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 technical branches in anti-counterfeiting technology. It involves many subject areas, such as optics, chemistry, electromagnetics, calculator technology, spectroscopy technology, printing technology, graphic digital technology, packaging technology, etc. A cross-disciplinary subject. Among them, chemical anti-counterfeiting materials and technologies are the basic technologies of anti-counterfeiting inks, occupying a very important position in research and application, and have an irreplaceable role in other technologies in the field of anti-counterfeiting.

According to the characteristics of anti-counterfeiting technology products, namely: technical reliability, product exclusivity, simple identification, unique identification, anti-counterfeiting timeliness, cost availability, etc., therefore, anti-counterfeiting ink technology should be the current field of ticket anti-counterfeiting and its trademark packaging The highly practical technology can not only meet the requirements of the public's first-line anti-counterfeiting identification, but also meet the identification and supervision requirements of the second- and third-line senior experts and management departments. At present, the technology of counterfeit ink in China's defense industry is developing rapidly, and some technologies have caught up with and surpassed the international advanced level, but due to omissions in management, it has also led to a reduction in the security of some anti-counterfeit inks.

Packaging and trademark anti-counterfeiting are the most important aspects of various anti-counterfeiting methods. Its core is the use of anti-counterfeiting inks in printing. Therefore, in formulating a series of anti-counterfeiting product standards, the standard of anti-counterfeiting inks is essential. In 1995, under the leadership of the State Technical Supervision Bureau, the National Anti-counterfeiting Standardization Technical Committee was established, and the "Anti-counterfeiting Technical Product Management Measures" was formulated to strengthen the management of anti-counterfeiting technical products to prevent and combat counterfeiting and illegal activities, maintain market economic order, and protect The legitimate rights and interests of producers and consumers of products. One of the important technical basis for the implementation of this management method is "technical standards for anti-counterfeit products". In 1997, some standards for anti-counterfeiting inks were promulgated, which played a very important role in solving the disorderly competition in the industry, standardizing the anti-counterfeiting market, promoting enterprise technological progress and technological innovation, and accelerating the pace of anti-counterfeiting technology development.

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

In the production of anti-counterfeiting ink, we must continuously develop new materials and develop new processes. Such as the use of functional polymers, biological genes, light, electricity, magnetism, heat, laser holography and other materials and scientific technology, the use of new processes to manufacture higher-grade anti-counterfeiting ink. In addition, in terms of anti-counterfeiting measures, in view of the fact that the anti-counterfeiting performance of single anti-counterfeiting technologies and means has been declining, it is necessary to strengthen the development and production of comprehensive anti-counterfeiting and multi-functional anti-counterfeiting technologies in order to achieve higher-grade anti-counterfeiting purposes. For example, the following anti-counterfeiting technology can be used to produce a multi-functional anti-counterfeiting ink.

(1) Anti-counterfeiting technology of sunlight discoloration: Anti-counterfeiting technology of solar discoloration is the most advanced first-line anti-counterfeiting technology at present. Its identification method is simple, and the obvious color-changing effect can be seen under the sunlight. Machine) inspection.

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

(3) Long-wave and short-wave fluorescent anti-counterfeiting technology: Long-wave fluorescent anti-counterfeiting technology is the advanced anti-counterfeiting technology currently used in the world

(4) Fixed-temperature thermal anti-counterfeiting technology: using specially chemically synthesized organic complexes with specific color change temperature (such as 30 ℃, 40 ℃ or 50 ℃), the molecular structure design is complex, there are many varieties, and the color change is rich. For example, From colored to colorless or from one color to another.

(5) Laser holographic anti-counterfeiting technology: use the basic laws of scattering, interference, reflection, transmission, absorption, diffraction, etc. generated when light interacts with substances to obtain a special visual effect. At present, the main technical means are multi-layer dielectric film structures using thin-film interference effects, grating structures, and various types of optical holography techniques using information optics concepts. 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 its mass production have been greatly improved, and it has become the preferred technology in packaging and other anti-counterfeiting fields.

All of the above anti-counterfeiting technologies can be combined with one or more anti-counterfeiting inks to produce anti-counterfeiting inks with higher anti-counterfeiting performance and lower cost, so as to serve higher and wider anti-counterfeiting products.

In a word, the battle between anti-counterfeiting and counterfeiting has never stopped. "The road is one foot high, the magic is one foot high." As the exclusiveness of anti-counterfeiting materials and technologies has declined, anti-counterfeiting materials such as anti-counterfeiting ink and paper , Machinery, equipment, etc. are not well controlled, and ordinary people can buy it everywhere, which has exacerbated the proliferation of counterfeiting. Nowadays, in the market, from counterfeit currency, counterfeit bills to counterfeit goods, everywhere exists, giving people ’s lives and society The stability of the economic order has a very bad effect. Therefore, the research and development of anti-counterfeiting technology is even more imperative. From the perspective of the development trend of international and domestic printing anti-counterfeiting technology, the use of technologies in various disciplines, a variety of superior technologies, and multi-disciplinary joint use, continue to develop new anti-counterfeiting materials, introduce new anti-counterfeiting technologies, and develop to comprehensive anti-counterfeiting technologies, taking comprehensive anti-counterfeiting The road is an inevitable trend in the development of anti-counterfeiting technology. In addition, people of insight also called for truly strengthening management of anti-counterfeiting materials and technologies, equipment, etc., to make them truly exclusive technologies and materials. In this way, we can better prevent the proliferation of counterfeit products.
