How to make the QR code anti-counterfeiting label

by:LG Printing     2021-08-25

Many companies are very concerned about the benefits of their own brands. When consumers buy products or seek services, they are more inclined to choose brands with better reputations. Therefore, in order to protect their own brand benefits and brand value, companies and manufacturers will stick anti-counterfeiting labels on their products. These anti-counterfeiting labels are coded on each product, and are printed directly in combination with the relevant information of the product, forming a label on the product, so that when the product is offline, the label will be directly attached.



In addition to setting up labels, companies and manufacturers have also created a central database In this way, the unique code of each product and the product information corresponding to this code can be stored, thereby establishing a complete anti-counterfeiting brand, so consumers only need to enter the code on the online access platform after purchasing the corresponding product You can check the authenticity. The existing anti-counterfeiting technology has been greatly improved, but it is generally printed or printed on the goods. This type of anti-counterfeiting technology is actually relatively easy to be copied and worn, and it is difficult to carry out daily Maintenance, so in this process, we must continue to improve the relevant production elements.


So now many companies have introduced more quality-guaranteed anti-counterfeiting labels, so what should they do?


First, we can choose a transparent material to make the substrate, and then polish the surface of the substrate, clean it and dry it. Print the two-dimensional code of the product on the polished surface, and set some irregular tiny dark spots on the edge of the two-dimensional code. These dark spots will not affect the recognition of the two-dimensional code. In addition, we can also set a ring-shaped organic film on the surface, so that it can surround the outside of the QR code, and these first organic films will not cover the dark spots. Then, the anti-counterfeit label organic film is irradiated with ultraviolet positive light to form the first area, and then irradiated to form the second area. The surface film made of transparent material is provided and covered with scratched silver. Then the two-dimensional code and the position of the dark spot are stored in the database and encrypted, and the whole set of anti-counterfeiting work can be completed.
