1. UVA Visible Organic Fluorophore

UVA fluorescent pigments are widely known as fluorophores in security printing field, which is invisible under daylight and emission by ultra-violet ray at UVA 365nm. It is generally recommended to be used for level 2 security feature (Covert). NANOCMS supplies 6 organic UVA pigments:

2. UVC Visible Organic Fluorophore

Invisible under daylight but emission at UVC 254nm only gives higher security than UVA visible fluorophore. No emission by UVA ray after 320nm wavelength. Generally recommend to be used for a single UVC or combining with UVA for Bi-fluorescent which is higher level 2 security feature (Covert). NANOCMS supplies 2 organic UVC pigments:

3. UVA & UVC Visible (Bi-fluorescence) Organic Fluorophore

Besides the banknote printing, there have been many attempts to get higher level anti-counterfeiting printing in UV visible security feature. Combining UVA and UVC for Bi-fluorescent is one of the solutions but it is not simple because of uncommon supplier of high quality organic UVC pigments for offset as well as overlapping phenomenon of excitation wavelength. To meet this market demand, NANOCMS can provide 5 different colors:
