XIII. Stealth security ink:

The anti-counterfeit principle is to add invisible marks such as Isotag, Coircode, etc. to the general ink. Its anti-counterfeiting feature is due to the fact that these marks are invisible, and only when professionals and certain instruments and light of a specific wavelength irradiate the specific marks appear, and thus the authenticity thereof can be identified. Its technical content is higher and its anti-counterfeiting performance is better.

XIV. Intelligent Machine Read Security Ink:

The principle of anti-counterfeiting is to use the variability of intelligent anti-counterfeit materials, that is, the anti-counterfeiting material consists of a variety of variable chemical substances, including the nature, type, quantity, content, and existing forms of the characteristic compounds to constitute the particularity and individuality of the security materials. Then, according to these special characteristics and the production of anti-counterfeiting materials and manufactured detection equipment (can be processed by the calculator, the results obtained, the authenticity of the test) to achieve anti-counterfeiting purposes. Its security features include: (1) Uniqueness and complexity. The technology used in the technology has many components, many production equipments, large investment, and complicated processing technology. (2) High technology content. The technology spans multiple disciplines and integrates multidisciplinary science and technology. (3) Intuitive and quick. The results can be seen directly from the calculator screen in 5 to 30 seconds. (4) Dedicated. Due to the use of calculator identification, the variability is extremely strong. Each authentication terminal has anti-counterfeit products and machine encryption. Only when it knows the identity of the seized mark or the seal code at the same time can it be identified with a dedicated detection instrument.

15. Multifunctional or integrated security inks:

Anti-counterfeit principle is to add other anti-counterfeiting technology in the general anti-counterfeit ink, so as to achieve multiple anti-counterfeiting functions. For example, a laser holographic logo combined with a fluorescent encryption security ink. Its anti-counterfeiting features, such as laser hologram identification combined with fluorescence encryption anti-counterfeiting ink, add new anti-counterfeiting measures to perform secondary encryption without increasing the integrity of the laser holographic identity, thereby improving its anti-counterfeiting function. Currently, a secondary encryption comprehensive anti-counterfeiting technology for laser hologram identification has been adopted on the market, ie, a special fluorescent material that can be detected through a certain process after being added to the laser hologram logo, is invisible to the naked eye under sunlight, and displays special features in the detection of special instruments. Colored fluorescent graphic. The technology has the characteristics of friction resistance, heat resistance, convenient and accurate detection, and strong anti-counterfeiting, and the production cost is less increased.

16. Light Variable Ink (OVI):

The principle of anti-counterfeiting is to add special materials to the ink, which will cause discoloration of the seal under different lighting angles. This is a kind of anti-counterfeiting ink with high technological content. Due to the complicated raw material production process, high technical difficulty, and large investment in equipment, the cost is relatively high and it is very difficult to prevent it. This kind of ink is mainly used for the printing of important documents such as banknotes, evidence, identity cards, passports, and securities. The inks that can only be adapted to the printing are gravure printing and screen printing. However, at present, there is also a dioptric ink which also has a refractive color effect. Due to its simple processing of raw materials, although the color change effect is far less than OVI, it can also play a security effect, and the cost is relatively low.

Seventeen nano ink:

Nanomaterials and nanotechnology are emerging high-tech products. Now they have developed rapidly. They have begun to penetrate into various fields and have successfully obtained a lot of high-performance and special-performance materials. This is a new material in the history of material development. Milestones. Nanometers are a unit of length, meaning that the material itself is in an ultra-small, ultra-fine state. Based on the various properties of nanomaterials, applying it to the ink system will bring a huge boost to the ink industry. Actually, there are many ways to obtain nanomaterials, such as high-temperature sintering (such as sintering of carbon nanotubes), precipitation, high-temperature water dissolution, chemical vapor condensation, or modern plasma energy polymerization. By means of the above methods, various components in the ink, such as resins, pigments, fillers, etc., can be made into nanoscale raw materials. In this way, because of their high degree of fineness, they have good flow and lubricity, they can achieve better dispersion, suspension, and stability. The amount of pigment used is less, but the hiding power is high, the gloss is good, the resin particle size is fine, and the film formation is continuous, uniform and smooth. The layer is thin, but the image is clear. If used in a UV ink, it may result in a faster curing rate while eliminating shrinkage wrinkling of the film due to the fine and uniform dispersion of the filler.

In the case of glass-ceramic inks, if the inorganic materials constitute nano-scale fineness, it will save a lot of raw materials and print more refined and more beautiful higher quality patterns. In the pigment industry, the ink manufacturing industry has brought about a tremendous change. It no longer relies on chemical pigments but instead selects the appropriate volume of nanoparticles to present different colors. Because some substances in the nano-scale, different particle sizes, colors are different, or different substances, different colors, such as Ti02, Si02 in the nanoparticles are white, Cr203 is green, Fe203 is brown. There are also inorganic nanomaterials such as nano-A1203 with good fluidity, if added to the ink can greatly improve the wear resistance of the ink film. Nano-scale carbon ink is conductive, has a good shielding effect on static electricity, to prevent electric signals from being disturbed by external static electricity. If it is added to ink, it can be made into conductive ink, such as large-capacity integrated circuits, modern contact panel switches, etc. . In addition, in conductive inks, if Ag is made into nano-scale instead of micro-sized Ag, 50% of Ag powder can be saved. This conductive ink can be directly printed on ceramic and metal. The film is thin and even and smooth. . If the Cu, Ni material made of 0.1 ~ 1μm ultrafine particles, it can replace the palladium and silver and other metals conductive. Therefore, the combination of nanotechnology and anti-counterfeiting technology will open up another broad field of security ink.

In recent years, with the continuous development of anti-counterfeit printing, as well as the research and development of anti-counterfeiting technology, the production and application of anti-counterfeiting technology products have also been rapidly developed. Anti-counterfeit ink is one of the most important technical branches in anti-counterfeiting technology. It covers many subjects such as optics, chemistry, electromagnetism, calculator technology, spectroscopy, printing technology, graphic digital technology, packaging technology, etc. It is A crossed edge subject. Among them, chemical anti-counterfeiting materials and technologies are the basic technologies of anti-counterfeit inks, occupying a very important position in research and application, and having irreplaceable functions in the field of anti-counterfeiting.

According to the characteristics of anti-counterfeiting technology products, namely: technical reliability, product exclusiveness, simplicity of identification, uniqueness of identification, anti-counterfeit timeliness, cost usability, etc., it is therefore required that anti-counterfeit ink technology should be the current ticket security and its trademark packaging anti-counterfeiting field. The highly practical technology can not only meet the requirements of the public's first-line anti-counterfeiting identification, but also meet the requirements for the identification and supervision of the second- and third-line senior experts and management departments. Now, with the rapid development of Chinese anti-counterfeit ink technology, some technologies have caught up with and surpassed the international advanced level, but due to management omissions, it has also led to a reduction in the security of some anti-counterfeiting inks.

Packaging, trademark anti-counterfeiting is the use of a variety of anti-counterfeiting means the most important aspect, and its core is the use of anti-counterfeiting ink printing, so in the development of a series of anti-counterfeit products standards, security ink standards are essential. In 1995, under the leadership of the State Bureau of Technical Supervision, the National Anti-counterfeiting Standardization Technical Committee was established, and the “Measures for the Management of Anti-counterfeiting Technology Products” was formulated to strengthen the management of anti-counterfeiting technology products to prevent and combat counterfeit 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 approach is "Technical Standards for Anti-Counterfeit Products." In 1997, some standards for anti-counterfeiting ink were issued, which played a very important role in solving the disorderly industry competition, regulating the anti-counterfeit market, promoting technological advancement and technological innovation, and accelerating the pace of anti-counterfeiting technology development.

The future development of anti-counterfeiting inks will not only satisfy the needs of general public identification, but also satisfy the need of government departments to supervise arbitration. Through the special performance of anti-counterfeiting information, it will accurately determine the authenticity. This is also a new concept of modern tickets and other anti-counterfeiting. It is the road to the development of anti-counterfeit technologies.

In the production of anti-counterfeiting inks, we must continue to develop new materials and develop new technologies. Such as the use of functional polymers, biological genes, optical, electrical, magnetic, thermal, laser holographic and other materials and science and technology, using new technology to create more high-grade anti-counterfeiting ink. In addition, in terms of anti-counterfeiting measures, in view of the fact that the anti-counterfeiting performance of a single anti-counterfeiting technology and means has been continuously declining, it is necessary to strengthen the development and production of comprehensive anti-counterfeiting and multi-functional anti-counterfeit technologies in order to achieve more high-grade anti-counterfeiting purposes. For example, the following anti-counterfeiting technology can be used to produce multifunctional security inks.

(1) Daylight anti-counterfeiting anti-counterfeiting technology: Daylight anti-counterfeit anti-counterfeiting technology is a more advanced first-line anti-counterfeiting technology, it is simple and convenient to identify, you can see the obvious color change effect under sunlight, but also through long-wave ultraviolet light (ie, check money Machine) inspection.

(2) Intelligent spectrum analysis anti-counterfeiting technology: It is a high-tech second-line and three-line anti-counterfeiting technology that combines very special encrypted substances and machine intelligence.

(3) Long-wave and short-wave fluorescent anti-counterfeiting technologies: Long-wave fluorescence anti-counterfeiting technology is the world's advanced anti-counterfeiting technology.

(4) Fixed-temperature thermal anti-counterfeiting technology: organic complexes with specific chemical coloration (for example, 30°C, 40°C, or 50°C) are used, and the molecular structure is complex in design, with many varieties and rich discoloration. For example, From colorless to colorless or one color to another color.

(5) Laser holographic anti-counterfeiting technology: It uses the basic laws of scattering, interference, reflection, transmission, absorption and diffraction generated by the interaction of light and matter to obtain a special visual effect. At present, the main technical means are a multilayer dielectric film structure using a thin-film interference effect, a grating structure, and various types of optical holography techniques that utilize information optics concepts. With the appearance and maturity of various processes, especially the molding process, and the improvement of other advanced technologies, the cost and anti-counterfeit performance of mass production have been greatly improved, thus becoming the preferred technology for the current packaging and other areas of anti-counterfeiting.

All these anti-counterfeiting technologies can be combined with anti-counterfeiting inks in one or more ways to produce anti-counterfeit inks with higher anti-counterfeiting performance and lower cost, so as to serve higher and broader anti-counterfeiting products.

In short, the battle between anti-counterfeiting and counterfeiting has ceased without interruption. “One foot tall and one hundred feet high,” because today's monopoly of anti-counterfeit materials and technology has declined, anti-counterfeiting materials such as security ink, paper, etc. Machinery and equipment are not well controlled. Most people can buy it everywhere. This intensifies the proliferation of counterfeiting. Today, in the market, from counterfeit currency, fake bills, to counterfeit goods, everywhere, to the people's lives and society. The stability of the economic order has had a very bad effect. Therefore, the research and development of anti-counterfeiting technology is even more imperative. From the development trend of international and domestic printing anti-counterfeiting technology, we use various disciplines of technology, a variety of superior technologies, multi-disciplinary joint use, and constantly develop new anti-counterfeiting materials, introduce new anti-counterfeit technologies, develop integrated anti-counterfeiting technologies, and adopt comprehensive anti-counterfeiting technologies. The road is an inevitable trend in the development of anti-counterfeiting technology. In addition, knowledgeable people also called for the strengthening of management of anti-counterfeit materials, technologies, and equipment, so that they truly become exclusive technologies and materials. In this way, we can better prevent the proliferation of counterfeit products.
