The application of anti-counterfeiting technology in the label printing industry

whether for the consideration of improving the added value of goods or to highlight the uniqueness of goods, anti-counterfeiting technology has become the focus of attention of businesses. On the one hand, it promotes the development of anti-counterfeiting technology and the research and development of new processes and new materials; On the other hand, we will crack down on fake and shoddy commodities in the market and protect the legitimate rights and interests of businesses. However, reasonable selection of anti-counterfeiting methods and reduction of production costs are issues that businesses cannot ignore

the meaning of anti-counterfeiting

anti counterfeiting is not a new word. Anti counterfeiting has arisen since the patent right was protected, but it has become an inevitable demand when fake and shoddy goods flooded the market. Today's application of anti-counterfeiting in labels or packaging has exceeded the above requirements, but also implies the following meanings

1. Highlight the "personalization" of commodities, especially when there are multiple substitutes for similar commodities in the market

2. Display the latest goods. Even if the nature of the goods has not changed, it will become a new product after changing the label or outer packaging

anti counterfeiting methods

anti counterfeiting has a two-sided protective effect on commodities, which not only protects commodities from the impact of fake and shoddy products, but also protects consumers' interests from damage. Like other packages, labels achieve the purpose of anti-counterfeiting by means of technology, materials, and the combination of technology and materials

1. Process anti-counterfeiting

refers to the printing of anti-counterfeiting labels through special plate making and printing. For example, laser holographic technology and combined printing processes (such as embossing, printing, flexo printing, and combination of inkjet printing methods) can increase the difficulty of forgery

process anti-counterfeiting technology mainly includes: printing plate anti-counterfeiting, such as engraving gravure, special printing plate, etc; Printing graphic anti-counterfeiting, such as printing precise shading, micro text, hidden text printing process anti-counterfeiting, such as rainbow printing, multi-color wiring printing, etc. At present, there are not many manufacturers using the above-mentioned methods for anti-counterfeiting printing in label printing. The reasons are as follows: first, the accuracy requirements are high, which cannot match the existing label printing machines; Second, the printing factory is not skilled enough

2. Material anti-counterfeiting

process anti-counterfeiting is mainly used in manufacturers with mature technology, infrequent changes in processing products, and complete processing equipment. Material anti-counterfeiting mainly includes the following two categories:

(1) printing material anti-counterfeiting

use the inherent anti-counterfeiting characteristics of label materials to achieve the purpose of anti-counterfeiting, such as fragile paper, water-soluble paper, anti uncovering paper (uncovering layer with information or without information), etc. This kind of material has a common feature, that is, it can not be reused. It can be broken at one touch, dissolved and disappeared in water and humidity, or it can't be pasted after being uncovered. These materials have their specific anti-counterfeiting purposes and application scope, which can realize the function of showing consumers and businesses whether to change the packaging secretly, and should be elastic and suitable. There is no need to use testing instruments. For example, the anti uncovering label applied on the has relevant graphic information. However, such labels also have shortcomings. Once these materials become popular, the anti-counterfeiting function will disappear

(2) colored material anti-counterfeiting

in label printing, the anti-counterfeiting purpose is achieved through the color rendering characteristics of ink. Ink anti-counterfeiting is more practical than the anti-counterfeiting of printing materials, and its anti-counterfeiting performance is stronger. It has become one of the fastest-growing packaging and printing anti-counterfeiting high-tech. Compared with the anti-counterfeiting method of printing materials with single function, the anti-counterfeiting of coloring materials combined with printing technology can achieve multiple anti-counterfeiting purposes. At present, the main anti-counterfeiting technologies of coloring materials are as follows

① light change ink anti-counterfeiting

when the viewing angle changes by 60 °, the reflected light wave entering the human eye changes, and the observed image is different from the original. Different observation effects can be obtained by using light variable inks with different hues. Human eyes can visually recognize

② colorless fluorescent ink and phosphorescent ink anti-counterfeiting

add specific luminous materials to the anti-counterfeiting ink, so that the printed matter can show the secret mark of luminescence under ultraviolet radiation; Without ultraviolet light, the ink is invisible. The higher the whiteness of the paper, the worse the invisible effect of the ink, so the anti-counterfeiting effect is obvious by using the substrate material with low whiteness

③ colored fluorescent ink and phosphorescent ink anti-counterfeiting

and colorless 8 Measurement error: ± 1% FS fluorescent ink has the same effect as phosphorescent ink, but the effect of fluorescence and phosphorescence is obvious only when adding an ink of a certain color to the label print under the action of ultraviolet light; When there is no ultraviolet light, only the natural color is displayed

④ thermochromic ink anti-counterfeiting

thermochromic ink uses heat to make the oil set a high industry standard, and the hue of the ink changes under the action of heat, such as turning red, green or black. Thermochromic ink anti-counterfeiting technology is divided into reversible and irreversible

3. Combined anti-counterfeiting technology of process and material

comprehensive anti-counterfeiting technology is an anti-counterfeiting technology that combines the above anti-counterfeiting technologies. If special plate making is adopted. The printing materials and special inks that show the stolen packaging are combined with each other for process design, and then the labels or trademarks are made in combination with special patterns. The images and words are printed with fluorescent ink or color changing ink on the exquisite and fine shading

at present, bar codes have been widely used, but there is no real operation mode: full automation plays an anti-counterfeiting role, which is mainly due to the inadequate supervision and management of bar codes in the market. It is caused by the mismatch between the information held by consumers and commodity manufacturers using bar codes in the commodity market. Invariant bar code plays a role in transmitting commodity information, and its anti-counterfeiting effect is very weak; Variable bar code is to use the computer to control the bar code and its code change, so that the printed bar code is different. When identifying, it is read by a special bar code scanner to distinguish the true and false. At present, this technology has been widely used

it can be seen that anti-counterfeiting technology is not a simple topic. When businesses adopt or require anti-counterfeiting, it also means that the forgery technology of counterfeiters has been improved accordingly. In particular, counterfeiters with quite professional forgery technology are a headache for anti-counterfeiting experts, so it is the real anti-counterfeiting technology to let consumers fully understand the goods and have the ability to distinguish the authenticity. Strictly control the special equipment, materials and processes required by the anti-counterfeiting technology, strengthen the management and supervision of the anti-counterfeiting logo, control the number of counterfeits from the source, strengthen the inspection in the circulation and sales links to reduce the opportunities of fake and shoddy products in the market, improve the consumers' ability to distinguish the authenticity of goods to reduce the desire of counterfeiters, and strengthen the fight against counterfeiting to improve the risks faced by counterfeiters. In short, standardizing market behavior and improving consumers' awareness of the protection of their own rights and interests are powerful supplements to anti-counterfeiting technology

in any case, the use of anti-counterfeiting labels is only one of the ways to achieve the purpose of anti-counterfeiting. Improving anti-counterfeiting technology and reducing the opportunities for counterfeiting require the joint efforts of many sectors of society
