This high-end, long-lasting, and stable anti-counterfeiting ink features infrared-activated color development and excellent covert properties; it is compatible with various substrates and suitable for screen, offset, and flexographic printing.

Infrared-excited invisible ink emits distinct fluorescence when exposed to infrared equipment while remaining completely invisible to the naked eye, offering a high level of covert security. It is compatible with various printing processes—including screen, flexographic, and offset printing—and exhibits strong adhesion across substrates such as paper, plastic, and laminated materials. The ink is resistant to abrasion, solvents, and weathering without degradation; it is eco-friendly and free of heavy metals. Suitable for anti-counterfeiting applications on documents, packaging, labels, and credentials, it is difficult to replicate yet easy to verify, making it ideal for integration with automated infrared inspection systems and high-volume industrial printing.
