LehMo-Flo Security Paper

Natural Light

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.

With our special ink, we can print invisible patterns to act as background on documents such as IDs, passports, certificates etc. The printed patterns are visible under UV light and also when illuminated by blue or green light and viewed through an optical filter.

Invible Secure QR codes

Invisible QR codes.jpg

      UV 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.
