The realization of anti-counterfeiting labels is mainly based on various technical principles, and the effect of anti-counterfeiting is achieved by applying different methods. This article is an introduction to the technical principles and application methods of anti-counterfeiting labels:
1. Optical change technology: This technology uses optical effects or chemical reactions to produce color changes or pattern changes under different lighting conditions, so as to achieve anti-counterfeiting effects. For example, with special inks or pigments, different colors or patterns appear in a specific light, and hidden information can only be seen under a specified light source, making it difficult to reproduce.
2. QR code barcode anti-counterfeiting: using two-dimensional code or barcode technology, product information or code is encrypted and stored on the label, and consumers can verify the authenticity of the product by scanning these codes. This method requires a combination of special anti-counterfeiting algorithms and database systems to ensure the security and performance of the information.
3. RFID technology: Radio frequency identification technology (RFID) uses radio frequency to identify the information on the tag, and realizes product traceability and anti-counterfeiting by reading the radio frequency signal on the tag. Each RFID tag has an identification code that can effectively prevent counterfeiting and counterfeiting.
4. Nano micro marking: This technology uses nano-level micro marks or labels to add tiny marks to the surface of the product or packaging, which can only be identified and verified by special equipment. This method is highly concealed and anti-counterfeiting, making it difficult to copy and imitate.
5. Texture and structure design: By designing special textures or structures on the surface of the label, such as miniature concave and convex, miniature patterns, etc., the label presents a unique visual effect when observed, which is difficult to copy. This method usually incorporates optical change technology to increase the anti-counterfeiting effect.
The above are several common anti-counterfeiting label technology principles and application methods. In practical application, the appropriate technical solution is usually selected according to the characteristics and needs of the product, and multi-level anti-counterfeiting measures are taken to improve the anti-counterfeiting effect. The comprehensive use of a variety of technical means can effectively protect the safety and brand image of the product, and reduce the risk of counterfeit and shoddy products.
