UV invisible ink is a standard choice for cigarette package security thanks to its covertness, easy verification and controlled cost.
Advantages
Colorless in normal light, invisible to the naked eye, UV invisible ink reveals fluorescent patterns only under a 254/365nm UV lamp. Consumers verify with a currency detector while counterfeiters can hardly spot the mark, greatly raising the copying difficulty.
Typical Applications
- Covert fluorescent patterns and text on cartons and packs
- One-code-one-item covert coding with inkjet printing
- Combined with OVI ink for a dual-layer defense
- Plus thermochromic ink for a three-layer system
