Luminous stamping ink 948
Colourless stamping ink visible as intensive blue fluorescent colour under UV light at a wavelength of 366 nm.
Properties:
Dries slightly more slowly on smooth, non-porous surfaces. This ink is not suitable for marking human skin
(like luminous stamping ink II or III) Ink 948 can also be used in felt-tip pens.
Application:
We recommend this stamping ink for coloured or natural coloured paper, cardboard and other absorbent materials.
Note:
White surfaces are suitable for security markings only in extremely rare cases because they frequently have an optical brightner which illuminates with the same colour in the same wavelength range. In these cases it is better to use the luminous stamping ink 4430 P yellow!
Drying time:
~90sec smudge-proof (metal)
Viscosity:
low viscosity, ~12sec
(Ford 4mm cup)
Stamp material:
Rubber
Stamp pad material:
For manual stamping, we recommend our office stamp pads with felt inserts
or felt plate and SOLI plate pads. For automatic marking, presses with rubber ink rollers which operate with ink reservoirs are preferable.
