Macao Dragon Banknote Anti-counterfeiting

MOP 10 the Year of the Loong New Year's Coin is the most advanced and sophisticated anti-counterfeiting technology in the same denomination MOP. Next, the author analyzes the Year of the Loong Lunar New Year coins one by one from several anti-counterfeiting technologies, such as fixed watermark technology, spark technology, SD gravure printing technology, offset printing technology, gravure touch line, two-color special-shaped double numbers, gravure microfilm and so on. First, fix the lotus watermark image. Click to open it in a new window to see the watermark. It means formed in the process of papermaking. By changing the density of pulp fiber, the unique pattern is "sandwiched" in the paper, not on the surface of the paper. When you see the light and dark texture, you can clearly see people, portraits or words. It is made of paper in the production process. It is usually used for anti-counterfeiting of various banknotes and valuable securities, and in recent years it has also been used for anti-counterfeiting of general commercial documents. According to the position of watermark in paper, watermark can be divided into full-page watermark and fixed watermark. According to the thickness and transparency of watermark, watermark can be divided into black watermark and white watermark (high transparency watermark). This version of MOP is no exception, adopting the internationally popular fixed black watermarking technology. In the left margin of the middle part of the front of the two new Macao banknotes, a clear lotus fixed watermark can be seen under the perspective of light. The fixed watermark has clear lines, natural transition between light and shade and strong stereoscopic effect. Generally, counterfeit banknotes are mostly printed on the surface of paper with light ink, which can not achieve three-dimensional effect. Watermark plays a very important role in anti-counterfeiting work. Second, the glorious light-to-ink (Spark Technology) picture can be opened in a new window to view the glorious light-to-ink, which is actually Spark Technology and translated into Chinese. Its characteristic is that while changing the angle and line of sight of paper money, the text or graphics printed by this technology always run through a gorgeous light and roll with it. This technology is one of the anti-counterfeiting measures gradually used in paper money in recent years. This technology was adopted in the Olympic commemorative banknotes issued by China in 2008. This technology was also used in the commemorative voucher of "70th Anniversary of Shanghai Banknote Printing Factory" issued by China Banknote Printing and Minting Corporation in 20 1 1, and it was widely used in Macao and Hong Kong dollars. For example, bank of China's 2008 page 100 and above banknotes are all used in the 20 10 editions issued by three note-issuing banks in Hong Kong. It can be said that the application of SPARK brilliant dimming ink technology adds luster to the overall aesthetic feeling of paper money. Third, click the anti-counterfeiting picture of the printed pattern to open it in a new window. Printing technology is widely used in the 20 12 version of Macao New Year banknotes. The so-called printing technology is actually to make the graphics and texts on the front and back of the banknote accurately printed together according to the design. After exposure, it will be found that the error of the printing pattern is very small, almost 1 0,000% completely overlapping, and the printing is accurate. In the two versions of New Year pictures, the paper-cut dragon on the front and the paper-cut dragon on the back are completely printed, and the incomplete denomination number "10" on the upper left of the front of the banknote is also completely consistent with another group of incomplete denomination numbers "10" on the back, forming a complete denomination number "10". Contrasting patterns are generally divided into offset printing and SD gravure printing. Offset printing is widely used in banknote anti-counterfeiting. SD gravure printing technology is a new generation of anti-counterfeiting technology with independent research and development intellectual property rights in China. At present, it has been seen in the "Qi Baishi SD gravure printing" in the book "RMB anti-counterfeiting technology and authenticity identification". 4. Gravure processing line image click to open it in a new window. Gravure printing technology has been widely used in anti-counterfeiting printing, and gravure handle line has been used for banknote anti-counterfeiting in recent years. Through deep gravure printing, paper money has a strong sense of concave and convex, and it is easy to identify counterfeit money by touching it, which is an important anti-counterfeiting measure. This technology was adopted in the fifth set of RMB issued by the People's Bank of China in 2005. This anti-counterfeiting measure was also adopted in the upgraded MOP issued by Bank of China in 2003. Both banks have adopted this technology in this kind of Chinese New Year paper money. At the same time, in the design, they will also find that the concave touch lines on both sides of the banknote are actually the denomination number "10". 5. The picture of two-color shaped double-numbered Chinese character crowns can be opened in a new window to view the 20 12 the Year of the Loong new banknotes. The "Renchen" Chinese character crowns are used as banknotes, arranged in two-color shaped double numbers, one horizontal and one vertical. In the horizontal number, the middle crown character and the first three and a half digits are red, the last three and a half digits are black, and the fourth digit is butted with two colors, which is accurate. At the same time, the number of numbers only increases gradually from the left. The vertical crown number is printed with a single black irregular number, and the two groups of numbers are exactly the same. Two-color number docking technology is a technical challenge for counterfeiters. This technology is not the first time to use this version of banknotes. It has been used in the MOP of the Bank of China in 2003, and this new year's coin of the Atlantic Bank has also applied this technology. 6. Microfilm picture Click to open in a new window to view microfilm, which became popular in the late 1980s. Microfilm includes gravure microfilm and offset microfilm. This anti-counterfeiting measure can prevent copying to a certain extent. At present, most counterfeit banknotes are made by laser scanning, while real banknotes are printed by gravure or offset printing technology because of their small size. Even after high-resolution scanning, printing again will lead to blurred printing and unclear text. So it plays an anti-counterfeiting role. The horizontal pattern of Chinese denomination "MOP Round" on the front of Chinese New Year banknotes is gravure microfilm. The dotted line under the name of the Portuguese bank on the front of the New Year's greeting card of Atlantic Bank is actually a gravure microfilm. If you look under a magnifying glass, you will see clean and coherent words. Seven, the window security line picture Click to open it to view the zodiac New Year notes in a new window. This time, instead of using the previous holographic window security line, a new window security line is adopted. There are four windows on the back of paper money. The denomination number "10" is uniformly printed on the security line. At the same time, changing different angles, the security line color of the window opening part is also very bright, which is completely different from the holographic window opening security line used in the past. The security thread of counterfeit banknotes and the security thread of window opening are mostly printed on the surface of paper with special ink, which produces the effect similar to that of window opening security thread or security thread. In fact, the surface of the banknote is only printed with pictures and texts, and there is no actual security line in the banknote. The difference between real banknotes is that it is also in the paper added by special technology during papermaking. Even unprinted banknotes have security lines for opening windows. Counterfeit money is actually a blank sheet of paper before printing. Therefore, the application of this anti-counterfeiting technology in New Year pictures is also of great significance. Above, we have simply discussed and analyzed several important anti-counterfeiting measures in Macao New Year Zodiac New Year greetings. As a banknote with a face value of only 100 yuan (equivalent to RMB about 8 yuan), it is rare to use such advanced anti-counterfeiting technology in the New Year's vouchers with a total circulation of about 20 million. Advanced anti-counterfeiting technology, exquisite printing level and novel New Year theme are believed to bring us not only the meaning of New Year greetings, but also the charm brought by printing technology.
