Nowadays, counterfeit and shoddy products are popular, A goods can be seen everywhere, and at the same time damage to consumers 'economic interests, they also harm consumers' health. Therefore, in order to protect the corporate brand, protect the market, and protect the legitimate rights and interests of consumers, many companies began to take preventive technical measures, collectively known as anti-counterfeiting technology. Among them, the barcode and ink are mainly related to the packaging and printing industry.
A brief history of anti-counterfeiting technology
After more than 1,000 years of development (from the concept of anti-counterfeiting in China), the anti-counterfeiting products on the market are divided into four generations in terms of technical characteristics and functional evolution:
The first generation of products: products represented by laser anti-counterfeiting, consumers do not have the ability to identify the authenticity of the label, and the label is also easy to forge. In the absence of comparability, 60% of the counterfeit and 100% authentic are difficult to confirm ; The second is the temperature change label, although consumers are easy to identify but also easy to forge. At the same time, nuclear track anti-counterfeiting has also evolved.
The second generation of products: Inquiry digital anti-counterfeiting labels. Consumers can check the authenticity of digital labels via telephone, SMS, or the Internet. However, because the anti-counterfeiting digital is only printed on the surface of paper, it is easy to be forged.
The third generation of products: texture anti-counterfeiting labels, texture anti-counterfeiting is a kind of anti-counterfeiting technology in which the inherent zebra mark of the packaging material is used as an anti-counterfeiting identification mark. Natural markings are always very different, such as fingerprints, wood grains, stone grains, zebra grains, ice grains, dry cracked ground and other textures are random and unique, and it is impossible for two to be exactly the same. Using this principle, the packaging material with clear texture is selected to make anti-counterfeiting labels, and the markings of each label material are photographed, numbered, filed, and stored in the anti-counterfeiting database. Consumers can inquire files through the Internet, fax, and telephone to identify the authenticity. Random principle increases the difficulty of counterfeiting.
The fourth generation of products: security line anti-counterfeiting paper technology and its application products, including various types of product anti-counterfeiting instructions and certificates, anti-counterfeiting bottle stickers, anti-counterfeiting labels, etc. Consumers can easily identify the authenticity by identifying whether the security thread is embedded in the paper. This kind of anti-counterfeiting technology product has a very high imitation threshold, and cannot be forged by printing. It is really easy to identify and difficult to forge. Therefore, it is the most effective anti-counterfeiting technology product for a long period of time at present and in the future.
Fifth-generation products: texture anti-counterfeiting, security thread anti-counterfeiting paper technology moved to the Internet technology, based on the random principle of texture anti-counterfeiting or security thread anti-counterfeiting, for the new modern communication technologies such as smart phones, using two-dimensional codes as identification , So that consumers can directly use the mobile phone to scan, they can get the corresponding information of anti-counterfeiting products, thereby reducing the difficulty of inquiry and identification of consumers. It is extremely difficult to copy, and the anti-counterfeiting effect with a glance identification will soon become the mainstream anti-counterfeiting method, and will become the most effective anti-counterfeiting technical solution in a long period of time in the future.
Application of ink printing in anti-counterfeiting technology
We are now in the fifth generation development stage. Through this development period, we can see that ink and printing methods have always played an important role in it.
There are many varieties of UV screen printing decorative ink, single performance, some use trouble, low production capacity. For example, the silk screen imitation metal etching ink can only be used to print patterns with a sand surface effect. The hemp is generated by the particles in the ink, which is difficult to distribute evenly and has poor repeatability. In addition, there are many kinds of inks such as coarse, medium and fine, and the effects of various prints are different. The UV screen printing wrinkle ink needs to use low-pressure mercury lamp first, and then use the medium-pressure mercury lamp for secondary irradiation and curing to produce wrinkles. The irradiation conditions change slightly, and the patterns of wrinkles produced are obviously different. UV screen printing ice flower nectar needs high-power UV lamp to irradiate for a long time to produce ice flower pattern. It consumes a lot of energy, it will burn the substrate, the production capacity is low, and the scrap rate is very high. use.
Another major disadvantage of screen printing is the poor consistency of printing. The main reason for poor printing consistency is that the basic elements such as dots and lines of decorative patterns printed by the screen method are random and disorderly arranged, which depends on the mechanism of the process. Another reason is that the long service life of the current screen version is 40,000 to 50,000 sheets, and the short one can only print 10,000 sheets. During use, the screen gradually relaxes and deforms, and the photoresist gradually falls off, so that the printing quality gradually declines. Some products, such as Wuliangol, are very large in quantity. When printing, dozens of screen machines are printed together. The difference in plate-making, the shape of the blade, the size of the effort, and the distance between the screen and the paper all affect the printing results. For this reason, even if the same product, the same ink, and the same factory printing are used, the effect of the resulting printed matter is also different, and the difference between them can be observed with the naked eye, which provides convenience for some counterfeiters. This determines that the decorative patterns printed by the silk screen method have only decorative functions, but no anti-counterfeiting functions.
Moulded laser rainbow holographic technology is used in tobacco and alcohol packaging. Rainbow hologram can display colorful stereoscopic picture, the image is floating and floating, the color is infinitely changeable. Observing from different angles can get different pictures, has a perfect three-dimensional sense, and has an excellent decorative effect on the packaging. The anti-counterfeiting function is supposed to be good. However, driven by economic interests, many units that can prepare laser holographic stencils have undertaken business externally. Moreover, if the pattern of the holographic rainbow is not specially processed, it can be copied by a very simple method. Although the quality of the copied image is reduced, the copy of the holographic rainbow commissioned is also different from the real one. From an angle of view, the color is infinitely variable. As long as these images are similar in shape, it is difficult to distinguish the authenticity from the naked eye. For this reason, its anti-counterfeiting function has been significantly reduced.
Another important means of high-end packaging for anti-counterfeiting is anti-counterfeiting ink. These inks have special functions that general inks do not have, such as thermal discoloration, pressure-sensitive discoloration, photosensitive discoloration, moisture-sensitive discoloration, ultraviolet fluorescence, etc. In packaging, thermochromic discoloration is used the most. Corresponding color-changing pigments are added to these inks. These color-changing pigments have specific properties. For example, above a certain temperature, the ink can change from one color to another. However, in China, most of the pigments can be purchased except for a few special anti-counterfeiting pigments, such as currency and securities printing, and restricted sales. And there are many advertisements of anti-counterfeit color-changing ink, you can buy it, and others can also buy it, which opens a convenient door for counterfeiters.
Although each thermal anti-counterfeiting ink has a specific color change temperature, the color before and after thermal change is also constant, but consumers often use a lighter to bake the graphics printed by the color change ink to identify the authenticity, as long as the baking occurs Color change is fine. I don't care about the slight difference in color. Of course, it is impossible to measure the color change temperature. It often happens that a color-changing logo is printed on a famous cigarette package, the original purpose of which is anti-counterfeiting. But the fake seller took out the lighter in a decent way and baked it at the discoloration mark of the fake, and one color changed to another color, making you have to believe that it is genuine.
Conclusion
In order to improve the anti-counterfeiting performance, manufacturers often combine many advanced printing processes. What laser hologram rainbow, thermal discoloration, frosting, wrinkles, ice flowers, hot stamping, hot rainbow, etc. are used. It seems that the more complicated the process, the harder others Imitation.
This is not the case, because the above processes are all screen printing or hot stamping. It is difficult to register during printing, and each process will produce printing deviations. For this reason, the more complicated the process, the more processing steps, not only the higher the printing cost, but also the greater the deviation. So that even the same batch of printed matter, there are differences in almost every sheet, and the equipment of counterfeiters is becoming more and more advanced, the level of counterfeiting is getting higher and higher, and finally the imitation products are mixed in, and even they can't tell the authenticity from themselves, consumers How can it be recognized? Therefore, the ideal anti-counterfeiting measures and measures should pay attention to avoid using too many processes in the process.
