Anti-counterfeiting ink selection guide: from demand matching to compliance selection, build a strong commodity safety defense line
With the iterative upgrading of counterfeiting technology, anti-counterfeiting ink, as an "invisible guard" of commodity safety, is directly related to brand credibility and market order. However, in the face of diverse categories such as thermal sensitivity, fluorescence and magnetism, how can enterprises accurately select suitable products? Industry experts combined standard norms and practical cases to give a systematic solution.
Category matching: select core anti-counterfeiting technologies on demand
The selection of anti-counterfeiting ink should first follow the principle of "scene adaptation", and different application scenarios need to match the exclusive technical characteristics. The field of financial bills has strict security requirements. Priority can be given to the use of composite anti-counterfeiting ink that integrates miniature text and fluorescent reactions. For example, the customized scratch ink adopted by a bank can not only ensure information security through anti-light transmission, but also achieve rapid verification with the help of special anti-counterfeiting elements.
The packaging of daily consumer goods needs to balance the anti-counterfeiting effect and the convenience of identification. Ultraviolet-excited fluorescent ink is the best choice because of its moderate cost and simple identification. It can show specific fluorescence under 365-395 nanometers of ultraviolet light, and the anti-counterfeiting effect of inorganic fluorescent materials can be maintained for more than 10 years. High-end goods such as luxury goods are suitable for optical variable anti-counterfeiting ink, which changes color with the change of observation angle. The technical threshold is high and difficult to counterfeit, similar to the magnetic optical gradient ink characteristics used in the new version of RMB.
Three elements of model selection: performance, compliance and practicality are indispensable.
After determining the category, it is necessary to thoroughly verify the suitability of the product from three dimensions. In terms of performance, covering power and tolerance are the core indicators: scratching applications need to ensure that the ink is impermeable under strong light, and the coating is uniform and easy to scratch ; outdoor use scenarios should pay attention to weather resistance to avoid the failure of anti-counterfeiting characteristics caused by long-term ultraviolet irradiation.
Compliance is the bottom line requirement of model selection. It is necessary to strictly verify whether the product meets the national standards such as GB/T 22467.2 Anti-counterfeiting Materials Part 2: Anti-counterfeiting Ink and Printing Oil. At the same time, pay attention to the VOCs content and heavy metal limit. For example, offset printing ink should meet the environmental protection regulations of HJ 2542 "Environmental Marking Product Technical Requirements for Oset Printing Ink". Set . Printing related to children's products must meet the requirements of GB 6675.4 "Toy Safety Part 4: Migration of Specific Elements" to eliminate harmful elements exceeding the standard.
Practical adaptability is also crucial. The printing method directly affects the choice of ink: convex printing and gravure printing need to correspond to the exclusive ink type, and the screen printing scene can give priority to UV-curing anti-counterfeiting ink. At the same time, the compatibility of ink and printing should be tested in advance. Paper, PET, PVC and other different materials need to match the corresponding ink formula to avoid poor adhesion or abnormal color development.
Market Tips: Beware of low-price traps and pay attention to technical services
At present, the quality of anti-counterfeiting ink products in the market is uneven. Some enterprises choose inferior raw materials to reduce costs, resulting in the failure of the anti-counterfeiting effect or the existence of hidden environmental protection hazards. Experts remind that when selecting models, priority should be given to regular manufacturers with test reports. If necessary, the anti-counterfeiting characteristics and safety index test certificates of third-party authoritative institutions can be required.
In addition, technical service ability is also an important consideration. For example, in AR interactive marketing, a fast-moving consumer brand has achieved the dual needs of anti-counterfeiting and interaction through the manufacturer's customized scratch ink, which is inseparable from the printing process guidance and post-production technical support provided by the manufacturer. For batch application scenarios, it is recommended to carry out a small batch trial printing first to verify the stability and anti-counterfeiting effect of the ink in the actual production process.
Industry insiders pointed out that the essence of the selection of anti-counterfeiting ink is to build a triple protection net of "technical adaptation + standard compliance + practical work". With the deep integration of AR, intelligent identification and other technologies with anti-counterfeiting ink, the future selection also needs to take into account the upgrading space of anti-counterfeiting technology to meet the continuously evolving challenges of counterfeiting with dynamic protection.
