LehMo-Flo Security Paper

UV-C Light
UV-A Light
Blue light + Filter
When viewed under natural light, the security paper appears like a standard document with no visible security features. However, under UV light, its fluorescent properties reveal embedded security marks, showcasing how our pigment-integrated paper provides enhanced anti-counterfeiting protection. Invisible under normal conditions yet detectable in the whole range of UV light (from UV C- UV A). With the use of an optical filter, the printed security marks can also be detected under visible light such as blue or green light. This solution is ideal for secure documents. In this example, the random fluorescent dots are visible under UV C, UV A and blue light (with a filter) but not in natural light.

While QR codes are increasingly used as an anti-counterfeiting measure, they remain vulnerable to manipulation and copying. To address this concern, we offer invisible QR codes for enhancing product security. These QR codes are designed to be readable only under special lighting conditions and display a unique color that is challenging to replicate.
