Invisible infrared ink
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 Absorbing Ink (Invisible Infrared Ink)
The ink is often used to print code, and use identify pen as testing tools.
