UV fluorescent ink, invisible anti-counterfeit ink, UV reactive printing ink
Introduction
Against the backdrop of stricter global anti-counterfeiting standards, UV fluorescent ink has become the most popular invisible printing material for security production. Unlike ordinary printing ink, professional UV fluorescent ink is invisible under natural daylight and glows vividly under 365nm ultraviolet light. This invisible anti-counterfeit ink delivers hidden marking functions that hologram or regular ink cannot match. Many printing factories and brand packaging suppliers now replace traditional anti-counterfeiting materials with stable UV fluorescent ink to upgrade product authenticity verification.
How Does UV Fluorescent Ink Work?
The luminous effect of UV fluorescent ink comes from high-purity fluorescent pigment inside the ink system. The special fluorescent pigment is colorless on paper, PET, PVC and other substrates without UV irradiation. Once exposed to 365nm ultraviolet light, the pigment absorbs UV energy and releases bright visible light, forming clear patterns printed by the invisible anti-counterfeit ink.
This photoluminescence reaction of UV fluorescent ink is reversible. After turning off the UV lamp, all fluorescent traces disappear instantly, maintaining perfect concealment. Our factory’s customized UV fluorescent ink strictly controls pigment particle size to avoid precipitation, ensuring uniform luminous performance for long-term printing production. Whether you use screen printing or offset printing, this UV reactive printing ink can maintain consistent luminous brightness without color fading.
