Security threads are a highly effective and good value long-lasting security feature. Widely recognized by the public, security threads are extremely complex to produce to ensure protection against counterfeiting.

Security foil elements are easy-to-authenticate security features with striking designs across a prominent area of a banknote. Security foils ensure high recognition and design flexibility, incorporating gold, copper, or aluminum effects. Exclusive and sophisticated origination technologies are used to create customer-specific designs that are secure against counterfeiting.

Printed features using optically variable inks (OVIs) create alluring anti-copy security features that enable fast authentication of banknotes. Printed features create effects that depending on the angle of view are either visible, change color or vanish when the banknote is tilted.
