TRILUMIC® - Hidden halftone design feature
Incorporated in high security foils, TRILUMIC® expands the authentication level 1 properties of the hologram with a new level 2 feature. Hidden under daylight this complex security feature is placed in perfect register on the holographic stripe. Under UV light it shows an extremely brilliant true colour halftone image which cannot be realized on paper surface but on foil. The special technology of the feature in combination with the de-metallized area of a holographic stripe ensures attractiveness for the public, interesting opportunities for banknote designing and a significant barrier for counterfeiters.
TRILUMIC® is a trademark resulting from a cooperation between HUECK FOLIEN and Banque de France.
