Colourless stamping ink visible as blue fluorescent colour under UV light at a wavelength of 366 nm. For porous surfaces.

This ink is particularly popular as an admittance stamp on hands in discotheques or for other special effects in the dark. It is also recommended for natural coloured cardboard boxes, paper sacks and similar absorbent materials.

Note: White paper products are unsuitable for security markings because they have an optical brightener which illuminates with the same colour in the same wavelength range. (In such cases use stamping ink 1073 P.)

Drying time: ~15 sec. smudge-proof (paper).

Stamp material: Rubber or special photopolymers.

Stamp pad material: For manual stamping Coloris office stamp pads or felt plate pads are recommended.
For automatic marking, presses with rubber or foam rubber ink rollers which operate with ink reservoirs are preferable.
