Ultraviolet Security Ink
'This ink is only visible when exposed to an ultraviolet light source'
What is ultraviolet?
Ultraviolet is not perceptible to the human eye. The electromagnetic radiation falls just outside the observable spectrum of the human eye. Ultraviolet is often abbreviated as UV or referred to as ultraviolet radiation, black light or UV light.
The wavelength of ultraviolet radiation is between 10 and 400 nanometers, so it goes 'beyond the color spectrum of violet', which is also the literal meaning of 'ultraviolet'.
Ultraviolet security ink
Although ultraviolet is not visible to the naked eye, we can perceive it as radiation. That means that when ultraviolet ink is exposed to a source of ultraviolet light, this ink lights up and becomes visible.
Different colors are available.
Transparent ultraviolet security ink
Under normal light conditions the unique identification printed with ultraviolet ink is invisible to the human eye, when exposed to ultraviolet radiation it is visible. This version is available in various colors.
Metallic ultraviolet security ink
This ultraviolet variant is processed in metallic ink. Under normal lighting conditions, only gold or silver printing can be seen. The unique identification is only visible when exposed to ultraviolet radiation.
