Introduction
UV invisible ink (UV fluorescent ink) is a special printing material with fluorescent compounds evenly dispersed in an eco-friendly resin system. It appears colorless or with a fixed base color in normal light; under UV (254nm short-wave / 365nm long-wave) it instantly emits bright red, green, blue or yellow fluorescence which disappears when the light source is removed. Dual-wavelength versions display different colors under different wavelengths, greatly raising the anti-counterfeit barrier.
