We have three types of invisible ink

	Bluish/White under UV - Isopropyl Alcohol Based
	Yellow under longwave UV - MEK Based *Requires 375nm or lower UV light. Lower works better.
	Red under UV - Acetone Based *Requires 385nm or lower UV light. Lower works better.
	UVunVisl - Only visible with a special UV camera and UV filter. Cannot be seen with a UV light, the human eye or infrared sources.
	IR Invisible Ink - Alcohol Infrared Ink - Fluoresces in the Infrared Range

The Isopropyl Alcohol based inks are well suited for:

	Hand Stamping for Access Control
	Writing on paper, cardboard, wood
	Porous Surfaces

The Acetone based inks are well suited for:

	Permanent marking on plastics
	Writing on painted surfaces
	Non-Porous, slick surfaces
