Application of Anti-counterfeiting Technology in Label Printing Industry

In order to increase the value-added considerations of products, or to highlight the uniqueness of the products, anti-counterfeit technologies have become the focus of the business. On the one hand, it has promoted the development of anti-counterfeiting technology and the development of new technologies and new materials; on the other hand, it has cracked down on counterfeit and shoddy goods in the market and protected the legitimate rights and interests of businesses. However, the reasonable choice of anti-counterfeiting methods and the reduction of production costs are businesses that cannot be neglected.

The meaning of anti-counterfeit: Anti-counterfeiting is not a new word. Since the patent right was protected, the anti-counterfeiting has arisen. However, when fake and shoddy goods flood the market, anti-counterfeiting becomes an inevitable demand. The application of today's anti-counterfeiting on labels or packages has exceeded the above requirements and implies the following implications.

1. To highlight the personalization of goods, especially when there are multiple substitutes for similar goods in the market;

2. If the latest product is displayed, even if the nature of the product does not change, it will become a new product after changing the label or packaging.

The way of anti-counterfeiting: The anti-counterfeiting protection of goods is two-fold. It not only protects the goods from the impact of fake and shoddy products, but also protects the interests of consumers from damage. Labels, like other packaging, must achieve the anti-counterfeiting purpose through the combination of processes, materials, processes, and materials.

1. Process security

That is, the printing of anti-counterfeit labels is carried out through special printing methods. Such as laser holographic technology, combined printing process (such as embossing, screen printing, flexo printing, printing code printing combination), can increase the difficulty of counterfeiting.

Process anti-counterfeiting technology mainly includes: anti-counterfeit printing plates, such as engraving gravure, special printing plates, etc.; anti-counterfeit printing graphics, such as printing precision shading, microtext, hidden text printing process security, such as rainbow printing, multi-color wiring printing. At present, in the label printing, there are not many manufacturers that use the above-mentioned methods for anti-counterfeiting printing. The reasons are as follows: First, high accuracy is required; they cannot match the existing label printers; second, the printing manufacturers are not skilled enough.

2. Material security

Process anti-counterfeiting is mainly applied in manufacturers with mature technologies, infrequent changes in processed products and complete processing equipment. There are mainly two types of anti-counterfeiting materials:

(1) Anti-counterfeiting of printing materials

Using the inherent security features of the label material to achieve the purpose of anti-counterfeiting, such as the adhesive material among the easy shredding, water-soluble paper, anti-uncovered paper (lifting the layer with and without information) and so on. This type of material has one common feature: it is not reusable. Either touch it and break it, or it will meet with water, and it will dissolve and disappear in the wet, or it will not be pasted after it is opened. These materials have their specific anti-counterfeiting purpose and application scope, and can realize the function of showing consumers and businesses whether to change the package. There is no need to rely on detection instruments. For example, tamper-resistant labels applied on mobile phones have relevant graphic information. However, such labels also have their disadvantages. Once these materials are popularized, the anti-counterfeiting function will disappear.

(2) Anti-counterfeiting of coloring materials

In the label printing, the anti-counterfeiting purpose is achieved by the coloring characteristics of the ink. Ink anti-counterfeiting is more pragmatic than anti-counterfeiting materials for printing materials, and has stronger anti-counterfeiting performance. It has become one of the most rapidly developing anti-counterfeiting high-tech technologies for packaging and printing. Compared with the anti-counterfeiting method for printing materials with a single function, the anti-counterfeit printing technology for coloring materials can achieve multiple anti-counterfeiting purposes. At present, the main application of coloring material anti-counterfeiting technology is as follows.

1 light variable ink anti-counterfeiting

When the viewing angle is changed by 60, the reflected light wave entering the human eye changes, and the observed image is different from the original. With different hue of light variable ink can get different observations.

Human eyes can be intuitively identified.

2 colorless fluorescent ink and phosphor ink anti-counterfeiting

A special luminescent material is added to the security ink so that the printed matter can show luminescent marking under ultraviolet irradiation; when there is no ultraviolet ray, the ink is invisible and invisible. The higher the whiteness of the paper, the more invisible the effect of ink, so the use of printing materials with low whiteness, anti-counterfeiting effect is obvious.

3 colored fluorescent ink and phosphor ink anti-counterfeiting

Similar to the function of colorless fluorescent ink and phosphorescent ink, only the ink of a certain color is added to the label print, and under the action of ultraviolet light, the effects of fluorescence and phosphorescence are obvious; when there is no ultraviolet light, only the true colors are displayed.

4 thermochromic ink security

Thermochromic inks use thermal energy to change the hue of the ink under heat, such as turning red, green, or black. Thermochromic ink anti-counterfeiting technology is divided into two kinds: reversible and irreversible.

3. Combination of craft and material security

The integrated anti-counterfeiting technology is an anti-counterfeiting technology that combines the above anti-counterfeiting technologies. Such as the use of special plate. Shows the printed materials and the special inks that have been replaced for packaging and are combined with each other to carry out process design. The label or trademark is then combined with a special pattern. Images and text are printed on the fine and fine shading with fluorescent ink or color-changing ink. At present, bar codes have been widely used, but they have not played a real anti-counterfeiting effect. This is mainly due to the lack of supervision and management of bar codes on the market. Consumers in the commodity market do not match the information held by the product manufacturer using the bar code. The invariable bar code plays the role of transmitting product information, and its anti-counterfeiting effect is weak. The variable bar code uses a computer to control the bar code and its code change, so that the printed bar code is different from each other, and is read by a special bar code scanner during identification. To distinguish between authenticity and falsehood. At present, this technology has been widely used. This shows that anti-counterfeiting technology is not a simple topic. When merchants adopt or require anti-counterfeiting, it also means that counterfeiters' counterfeiting technology has also been correspondingly improved. In particular, counterfeiters who have quite professional forgery techniques make anti-counterfeiting experts even more headaches. Therefore, the ability of consumers to fully understand commodities and have the ability to distinguish between authenticity and counterfeiting is the real anti-counterfeiting technology. Strictly control the special equipment, materials and processes required for anti-counterfeiting technology, strengthen the management supervision of anti-counterfeit labels, control the number of counterfeits from the source, strengthen inspections in circulation and sales to reduce the appearance of fake and shoddy products in the market. Opportunity to increase consumer's ability to distinguish between genuine and fake goods to reduce the desire of counterfeiters and increase the intensity of counterfeiting to increase the risks faced by counterfeiters. In short, regulating the market behavior and raising the awareness of consumers' own rights and interests is a powerful complement to anti-counterfeiting technology. In any case, the use of anti-counterfeiting labels is only one of the ways to achieve anti-counterfeiting purposes. To improve anti-counterfeit technology and reduce counterfeiting opportunities require joint efforts from various sectors of society.
