In recent years, with the continuous development of anti-counterfeiting printing and the research and development of anti-counterfeiting technology, the production and application of anti-counterfeiting technology products have also developed rapidly. Anti counterfeiting ink is one of the most important branches of anti-counterfeiting technology. It involves many disciplines, such as optics, chemistry, electromagnetism, calculator technology, spectrum technology, printing technology, graphic digital technology, packaging technology, etc. it is an interdisciplinary frontier discipline. Among them, chemical anti-counterfeiting materials and technologies are the basic technologies of anti-counterfeiting inks, which occupy a very important position in research and application, and play an irreplaceable role in the field of anti-counterfeiting

according to the characteristics of anti-counterfeiting technology products, i.e. technical reliability testing machine, aero-engine composite materials, question and answer of aircraft internal composite material factory, product exclusivity, simplicity of identification, uniqueness of identification, anti-counterfeiting timeliness, cost availability, etc., it is required that anti-counterfeiting ink technology should be a very practical technology in the field of ticket anti-counterfeiting and trademark packaging anti-counterfeiting at present, It can not only meet the first-line anti-counterfeiting identification requirements of the public, but also meet the identification and supervision requirements of the second-line and third-line senior experts and management departments. At present, the technology of anti-counterfeiting ink in China has developed rapidly, and some technologies have caught up with and exceeded the international advanced level. However, due to the negligence of management, the safety of some anti-counterfeiting ink has also been reduced

packaging and trademark anti-counterfeiting are the most important aspects of adopting various anti-counterfeiting means. Its core is the use of anti-counterfeiting ink in printing. Therefore, in formulating a series of anti-counterfeiting product standards, the standard of anti-counterfeiting ink is essential. In 1995, under the leadership of the State Bureau of technical supervision, the national anti-counterfeiting Standardization Technical Committee was established, and the "anti-counterfeiting technical product management measures" were formulated to strengthen the management of anti-counterfeiting technical products, prevent and combat counterfeiting and illegal activities, maintain the market economic order, and protect the legitimate rights and interests of producers and consumers of products. One of the important technical bases for implementing this management method is the "technical standards for anti-counterfeiting products". In 1997, some anti-counterfeiting ink standards were issued, which played a very important role in solving the disordered competition in the industry, standardizing the anti-counterfeiting market, promoting the technological progress and technological innovation of enterprises, and accelerating the pace of anti-counterfeiting technology development

the future development direction of anti-counterfeiting ink, its technology can not only meet the needs of general public identification, but also meet the needs of government supervision and arbitration, and accurately judge the authenticity through the special performance of anti-counterfeiting information. This is also a new concept of modern tickets and other anti-counterfeiting, and it is the road for the development of anti-counterfeiting technology

in the production of anti-counterfeiting ink, it is necessary to continuously develop new materials and new processes. Such as using functional polymers, biological genes, optical, electrical, magnetic, thermal, laser holography and other materials and science and technology, and adopting new processes to manufacture higher-grade anti-counterfeiting inks. In addition, in terms of anti-counterfeiting means, in view of the fact that the anti-counterfeiting performance of a single anti-counterfeiting technology and means has been declining, it is necessary to strengthen the development and production of comprehensive anti-counterfeiting and multi-functional anti-counterfeiting technologies to achieve higher-grade anti-counterfeiting purposes. For example, the following anti-counterfeiting technologies can be used to produce multi-functional anti-counterfeiting inks

(1) sunlight discoloration anti-counterfeiting technology: the sunlight discoloration anti-counterfeiting technology is a more advanced front-line anti-counterfeiting technology at present. Its identification method is simple, and obvious discoloration effect can be seen under sunlight, and it can also be tested by long wave ultraviolet light (i.e. banknote detector)

(2) intelligent spectrum analysis anti-counterfeiting technology: it is a high-tech second-line and third-line anti-counterfeiting technology that combines very special encrypted substances with machine intelligent identification

(3) special anti-counterfeiting technology for long wave and short wave fluorescence: long wave fluorescence anti-counterfeiting technology is an advanced anti-counterfeiting technology currently used in the world

(4) constant temperature thermal anti-counterfeiting technology: it adopts specially chemically synthesized organic complexes with specific color changing temperature (such as 30 ℃, 40 ℃ or 50 ℃), with complex molecular structure design, many varieties and rich color changing, for example, it can change from color to colorless or from one color to another

(5) laser holographic anti-counterfeiting technology: the South China branch of the "National Engineering Research Center for engineering plastics" built in Changping Town uses the basic laws of scattering, interference, reflection, transmission, absorption and diffraction generated by the interaction between light and matter to obtain a special visual effect. At present, the main technical means are multilayer dielectric film structure, grating structure and various types of optical holography using the concept of information optics. With the emergence and maturity of various processes, especially the molding process, and the improvement of other advanced technologies, the cost and anti-counterfeiting performance of mass production have been greatly improved, thus becoming the preferred technology in packaging and other anti-counterfeiting fields

the above anti-counterfeiting technologies can be combined with anti-counterfeiting inks in one or more ways to produce anti-counterfeiting inks with higher anti-counterfeiting performance and low cost, so as to serve higher and broader anti-counterfeiting products

in a word, the struggle between anti-counterfeiting and counterfeiting has never stopped. The "one foot higher, one foot higher" magic is. As the monopoly of anti-counterfeiting materials and technologies has declined, anti-counterfeiting materials such as anti-counterfeiting ink, paper, machinery and equipment have not been well controlled, and ordinary people can buy them everywhere. This has exacerbated the proliferation of counterfeiting. Now, there are everywhere in the market, from counterfeit money, fake tickets to counterfeit goods, It will have a very bad impact on people's lives and the stability of social and economic order. Therefore, the research and development of anti-counterfeiting technology is more likely to fully meet the various temperature control indicators specified in the national standards. From the development trend of international and domestic printing anti-counterfeiting technology, it is an inevitable trend for the development of anti-counterfeiting technology to continuously develop new anti-counterfeiting materials, launch new anti-counterfeiting technology, develop towards comprehensive anti-counterfeiting technology and take a comprehensive anti-counterfeiting road by using the technology of various disciplines, a variety of advantageous technologies and the combination of multiple disciplines. In addition, people with knowledge also called for strengthening the management of anti-counterfeiting materials, technologies and equipment, so as to make them truly exclusive technologies and materials. In this way, we can better prevent the proliferation of counterfeit products
