Detailed Product Description

Invisible infrared ink has two kinds, one called absorbing ink, another called irradiating ink
Absorbing ink, wavelength is 800nm-850nm, irradiating ink, wavelength is 980nm – 1050nm,
documents printed by the two kinds of ink, are all invisible to naked eye, but testing tools for the two kinds of ink, is different. To absorb ink, we use IR camera and our identify pen product as tools, under IR camera, the document will be seen as black color. To irradiating ink, we only use 980nm laser Led as tools, when 980nm light irradiate the ink, will give out green dot, blue dot, red dot,yellow dot, etc.

Infrared Irradiating Ink (Invisible Infrared ink)

Type:Y0-100, transparent ,under 980nm laser Led,give out green.
Type:Y0-101, transparent ,under 980nm laser Led,give out red.
Type:Y0-102, transparent ,under 980nm laser Led,give out blue.
Type:Y0-103, transparent ,under 980nm laser Led,give out yellow.
 
Infrared Absorbing Ink (Invisible Infrared Ink)
The ink is often used to print code, and use identify pen as testing tools.

Type:Y1-100, ink is blue or green, printing effect is invisible
 
Infrared cover ink

Type : Y3-100, The ink looks like black, but under IR camera is transparent, so IR camera can see other thing hidden under the cover ink, for example, you can print character "A" first,  then use the cover ink print other things on the surface of "A", So people only can see the things printed by cover ink, but under IR camera, you can see character "A".
"under IR camera, the barcode hidden the black strip will be seen ."
"surface is a black strip, a barcode is covered by this black strip, but you can not see it . "
