How to choose anti-counterfeit ink? This is the first question brand owners and packaging printers face. Different series differ in principle, verification and application. Here is a quick guide to the five main series.
1. UV Invisible Ink
Colorless in normal light, glows under 254/365nm UV. Covert, cost-effective, easy to verify — ideal for labels, tickets, IDs and tobacco/alcohol packaging. Offset, screen and flexo compatible.
2. OVI Color-Shifting Ink
Shifts color with viewing angle, visible to the naked eye without any device, extremely hard to counterfeit. Used for banknotes, passports and premium packaging.
3. Thermochromic Ink
Changes color with temperature (custom 5-80°C triggers). Combines security with fun marketing for beverage labels, seals and medicine temperature indication.
4. IR Excitation Ink
Emits visible fluorescence under IR light, invisible normally, verified only with dedicated devices — the highest covertness for IDs, banknotes and documents.
5. Photochromic Ink
Develops color under sunlight/UV and fades without light — no equipment, novel effect for tags, cosmetics and tickets.
