Anti-counterfeit ink is a specialty printing ink that verifies authenticity through specific means. Here are the five main series explained.
1. UV Invisible Ink
Colorless in normal light, glows under 254/365nm UV. Covert, easy to verify, cost-effective — for tickets, IDs and packaging.
2. OVI Chameleon Ink
Color-shifting with viewing angle (gold-to-green, etc.), visible to the naked eye, extremely hard to counterfeit — for banknotes and premium packaging.
3. Thermochromic Ink
Changes color with temperature (custom 5-80°C), great for beverage labels and tamper-evident seals.
4. IR Excitation Ink
Emits visible fluorescence under IR, invisible normally, verified with dedicated devices — highest covertness for IDs and banknotes.
5. Photochromic Ink
Develops color under sunlight/UV and fades without light — for tags, cosmetics and tickets.
