LATITUDE™ is a first of its kind security feature. It is the world’s first diffractive optical effect to be generated by a diffractive structure embedded in the substrate layer and coated with silver nanoparticles.
As an embedded structure within a clear window, LATITUDE™ can be designed in any area on the note and its visuals can be observed in any orientation which provides easy authentication.
LATITUDE™ is unique in its ability to deliver diffractive optical effects while also creating a semi-opaque appearance. If the feature is held up to light it turns a single colour with the viewer able to see through the note. This dual effect – diffractive optical effects using reflected light, and see-through capability using light in transmission – makes LATITUDE™ highly complex for counterfeiters to replicate.
As a printed feature using silver nanoparticles, LATITUDE™ offers complete design flexibility. This is a standout benefit against other more restrictive mediums that are applied as a stripe or patch. LATITUDE™ can be featured in any location within a window area, enabling unlimited design possibilities.
LATITUDE™ delivers eye-catching effects in both reflection and non-direct light transmission, allowing for instant authentication by the user.
