Anti counterfeiting technology of commercial paper printing 1. China's commercial paper printing has made remarkable achievements. With the rapid development of China's economy, especially the further popularization of computer technology application and electronic services, China's commercial paper printing industry has achieved unprecedented development. Statistics show that after more than ten years of development from scratch, China's commercial paper market has become an industry with an output value of more than 10 billion yuan, and it is also growing at a rate of 15% - 20% every year. At present, there are more than 1200 enterprises engaged in bill printing in China, including more than 300 enterprises installed with commercial bill rotary printing machines, and their businesses involve tax, banking, finance, insurance, securities, transportation, postal service, telecommunications, customs, logistics and other related industries. Its operation and service methods have been in line with international advanced service methods. The rapid development of bill printing technology has contributed to the financial circulation field, stabilizing social order and improving circulation efficiency; To promote information construction and improve management efficiency; It has provided a strong guarantee and laid a reliable foundation for cracking down on forged bills and economic crimes. 2、 Commercial paper printing technology still lags behind the market needs. The current tax reform has made tax invoices a hot spot. At present, many provinces and cities need new tax invoices, and some places lack the technology and production capacity to print new tax invoices. 2. For example, the nine enterprises that can print ordinary tax tickets required by a Provincial Local Taxation Bureau to participate in the bidding can be responsible for printing digital anti-counterfeiting invoices, and they are required to have web commercial paper printing equipment: 9-color printing must be completed at one time, and 1 set of silk printing unit or 2 sets of embossing flexographic printing units are equipped online, with skip printing, skip number function, flat cutting and rewinding function; And equipped with high-speed digital inkjet printing equipment; It is used to print anti-counterfeiting information, prize cashing information, invoice number and other functions. However, none of the nine enterprises bidding can meet the above requirements, so they need to increase the software and hardware technology and equipment required for printing the invoice. There are similar situations in other regions, which shows that the existing technology and equipment of some domestic commercial paper printing enterprises can not fully meet the requirements of the new tax invoice printing. 2. The development of commercial paper market is uneven. In areas with lagging economic development, commercial paper has few types of applications, and paper bills are more than special bills, single bills are more than computer invoices, and ordinary paper bills are more than carbon free carbon paper bills. Carbon carbon paper tickets are still popular. From the perspective of the types of business undertaken by commercial paper printing enterprises in such regions, they are mainly financial, tax and bank bills, as well as bills in posts and telecommunications, aviation, hotels and other fields. At the same time, it also greatly promoted the development of bill printing. In large and medium-sized cities with relatively developed economies, due to the needs of service and communication, the commercial paper market is widely used, with many types, a wide range of coverage, and a relatively large number, including postal express mail (EMS) stickers, passbooks, cheques, air tickets, bank receipts, hotel accommodation bills, and taxi special invoices. In such areas, special bills, computer bills and carbon free carbon copy bills are widely used. Especially with the deepening of the construction of the gold card project, the use of various card bases (logic encryption card, high-capacity intelligent CPU card, contactless IC card, composite card, ID card, etc.) in large and medium-sized cities has also been booming. In particular, integrated circuit IC card, because of its large amount of information storage, good security and confidentiality, simple and fast card reading and other advantages, electronic measurement can easily and accurately realize experiments under various test conditions. It has been used in telecommunications, finance, commerce, transportation, social security, medical and health care, sports, taxation, public security, customs, industry and commerce, electric power Organization code and urban public utilities management are widely used in many fields. 3. The market share of commercial paper printing equipment at home and abroad is uneven. At present, the market share of original imported commercial paper printing equipment is nearly 50%, joint venture production is nearly 50%, and the market share of domestic equipment is low. Generally speaking, the proportion of advanced equipment is small, and there are few enterprises in the industry with Bill rotary machines, which can not meet the needs of the current market for bill printing. For example, China has more than 600 computer bill production lines, which is far from meeting the needs of domestic development. 4. At present, the general bill printing market tends to be saturated, and the market competition will be more intense. With the development of market economy, all kinds of securities, banking or finance, insurance, social security and other departments have valuable documents, lotteries, lotteries, tickets, train and ship tickets and a considerable number of valuable securities, including ticket printing and anti-counterfeiting. Through years of practice, We roughly divide the application of new anti-counterfeiting technology in bill printing into the following categories: · anti counterfeiting holographic logo positioning hot stamping technology. The technical difficulty of positioning hot stamping is very high, which requires printing manufacturers to have precision positioning hot stamping equipment; All general holographic anti-counterfeiting technologies can be used on hot stamping labels, such as pixel holography, true color, synthetic encryption, lithography, photochemical relief and other technologies, which can play an excellent anti-counterfeiting effect· Anti counterfeiting technology for micro text printing. The anti-counterfeiting technology of micro text printing is to use micro text or letters to replace simple outlines or lines. For example, there is a light gray thick line at the lower part of the receipt of "civil aviation airport management and construction fee". When you observe it under a magnifying glass, you can see the words in miniature. In commercial paper printing, the microfilm is usually offset printed and completed by a group of offset printing units of the commercial paper printing machine· Rainbow printing anti-counterfeiting technology. Rainbow printing anti-counterfeiting technology is adopted. According to the requirements of commercial paper printing, it can print multiple colors at one time, and the intermediate color transition is soft. The rainbow printing effect is difficult to achieve with the method of multi-color overprint, and it is difficult to see the exact position of the colored partitions in the ink bucket on the commercial paper. Even if the counterfeiter imitates the rainbow printing method, it is difficult to determine the partition spacing, which increases the difficulty of counterfeiting. If this technology is used in large-area shading dagger, its anti-counterfeiting effect will be more obvious· Special anti-counterfeiting printing technology for bills. It has the characteristics of anti-counterfeiting, anti-counterfeiting and easy identification. The special anti-counterfeiting printing technology of bills realizes the close combination of coating and printing process, so that there is printing in coating and coating in printing, and no single technology can be completed. This technology is applicable to the printing of three or more bills. Color changing coating is carried out in the printing process, and printing is realized in the coating process, so that the printed invoice has a very strict coupling. Without any copy, the bill that meets the requirements will not be issued, which can effectively curb the false opening of invoices. In order to prevent users from issuing bills alone or falsely, the color of the invoice sheet is different after the first copy of the triplicate bill is copied in the customer name and the parts of the column of the amount in words, such as one hundred thousand, ten thousand, thousand, hundred, etc; At the same time, the customer name and capital amount columns on the back of the second copy have also been processed, so that the color of one third of the words in the copied third copy is different from other parts. At present, this technology is widely used in national tax, finance, post and telecommunications, transportation, commercial retail, hotels, catering services, administration, customs and other industries and departments. If it can be further expanded, it will create more economic and social benefits for the society and the country· Printing carrier anti-counterfeiting technology and product application. The materials used in the printing carrier can be designed with anti-counterfeiting technology. The bill printing is mainly made of various papers. The paper application can be divided into active anti-counterfeiting, such as watermark paper and all kinds of trace paper; Passive anti-counterfeiting, such as anti copy paper, or anti copy design, anti copy technology is currently widely used in China. Watermark paper accounts for the vast majority of printing anti-counterfeiting paper. Most users we contact use different watermark paper. At present, the application and development of watermark paper is relatively fast, and it meets the conditions required by color printing. At present, the paper making process adopts full neutral. The proportion of paper making increases rapidly, and the storage cycle of paper is long. At the same time, watermark paper can design different colors and technical properties according to the needs of customers, Strengthened the comprehensive anti-counterfeiting ability after introducing high-quality aluminum water from Weiqiao entrepreneurial group. In the market application, 35 ~ 100g/m2 products are used the most, but there is still a certain gap between domestic watermark paper and international advanced products in watermark clarity and paper surface printing coordination, which also limits the application scope of some watermark paper. Trace paper is also an anti-counterfeiting technology proposed in the design idea of watermark paper. Trace mainly refers to the anti-counterfeiting technology that can add materials into the papermaking process and detect traces in the application of finished products, but the added traces must be acceptable in the papermaking process and smoothly identified in the application. The basic principle and application of safety thread paper and other materials are the same. When processing and using anti-counterfeiting pulp, we should also pay attention to some government management links, and some currency anti-counterfeiting technologies should follow the regulations of relevant national departments· Anti counterfeiting technology of printing materials. The anti-counterfeiting technology using printing materials and new processes plays a very important role in the printing process. All kinds of fluorescent inks we have come into contact with have been widely used in China since the early 1990s, and production enterprises have flocked to them, and have indeed achieved a certain anti-counterfeiting effect. Then the application of a π new fluorescent material in currency has promoted the development of anti-counterfeiting printing materials, and the application of ultraviolet light, infrared light, photochromic materials and many other new materials, so that anti-counterfeiting inks and other materials continue to play their anti-counterfeiting functions. With the extensive development of printing consumables, the scientific and technological progress of UV process and many chemical materials, including the development of nano materials, the application of non combustible inorganic materials such as inks will melt in the future, and the anti-counterfeiting materials on consumables will also have relatively large development space, but the main links still need two guarantees, namely, the flexibility of application and the convenience of detection· Application of anti-counterfeiting technology in printing plate making design. Shading anti-counterfeiting is a kind of anti-counterfeiting printing technology with the lowest cost and better anti-counterfeiting effect. The main characteristics of shading anti-counterfeiting are: the full use of lines for anti-counterfeiting can produce rich changes. The anti-counterfeiting design is completed in the process of plate making and realized in printing. According to the principles of optics, spectrum technology, printing technology and other technologies, shading anti-counterfeiting software can also be used to realize various anti-counterfeiting applications such as refraction, latent image and so on. Shading or other anti-counterfeiting elements will not affect the overall design style of the printed matter, because anti-counterfeiting elements such as tuanfua, latent image and microfilm are generally applied locally, which will not affect the overall design style. Generally, the color of shading printing is relatively light, which will not affect the aesthetic effect. The color depth can be set by considering the difference between the human eye and the scanner in the application of optics for color resolution, so that the scanner can't scan out, but the human eye can distinguish. Effects such as relief, refraction, lace, etc. add a new design element to designers. Cooperating with traditional design can provide better design ideas, play a beautiful, eye-catching, easy to understand, and highlight the anti-counterfeiting effect. Common anti-counterfeiting shading elements in printing include: Tuan Hua, curve relief, image relief, lace, latent image, microfilm, shading, variable lineweight, curve analog image, refraction, graphic filtering, etc. Security shading anti-counterfeiting can be understood as two aspects: ① prevention
