Security Pigments for Anti-counterfeiting
LehMo-Flo and LehMo-Glow
LehMoSense GmbH produces pigments for printing security marks for anti-counterfeiting.
​
Using our photoluminescent pigments, you create and let users view the hidden security mark (color) under invisible UV light or view the fading color after switching off the UV or visible light
LehMo-Flo Pigments
Our LehMo-Flo products are photoluminescent pigments/phosphors suitable for anti-counterfeiting applications. They emit unique color of light under ultra-violet (UV) light. The emitted color is invisible in ambient light. UV pigments are generally used as security marks on banknotes and other important documents that need protection against counterfeits. Importantly, all LehMoSense's products do not contain rare-earth elements whose production destroy and pollute the environment. Additionally, our products to not contain toxic substances such as Formaldehyde found in most traditional pigments. The images below represent our three pigment samples.

Our fluorescent security paper offers a possibiliy to use special laser technology to print security features that are invisible in ambient light but visible under UV light. This is demonstrated here by a printed text (LehMoSense GmbH) that becomes visible only when illuminated by UV light.
Secure QR codes

Despite the increasing use of QR codes as an anti-counterfeiting measure, they are also very vulnerable to manipulations or copying. For this reason, secure QR codes with anti-copying features, have become indispensable. We can print QR codes that are readable only under UV light and also show a unique colour that is difficult to copy. This can protect many products that are prone to counterfeiting such as pharmaceuticals, luxury or precious goods.

Afterglow excited by visible light
Most materials show afterglow property only when illuminated by UV light and not by visible light. This limits further applications since UV light is unsafe. Furthermore, the afterglow from most materials do not perform well at temperatures above 30 degrees Celsius. Our LehMo-Glow samples overcomes the above mentioned drawbacks since the afterglow is excitable by visible light (including white light) and the afterglow is observable by naked eye even at higher temperatures upto 40 degree Celsius. Please see the images below.
