Luminous stamping ink ST
Colourless stamping ink visible as intense blue fluorescent colour under UV light at a wavelength of 366 nm. Soaks into porous surfaces quickly.
Properties:
This ink is particularly popular as an admittance stamp on hands in discotheques or for other special effects in the dark. Also available as slow drying version (LT).
Application:
We recommend this stamping ink for natural coloured cardboard boxes, paper sacks, paper and similar absorbent materials.
Note:
White paper products are highly unsuitable for security markings only in extremely rare cases, because they have an optical brightner which illuminates with the same colour in the same wavelength range. (In such cases use 1073 P yellow !)
Drying time:
~5sec smudge-proof (paper)
skin
Viscosity:
low viscosity, ~12sec
(Ford 4mm cup)
Stamp material:
Rubber or special photo polymers
Stamp pad material:
For manual stamping, we recommend our COLORIS office stamp pads with felt inserts or felt plate and SOLI plate pads. The ink remains moist for stamping
for a long period without drying out in stamp pads. For automatic marking, presses with rubber ink rollers or foam rubber which operate with ink reservoirs are
preferable.
