Variable Information like alphanumeric sequential numbering on holograms significantly enhances security and provides ease of material tracking. Every single hologram could actually be unique!
Some suggested forms of Variable information on holograms may be:
Multi Digit Sequential Numbering
Promotional Catch Lines
Date Of Manufacturing
Such variable information can be tamper proof or even invisible under normal viewing condition.
All such variable Marking is done in-house on our
Laser Marking System: A high powered Laser beam is used to selectively remove the thin metal layers from the hologram. Effectively, the hologram gets demetallised at the point where the Laser strikes the surface. Any information thus 'written' on the hologram is now tamper proof. The variable information always appears in the colour of the surface on which the hologram is affixed, thus lending greater security.
Ink Jet Marking System: The desired information is overprinted with ink. Very small characters can also be printed with remarkable sharpness and clarity. A choice of colours is available to suit your needs.
UV Marking System: You also have the option of coding your variable information with UV inks, so that the variable information remains hidden and is only visible under a UV light source.
