GB/T 17001.1-2011 "Anti-counterfeiting inks - Part 1: Ultraviolet excited fluorescent anti-counterfeiting inks" specifies the classification, requirements, test methods, and other contents for such anti-counterfeiting inks used in paper printing. It is applicable to inks for single-color and multi-color paper printed products. The standard covers physical indicators and anti-counterfeiting characteristic requirements, defining key parameters such as fluorescence resistance to heat and light, while resistance to ethanol and gasoline are optional test items. Testing requires instruments such as a printability tester, a 254nm or 365nm ultraviolet light source with a power of not less than 5W, glass beakers, and tweezers. Performance is evaluated through the preparation of printed samples and immersion tests, providing a standard basis for ink quality control.
