Looking forward to the development of China's digital publishing industry, it still faces many problems such as various formats, product prices, business models, settlement and user experience. 20 1 1 capital publishing copyright work will accelerate the transformation of development mode, take mechanism innovation as a breakthrough, deepen reform, speed up resource integration, promote the integration of high-tech and publishing industry, innovate and improve the cultural service system of press and publication, optimize management mode, improve service level, and strive to create a new situation in capital publishing copyright work. By the end of 20 10 and10/,Beijing's press and publishing industry had achieved a revenue of 4661700 million yuan, a year-on-year increase of 9.45%. Total assets reached 935 15 billion yuan, up 8.74% year-on-year; The total profit is 3.059 billion yuan; Employees11more than 5,800 people. The total revenue of the press and publishing industry ranks fourth among the nine major fields of cultural and creative industries in the city. The following trends may appear in the future: 1, large and medium-sized publishing institutions operate in an integrated manner; 2. The 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 organizations are emerging, mainly in the form of the Internet; 5. Reader manufacturers open online bookstores; 6. Change from traditional channels to electronic channels; 7. Operators enter the whole process of digital publishing; 8. There will be more subdivided professional database service providers. The development of these trends and the solution of problems will be based on one theme: cooperation. The goal of cooperation is1+1=11. Please note that it is not 1+ 1=2, but 1 1, hoping to get more value. For industries that develop in geometric series, only greater value can be called value. To this end, we still need to do a lot of painstaking and meticulous work, such as * * * establishing a constructive alliance, exploring how digital publishing can be integrated with publishing institutions, formulating practical digital publishing strategic plans, standardizing business models and market strategies, and further clarifying partners. 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 point of view, "making partners more valuable" has practical significance, and it is bound to become an important topic for the development of digital publishing industry in China in the future. Anti-counterfeiting industry is an important industry to support and promote the development of market economy. The rampant counterfeit and shoddy goods and constant market fraud have become important factors restricting the sustained, rapid and healthy development of China's national economy. Due to counterfeiting, the products of a large number of well-known 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 fake and shoddy goods in China ranges from 1000 to120 billion yuan, accounting for 1% to 1.5% of the gross national product. Every year, the national profits and taxes are lost due to fraud, and the banking system is defrauded of more than 20 billion yuan by fake documents and 50 billion yuan by fake customs declarations. Anti-counterfeiting industry is a direct industry to fight against counterfeit and shoddy goods. China's anti-counterfeiting technology has rapidly expanded from a few application fields, such as RMB and certificates, to daily-use products, intellectual property protection and other fields. More and more famous product manufacturers, intellectual property owners and managers of various bills, certificates, securities, archives and commodity labels have adopted anti-counterfeiting technology in their own fields to prevent the intrusion of counterfeiting and protect the interests of enterprises and consumers. According to statistics, there are thousands of enterprises and institutions engaged in the research, production and sales of anti-counterfeiting technology products in China, and the annual output value of anti-counterfeiting products in China has increased from tens of millions of yuan in the early 1980s to tens of billions of yuan. In the next three to five years, the anti-counterfeiting industry will become a new economic growth point, and its annual output value is expected to be around 1000 to150 billion yuan. The commonly used technology, relief pattern anti-counterfeiting technology, is a special technology that uses special means to make different special textures for layout components such as background colors, characters, patterns and images. It can not only play an anti-counterfeiting role, but also play a decorative role, and is an ideal technology for the layout design of certificates and tickets. Because the design can't be repeated, it can't be scanned into the original picture and can't be copied. Micro-anti-counterfeiting technology Micro-anti-counterfeiting printing technology adopts the most advanced digital image replication technology. Its principle is to print patterns or characters on the surface of documents in a miniature way, and the images can be reproduced realistically through a magnifying glass. Paper security paper is the material basis for printing all kinds of securities. Some special papers made by special processes basically have anti-counterfeiting characteristics. The anti-counterfeiting technologies used in special paper mainly include: as a new development in the field of anti-counterfeiting technology, anti-counterfeiting paper has the following advantages. First of all, it makes the holographic pattern directly on the paper and removes the plastic information layer, so it is unlikely to be copied. Secondly, the patterns on this kind of anti-counterfeiting paper can be designed and made according to the requirements of merchants, and it can produce papers with different textures and weights (70g ~ 400g, such as coated paper, cardboard and cardboard), and it can also be offset printed and screen printed like ordinary paper, which is reliable and convenient. Thirdly, the price of this kind of anti-counterfeiting paper is only slightly higher than that of ordinary composite gold and silver cardboard, which is only one tenth of the price of holographic anti-counterfeiting trademark, and it saves the labor cost of labeling and is easily accepted by merchants. Fourthly, the products directly packaged with this laser anti-counterfeiting paper can not only play an anti-counterfeiting role, but also be very beautiful. Fifth, holographic paper will gradually replace laser holographic products containing plastic films, because it can be weathered in soil and will not cause environmental pollution. Some manufacturers of cigarettes, wine, cosmetics and food have begun to try 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. Watermark paper Watermark paper can be made into paper by technical means in the manufacturing process. These patterns are not easy to see under normal circumstances and can only be seen under strong light. Most of the RMB issued in China is printed on watermark paper. Watermark is still recognized as an effective anti-counterfeiting technology by anti-counterfeiting experts all over the world in the era of advanced technology, and continues to be adopted and developed by various countries. Most countries' banknotes, important international archives, facilities drawings and various tickets are also printed with watermark paper. For example, in the new version of $65,438+000 banknote of 65,438+096, the watermark of "Franklin" is adopted, and the watermarks of "Tiananmen Square" and "* * *" are large denomination RMB banknotes in China. Watermarking has been widely used in other papers except paper money. Watermark has fixed, unfixed and semi-fixed positions in paper. The production technology of water-printed paper was invented by Italian paper experts in 13 century. Because it involves complicated technological processes such as design, carving, netting and papermaking in the manufacturing process, counterfeiters are often at a loss. Checking the watermark is also one of the most effective means to identify the authenticity. Of course, it is not economical to use a lot of watermarks in packaging and decoration at this stage. An ink is made of special materials, and a watermark-like mark is printed on ordinary coated paper, which is very similar to the watermark effect. Anti-counterfeiting additive The so-called anti-counterfeiting additive is a special additive made by adding anti-counterfeiting materials with special properties to ink binders and processing them through special processes. The anti-counterfeiting additives developed and applied in China can be divided into 10 categories, which are described respectively. The specific implementation is mainly to add anti-counterfeiting additives to tickets, product trademarks and packaging paper layers by using special coating machines or other equipment. This anti-counterfeiting technology has the characteristics of simple implementation, low cost, good concealment, bright color, convenient inspection (even hand temperature can change color) and strong reproducibility, and is the first choice for anti-counterfeiting technology of banknotes, tickets and trademarks in various countries. 1, ultraviolet fluorescence anti-counterfeiting technology, special ink that can emit visible light (400-800 nm) under ultraviolet (200-400 nm) irradiation. According to the wavelength of excitation light source, it can be divided into short-wave ultraviolet excitation fluorescent anti-counterfeiting ink (excitation wavelength is 254nm) and long-wave ultraviolet laser fluorescence anti-counterfeiting ink (excitation wavelength is 365nm). According to the color of ink, it can be divided into colored fluorescent ink and colorless fluorescent ink. Among them, there are three kinds of commonly used fluorescent materials according to their components. First, organic fluorescent materials are large-yoke unsaturated molecules, which are mostly excited by sunlight and used for decoration with obvious colors, with poor fluorescence stability and easy oxidative decomposition; Secondly, inorganic fluorescent materials synthesized at high temperature are luminescent materials for fluorescent screens and fluorescent tubes, which have good radiation resistance and high stability, but are difficult to disperse in oily media. High synthesis difficulty and poor water resistance; 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 medium, colorless in visible light, and have strong fluorescence effect under ultraviolet excitation. 2. Anti-counterfeiting technology of sunlight excitation discoloration, which can emit visible light (400 ~ 800 nm) in sunlight. This kind of anti-counterfeiting technology appears to be discolored by the action of the sun, but it is also discolored by ultraviolet radiation in essence. These anti-counterfeiting technologies developed and applied by the company can change color under the irradiation of sunlight (or ultraviolet rays), can change from colorless to purple, blue, yellow and other colors, and can also be designed to change from colored to colorless, which is a rookie and wonderful work in anti-counterfeiting materials. 3. Heat-sensitive anti-counterfeiting technology can change color under the action of heating. According to the different temperature required for color change, it can be divided into hand temperature color change anti-counterfeiting technology and high temperature color change anti-counterfeiting technology. Hand temperature color-changing anti-counterfeiting technology refers to the color-changing effect at 34 ~ 36℃. According to the different color-changing methods, it can be divided into single color-changing reversible, multi-color-changing irreversible and multi-color-changing irreversible heat-sensitive anti-counterfeiting technologies. At present, China has developed five hand temperature monochrome reversible anti-counterfeiting technologies. Color changing methods include: rose becomes colorless, purple becomes colorless, blue becomes colorless, green becomes colorless, orange becomes colorless, and can also be designed into other colors; There are three reversible anti-counterfeiting technologies with single color change at high temperature. Color changing methods include: powder turns blue, yellow turns red, red turns black, etc. Thermochromic substances can be divided into inorganic salts, coordination compounds, organic substances (dye molecules) and liquid crystal polymers. 4. Reactive color-changing anti-counterfeiting technology Various chemical substances added to paper can produce various chemical reactions under certain conditions, thus changing the color of paper and achieving the purpose of anti-counterfeiting. As a part of heat-sensitive anti-counterfeiting technology, pressure-sensitive anti-counterfeiting technology and humidity-sensitive anti-counterfeiting technology belong to color-changing anti-counterfeiting technology. In addition, adding acid-base indicator to paper as trademark printing can change the color of paper when encountering color-changing agent, thus achieving the purpose of anti-counterfeiting. 5. Magnetic anti-counterfeiting technology is a special anti-counterfeiting technology made by mixing magnetic iron oxide powder into paper. At present, it is mainly used to print magnetically encoded characters and symbols of bank bills, with the function of recording and storing information. Put the ticket printed with the magnetic code into the magnetic code reader to identify the authenticity. If used properly in packaging and decoration, it can have strong security and anti-counterfeiting. 6. Droplet disappearance technology This anti-counterfeiting technology is a mixture of substances that can produce biochemical reactions. This additive can be used to mark the packaging and printed matter that need anti-counterfeiting, and then the chemical reagent can be selected according to the formula. When using methods such as slight heat, wetting and rubbing, words or patterns will be exposed. Due to the complex chemical composition of additives, it is very difficult to forge, and this anti-counterfeiting technology has been adopted in some confidential documents and important tickets. It is the simplest and easiest to operate nano-scale materials in domestic anti-counterfeiting detection. When recognizing, only a drop of water is needed to smear the logo, and the pattern disappears. The pattern is naturally restored and reversible after water drying, which is an advanced anti-counterfeiting technology in China. 7. Liquid crystal anti-counterfeiting technology adds a compound with crystallization performance to the ink. Under the influence of weak current and temperature, liquid crystals show alternating patterns and colors due to lattice changes. Packaging and decoration products printed with this ink can react with the change of temperature. If it is used to print a calendar, it will show different colors with the change of temperature in four seasons. It is a new ink material with great vitality and needs to be developed. When it is popularized in the field of packaging and decoration, its anti-counterfeiting effect is immeasurable. 8. Printing spot color ink Printing ink is a mixture of pigments, fillers and binders. Among them, the choice of pigment composition is an important factor to determine the hue and vividness of printed matter. Ink color matching is a very complicated problem. The differences in chromaticity and brightness between some organic pigments and inorganic pigments in nature and some inherent colors cannot be realized by artificial synthesis. The same ink produced by different ink factories has different colors in each batch. Therefore, some manufacturers of packaging and decoration products with large consumption fix their products in some large-scale and technologically advanced printing plants for printing, and at the same time customize and print the special ink for each product in the ink factory, and the formula is confidential. Laser Anti-counterfeiting "Laser Anti-counterfeiting", also known as "laser anti-counterfeiting", uses laser holographic technology to print unique patterns or characters on metal films. These patterns or characters can see various diffraction patterns from different angles. Adding a laser anti-counterfeiting label to a product or package makes the manufacturing process of the laser anti-counterfeiting label more complicated, and the plate-making cost is higher, and the original diffraction pattern on the laser anti-counterfeiting label is not easy to be copied again, thus effectively cracking down on counterfeiting. Commodity bar code, a bar code anti-counterfeiting technology, is a kind of code of commodities, which is designed by human beings for the effective management of computers and other commodities. If commodity technology can be used reasonably, including selecting the carrier, printing method, printing machine and printing position of barcode, it is possible to make commodity barcode technology have anti-counterfeiting function. Code anti-counterfeiting identification and telephone identification system Code anti-counterfeiting identification and telephone identification system (800 telephone inquiry anti-counterfeiting) is to set a random password on each product, and archive all the records of all product networking in the anti-counterfeiting data center library, so that consumers can use telephones, computers and other tools to check whether the password is correct and identify the authenticity of products. This anti-counterfeiting technology is implemented on the same object to achieve high anti-counterfeiting. The most typical example is paper money, such as RMB, which uses seven anti-counterfeiting methods. Therefore, various chemical anti-counterfeiting technologies should also be combined with other anti-counterfeiting technologies to improve the anti-counterfeiting efforts of brand-name products.
