GB/T 17001.5-2024 "Anti-counterfeiting ink - Part 5: Pressure-sensitive anti-counterfeiting ink" is a national standard for regulating pressure-sensitive anti-counterfeiting ink. Pressure-sensitive anti-counterfeiting ink refers to inks that can produce discoloration effect under pressure or friction, and is often used for anti-counterfeiting of printing products. The standard provides the product classification of such inks, and clearly stipulates its technical requirements, detailed test methods, inspection rules, Encasement, storage and other quality control links, which are applicable to the whole process of its research and development, production, inspection and sales. In order to verify its anti-counterfeiting and physical performance, the test method described in the standard requires the use of Printability Tester to prepare standard samples, sunscreen for Lightfastness testing, and Pencil hardness tester to inspect the Hardness and adhesion of the ink layer. In addition, in the identification and analysis of the anti-counterfeiting characteristics of inks, the document inspection instrument with multi-band Illuminant and image analysis functions is also a commonly used professional testing equipment.
