UV invisible ink is a specialized printing material designed for covert marking and security applications. When exposed to ultraviolet (UV) light, this ink becomes visible, allowing for discreet yet traceable identification. It is widely used in UV inkjet printers for high-precision coding on various substrates, including paper, plastics, metals, and glass.
Key Functions:
Security & Anti-Counterfeiting: The ink remains invisible under normal light, making it ideal for authentication marks on tickets, certificates, and high-value products.
Traceability: Manufacturers use it for batch numbers, QR codes, or barcodes in logistics and pharmaceuticals without affecting product aesthetics.
Tamper Evidence: Hidden markings reveal attempts at alteration when viewed under UV light.
Technical Advantages:
Fast Curing: UV inkjet printers instantly cure the ink via UV lamps, ensuring smudge-proof results.
Durability: Resistant to water, heat, and abrasion, suitable for harsh environments.
Compatibility: Works with high-speed industrial printers for continuous production lines.
Common Applications:
Packaging: Hidden expiry dates or manufacturing details.
Electronics: Circuit board labeling without visual clutter.
Banking/Government: Secure documents like passports or currency.
