Method for identifying anti-counterfeiting labels when dripping disappears

by:LG Printing     2021-04-07
Anti-counterfeiting products not only require high anti-counterfeiting technology content, making it difficult for counterfeiters to imitate, but also easy to be distinguished by consumers. No matter how good an anti-counterfeiting product is, it is difficult for consumers to identify the authenticity or it is useless, but the anti-counterfeiting label for the disappearance of drips has these conditions. It is not only high in anti-counterfeiting technology, but also easy to identify. It can be distinguished by just passing through a drop of water. Pseudo. So, what is the principle of the disappearance of dripping anti-counterfeiting label?

  一. How to identify the disappearance of drips

  1. Consumer identification:

   Drop a drop of water on the label, the text or the picture will disappear, and the authenticity can be distinguished. The principle is to achieve the effect of discoloration through the interaction of water and ink. There are mainly water-changing inks and moisture-sensitive inks. When water-changing inks are white, they become transparent when they meet with water, and they become white when they are dry. Moisture-sensitive inks are divided into two types: reversible and irreversible. One is that the color becomes colorless after being exposed to water, and the original color is restored after the water dries, which is reversible. The other is that the original picture will become blurred when it encounters water, and it will not be restored to its original state after the water is dry. Using this anti-counterfeiting technology does not have to worry about the label being reused, and it is mostly used to check whether batteries and electrical appliances are in contact with water.

  2. Use the micro-holes formed by the ion and nanometers in the pattern for anti-counterfeiting, and observe the anti-counterfeiting mark of the dripping disappearing technology made of nano-materials with a thickness of more than ten meters under the academic microscope. The logo pattern part is composed of a large number of micron-sized pores. The pore diameter and pore density of these micropores can be changed according to the requirements of users, that is, different manufacturers can set their own pore diameter and pore density, the pore type of the micropores is cylindrical, and the pore distribution is random. The anti-counterfeiting signs produced by China Ion Accelerator are distributed randomly at a certain discrete angle in each cylindrical channel. The imitation of the latter anti-counterfeiting signs is almost impossible. The above method can also be used to analyze the patterns with pictures and analyzers. Part of the pore size and pore density are identified.

  3. Use the permeability of micro-channels for anti-counterfeiting identification. Use water, wine and other liquids to apply the dripping vanishing technology anti-counterfeiting logo pattern. As the holes are filled with liquid, the optical structure of the surface layer changes and the pattern becomes shallower and disappears. For example, when a color pattern is printed on the back of the pattern, the color pattern on the back of the pattern changes It is more obvious that once the liquid evaporates, the pattern returns to its original shape. The pattern disappears to the recovery process, which is obvious, about 30 seconds to 60 seconds. Primary products that have not undergone nano-processing disappear slowly and cannot be combined with other anti-counterfeiting technologies.

  4. Use a high-power magnifying glass for anti-counterfeiting identification. Use a 120-fold magnifying glass to carefully observe the pattern part of the anti-counterfeiting mark, and you can see that the pattern is composed of irregular dots. Anti-counterfeiting Co., Ltd.'s anti-counterfeiting printing is a simple and easy-to-operate nano-level material anti-counterfeiting in anti-counterfeiting detection. It only needs a drop of water to smear the label during identification. It is an advanced anti-counterfeiting technology in China.

The disappearance of    dripping water is widely used on all kinds of anti-counterfeiting labels as a new anti-counterfeiting technology because of its easy identification and difficult to forge characteristics. The anti-counterfeiting printing of anti-counterfeiting is simple and easy to operate in anti-counterfeiting detection. It only needs a drop of water to smear the label during identification. It is an advanced anti-counterfeiting technology in China. The manufacture of anti-counterfeiting labels with dripping water requires special printing ink and plate-making process. Because the outer surface layer cannot be coated properly, the ink and water must be adequately reacted to reach the effect. It is based on the dripping filter technology, which is the part of the area that will be reacted. The semi-transparent micropores are formed and equipped with special ink, so that they can fully react with water and achieve invisible effects. There are many ways to identify drip anti-counterfeiting labels, which are simple and convenient, so they are widely used.
