensive anti-counterfeiting technology including: anti-counterfeiting design and plate making technology mainly includes: engraving plate making computer design pattern introduction, prospects, common technology, introduction Printing anti-counterfeiting technology is a Comprehensive anti-counterfeiting technology, including anti-counterfeiting design and plate making, sophisticated printing equipment and supporting inks, papers, etc. From a purely printing technology perspective, printing anti-counterfeiting technologies mainly include: engraving and plate making, computer-designed pattern, gravure printing, rainbow printing, pattern docking, double-sided printing technology, multi-color wiring printing, multi-color overprinting, and microprinting. technology, refractive latent images, invisible images and image-obfuscated printing. Prospects The development of China's digital publishing industry still faces various problems such as formats, product prices, business models, settlement, and user experience. In 2011, the capital's publishing copyright work will accelerate the transformation of development methods, use mechanism innovation as a breakthrough, continue to deepen reforms, accelerate resource integration, promote the integration of high-tech and publishing industries, innovate and improve the press and publishing public cultural service system, and finally Improve the *** management model, improve service levels, and strive to create a new situation in the capital's publishing and copyright work. As of the end of November 2010, the revenue of the news and publishing industry in Beijing reached 46.617 billion yuan, a year-on-year increase of 9.45%; total assets reached 93.515 billion yuan, a year-on-year increase of 8.74%; total profits were 3.059 billion yuan; and there were more than 115,800 employees. The total revenue of the news and publishing industry ranks fourth among the city's nine major cultural and creative industries. The following trends are likely to emerge in the future: 1. Integrated operation of large and medium-sized publishing institutions; 2. Cooperation between publishing institutions and technology providers will be further deepened; 3. Small and medium-sized publishing institutions will take the road of service outsourcing; 4. New digital publishing Institutions continue to emerge, mainly in the form of the Internet; 5. Reader manufacturers open online bookstores; 6. Traditional channels are fully transformed into electronic channels; 7. Operators enter the full-process digital publishing; 8. More subdivisions will appear Professional database service provider. The development of these trends and the solution of problems will be based on one theme: cooperation. The goal of cooperation is 1+1=11. Please note that it is not 1+1=2, but 11, in the hope of obtaining greater value. For an industry that develops in a geometric progression, only greater value can be called value. To this end, we still have to do a lot of hard and detailed work, such as jointly forming a constructive alliance, exploring how to integrate digital publishing more deeply with publishing institutions, formulating a realistic digital publishing strategic plan, and standardizing business models and markets. strategies, and further clarify partners, etc. Only in this way can we further clarify what we want, what we can bring to our partners, and what our cooperation can bring to the industry. From this perspective, "making partners more valuable" has practical significance and will surely become an important topic in the future development of China's digital publishing industry. The anti-counterfeiting industry is an important industry that supports and promotes the development of market economy. Counterfeit and shoddy goods are rampant and market fraud continues, which has become an important factor restricting the sustained, rapid and healthy development of China's national economy. Due to counterfeiting, the products of a large number of famous and high-quality enterprises in China have been impacted to varying degrees, disrupting the normal production order of enterprises and seriously damaging the legitimate rights and interests of enterprises and consumers. According to statistics, the annual output value of counterfeit and shoddy goods in China is between 100 billion and 120 billion yuan, accounting for 1% to 1.5% of the gross national product. Every year, due to counterfeiting, the country loses more than 60 billion yuan in profits and taxes, and the banking system is damaged by counterfeiting. Document fraud amounts to more than 20 billion yuan, and customs' false declarations defraud foreign exchanges amounting to 50 billion yuan every year. The anti-counterfeiting industry is an industry that directly fights against counterfeit and shoddy goods. China's anti-counterfeiting technology has rapidly expanded from being limited to a few applications such as RMB and documents to daily products, intellectual property protection and other fields. More and more famous product manufacturers, owners of intellectual property rights, and managers of various bills, certificates, securities, archives, and product labels are adopting anti-counterfeiting technology in their own fields to prevent the intrusion of counterfeiting and protect their products. Business and consumer interests.

According to statistics, there are thousands of enterprises and institutions in China engaged in the research, production and sales of anti-counterfeiting technology products. The annual output value of China's anti-counterfeiting products has grown from tens of millions of yuan in the early 1980s to tens of billions of yuan. In the next 3 to 5 years, the anti-counterfeiting industry will also become a new economic growth point, and its annual output value is estimated to be around 100 to 150 billion yuan. Commonly used technologies Relief pattern anti-counterfeiting technology Pattern technology is a special technology that uses special means to create different special textures on the background color, text, pattern, image and other layout components. It can not only prevent counterfeiting, but also play a decorative role. It is an ideal technology for the layout design of documents and tickets. Because its design cannot be repeated, it cannot be scanned into the original image and cannot be counterfeited. Miniature anti-counterfeiting technology Miniature anti-counterfeiting printing technology adopts today's most cutting-edge digital image reproduction technology. Its principle is to print patterns or text on the surface of the document in a miniature manner, and the image can be reproduced realistically through a magnifying glass; Paper anti-counterfeiting paper is used to print various securities The material basis is that some special papers made with special processes basically have anti-counterfeiting characteristics. The main anti-counterfeiting technologies used in special papers are: Anti-counterfeiting paper is a new development in the field of anti-counterfeiting technology. Its advantages are as follows. First of all, it makes the holographic pattern directly on the paper, removing the plastic information layer, so there is little possibility of being copied. Secondly, the patterns on this kind of anti-counterfeiting paper can be designed and plate-made according to the requirements of the merchants, and paper of different textures and weights required by the merchants (70 grams to 400 grams, such as coated paper, cardboard, cardboard, etc.) can be produced. Like ordinary paper, it can be used for offset printing, screen printing, etc., which is reliable and convenient. Thirdly, the price of this kind of anti-counterfeiting paper is only slightly more expensive than ordinary composite gold and silver cardboard, and is only equivalent to one-tenth of the price of holographic anti-counterfeiting trademarks. First, it saves the labor cost of labeling and is easy to be accepted by merchants. Fourth, products directly packaged with this laser anti-counterfeiting paper can not only play an anti-counterfeiting role, but also be very beautiful. It can be weathered in the soil and will not cause environmental pollution. Therefore, it will gradually replace laser holographic products containing plastic films. Some manufacturers of cigarettes, wine, cosmetics, and food have begun to initially try to use laser holographic anti-counterfeiting paper. It has achieved good economic benefits. It is expected that this new type of anti-counterfeiting packaging material will have a broad market. During the manufacturing process of watermark paper, technical means can be used to make the required logos, patterns, etc. into the paper. It is not easy to see under normal circumstances and can only be seen clearly under strong light. Most of the larger denominations of RMB issued by China are printed on watermark paper. In today's era of advanced science and technology, watermarks are still recognized by anti-counterfeiting experts from all over the world. Effective anti-counterfeiting technology continues to be adopted and developed by various countries. Banknotes, important international archives, facility drawings and various tickets in most countries are also printed on watermark paper. For example, the new version of US$100 paper in 1996 was used. In addition to being used in currency paper, watermarks such as "Tiananmen" and "***" have been produced on China's large-denomination RMB paper. Use. The position of watermark in the paper is fixed, unfixed and semi-fixed. The production process of watermark paper was invented by Italian papermaking experts in the 13th century because it integrates design, engraving, etc. in the manufacturing process. Complex processes such as screen making and papermaking often make counterfeiters helpless. Checking watermarks is also one of the most effective ways to identify authenticity. Of course, it is not economical to use extensive watermarks on packaging decorations for anti-counterfeiting at this stage. An ink is developed using special materials to print imitation watermarks on ordinary coated paper. The effect is very similar to watermarks. Anti-counterfeiting additives The so-called anti-counterfeiting additives are anti-counterfeiting materials with special properties added to the ink binder and processed through special processes. The anti-counterfeiting additives developed and applied in China can be divided into 10 categories, which are explained separately. The specific implementation mainly uses special coating machines or other equipment to add anti-counterfeiting additives to the layers of tickets, product trademarks and packaging paper. Anti-counterfeiting technology is characterized by simple implementation, low cost, good concealment, bright colors, convenient inspection (even the color can be changed by hand temperature), and strong reproducibility. It is the preferred anti-counterfeiting technology for banknotes, tickets and trademarks in various countries. 1. Ultraviolet fluorescent technology. Photo anti-counterfeiting technology is a special ink that can emit visible light (400~800nm) under ultraviolet light (200~400nm) irradiation.

According to the wavelength of the excitation light source, it can be divided into short-wave ultraviolet laser-excited fluorescent anti-counterfeiting printing ink (excitation wavelength 254nm) and long-wave ultraviolet laser fluorescent anti-counterfeiting printing ink (excitation wavelength 365nm). According to the color of the ink, it is divided into two types: colored fluorescent ink and colorless fluorescent ink. There are three main types of commonly used fluorescent materials classified according to their composition. First, organic fluorescent materials are unsaturated molecules with large yoke. They are mostly excited by sunlight and used for decoration with obvious colors. They have poor fluorescence stability and are easy to oxidize and decompose; second, inorganic fluorescent materials synthesized at high temperatures. Optical materials are luminescent materials used in fluorescent screens and fluorescent tubes. They have good radiation resistance and high stability, but are difficult to disperse in oily media. The synthesis is difficult and the water resistance is poor; thirdly, chemically synthesized rare earth organic complexes are used as fluorescent materials. Conventional organic rare earth fluorescent complexes are simple to prepare, easy to disperse, dissolve, and refine in oily media, are colorless under visible light, and exhibit strong fluorescent effects under ultraviolet light excitation. 2. Sunlight-induced discoloration anti-counterfeiting technology: Anti-counterfeiting technology that can emit visible light (400~800nm) under sunlight. This anti-counterfeiting technology appears to change color due to the action of the sun, but in fact it also changes color due to ultraviolet radiation. The company has developed and applied several such anti-counterfeiting technologies that will change color under sunlight (also under ultraviolet light). They can change from colorless to purple, blue, yellow, etc., or they can be designed to change from colored to colorless. Change is a new and wonderful thing in anti-counterfeiting materials. 3. Thermal anti-counterfeiting technology is an anti-counterfeiting technology that can change color under the action of heating. According to the different temperatures required for discoloration, it can be divided into hand-warm discoloration anti-counterfeiting technology and high-temperature discoloration anti-counterfeiting technology. Hand-warm color-changing anti-counterfeiting technology means that the color-changing effect can occur at a temperature of 34 to 36°C. According to the difference in color change methods, it can be divided into single color change reversible, multi color change irreversible and multi color change irreversible thermal anti-counterfeiting technology. China has now developed five hand-warm single-color reversible anti-counterfeiting technologies. The color-changing methods are: rose red to colorless, purple red to colorless, blue to colorless, green to colorless, orange to colorless, and can also be designed. It can be colored into various other colors; three high-temperature single-color reversible anti-counterfeiting technologies, the color-changing methods are: pink to blue, yellow to red, red to black, etc. Thermochromic substances can be divided into inorganic salts, coordination compounds, organic substances (dye molecules) and liquid crystal polymers. 4. Reactive discoloration anti-counterfeiting technology Various chemical substances added to paper can undergo various chemical reactions under certain conditions, thereby causing the paper to change color and achieve anti-counterfeiting purposes. As part of heat-sensitive anti-counterfeiting technology, pressure-sensitive color-changing anti-counterfeiting technology and moisture-sensitive color-changing anti-counterfeiting technology are all color-changing anti-counterfeiting technologies. In addition, acid-base indicators are added to the paper. After the trademark is printed, the color of the paper will change when it encounters the discoloration agent to achieve anti-counterfeiting purposes. 5. Magnetic anti-counterfeiting technology is a special anti-counterfeiting technology made by mixing magnetic iron oxide powder into paper. It is currently mainly used to print magnetically encoded text and symbols on bank notes, and has the function of recording and storing information. Put the magnetically coded ticket into the magnetic code reader to identify the authenticity. Properly used in packaging and decoration, it can have strong and safe anti-counterfeiting properties. 6. Anti-counterfeiting technology such as dripping disappearing technology is mixed with substances that can produce biochemical reactions. You can first use this additive to make an invisible mark on packaging and printed products that need to be anti-counterfeiting. Then, according to the formula, it can be targeted Select chemical reagents, and when operated with slight heat, wetting, friction, etc., the text or pattern will be revealed. Due to the complex chemical composition of this additive, it is very difficult to forge. Some top-secret files, important tickets, etc. have adopted this anti-counterfeiting technology. It is the simplest and easiest to operate nano-level material anti-counterfeiting in terms of anti-counterfeiting detection in China. During identification, you only need to apply a drop of water on the logo, and the pattern will disappear. After the water dries, the pattern will naturally recover. It is reversible and is the most advanced anti-counterfeiting technology in the country. 7. Liquid crystal anti-counterfeiting technology: Compounds with crystallization properties are added to the ink. Under the influence of weak current and temperature, liquid crystal displays light and dark patterns and colors due to changes in the crystal lattice. Packaging decorations printed with this ink can react with changes in temperature. If used to print calendars, it will show different colors as the temperature changes in the four seasons. It is a new type of ink material that is very viable and needs to be developed. If it is promoted and used in the field of packaging and decoration, its anti-counterfeiting effect is also immeasurable.

8. Printing spot color ink Printing ink is a mixture of color materials, fillers, connecting materials, etc. The component selection of the color materials is an important factor in determining the hue and brightness of the printed product. Ink color matching is a very complex problem. The differences in chroma, brightness and some inherent colors of some organic and inorganic pigments in nature cannot be achieved artificially. The colors of the same model of ink produced by different ink factories vary from batch to batch. Therefore, some manufacturers of large-volume packaging and decoration products have designated their products for printing at some large-scale and technologically advanced printing manufacturers. At the same time, they have customized special inks for each product printing at the ink factory. The formula is given by The ink factory is responsible for confidentiality. Laser anti-counterfeiting "Laser anti-counterfeiting", also known as "laser anti-counterfeiting", uses laser holographic technology to print unique patterns or words on metal films. These patterns or words can be seen in various diffraction patterns from different angles. Adding laser anti-counterfeiting labels to products or packaging. The production process of laser anti-counterfeiting labels is relatively complex and the plate making cost is high. Moreover, the original diffraction pattern on the laser anti-counterfeiting labels is not easy to be copied again, thus effectively combating of fraud. Barcode anti-counterfeiting technology Product barcode is a code for goods, which is designed by humans for effective management of computers and other goods. If we can rationally use product technology, including rationally selecting the carrier of the barcode, rationally selecting the printing method and printing machine, rationally selecting the printing position, etc., then it is possible to make the product barcode technology anti-counterfeiting. Code anti-counterfeiting mark and telephone identification system The code anti-counterfeiting mark and telephone identification system (800 hotline for anti-counterfeiting inquiry) sets a random password on each product and archives all records of all networked products in the anti-counterfeiting data center library, allowing consumers to Use telephone, computer and other tools to check whether the password is correct to identify the authenticity of the product. This anti-counterfeiting technology is implemented on the same physical object to achieve a high degree of anti-counterfeiting. The most typical example is banknotes, such as the RMB, which uses seven anti-counterfeiting methods. Therefore, various chemical anti-counterfeiting technologies should be combined with other anti-counterfeiting technologies to improve the anti-counterfeiting strength of famous brand products.
