Remedium’s UV Invisible Fluorescent Security Inks are specially formulated for high-security printing on both offset and flexo machines. These inks remain invisible under normal light but fluoresce brightly under UV (black) light, making them ideal for anti-counterfeiting and authentication applications. Compatible with paper, plastic, and label substrates, they offer excellent printability, fast curing, and long-lasting performance. Perfect for currency, tickets, labels, and brand protection packaging.
