DIOVIS Colour Shift & Polarising film Brand Protection stickers

DIOVIS® Brand protection technology utilizes specific optical properties to enable accurate and easy visual validation by non-experts. This makes it easier to spot counterfeits, which protects clients from pirated products while defending corporate brand image.

The standard DIOVIS TG-80 is supplied in sticker form. The stickers incorporate delamination film to prevent re-use and may be laser-marked with brand name or code to facilitate traceability.

There are three levels of verification :-

1. Overt Colour shift effect from gold to green.
2. Covert checking with 'Handy Viewer' polarising film.
3. Machine verification using special sensor for high volumes.

TG-80N type DIOVIS is a transparent version which may be used for ID cards, photographs for passports etc.

Other types of DIOVIS are available on request.
