Introduction
IR excitation ink (infrared security ink, up-conversion ink) is a high-covertness security ink that emits visible fluorescence when excited by infrared light. Completely invisible to the naked eye under normal conditions, it requires dedicated infrared detection equipment, making it one of the highest-level anti-counterfeit solutions for IDs, banknotes and documents.
Features
- Extreme covertness: invisible under normal light
- High security: verified only with IR source + viewing device
- Can be combined with UV invisible ink for a dual-channel security system
- Custom excitation wavelengths and multi-level security options
Applications
- High-security IDs, passports and credentials
- Banknotes, securities and invoices
- Tobacco, liquor and premium brand protection
Verification
An IR excitation light source with a viewing device reveals the fluorescence instantly and accurately.
