UV Fluorescent Invisible Security Ink

タイトルまたは説明

Fluorescent ink, it’s kind of transparent ink, often to be called invisible ink. Under irradiation **0~ **0 nm light, the invisible ink gives out **0 ~ **0 nm visible light, and the color can be red, yellow, blue, green. Fluorescent ink depends on the different irradiation wavelength, there are two kinds.
Irradiation light wavelength **4 nm, the ink is called short wavelength, Irradiation light wavelength **5 nm, the ink is called long wavelength, long wavelength ink can be irradiated by both **4nm and **5 nm light, but short wavelength ink only can be irradiated by **4nm light.
Invisible UV ink, under common environment, it’s transparent, under UV light, it’s can be seen as yellow, green, red, or blue. Type and usage
long wavelength invisible ink
 TYPE：Y****0， transparent, irradiated by **5nm, change to green.  TYPE：Y****1， transparent, irradiated by **5nm, change to red. TYPE：Y****2， transparent, irradiated by **5nm, change to blue. TYPE：Y****3， transparent, irradiated by **5nm, change to yellow. Short wavelength(**4nm) invisible ink.  Solution of invisible UV ink printing
