Security Thread Substrates
Viavi OSP offers ChromaGuard™ and ChromaShutter™ security substrate materials for optically-variable threads are designed to be embedded in banknote paper during the paper-making process. These materials provide banknote designers a wide range of compelling overt effects to deliver a strong overt security component to banknote design. An overt feature such as a thread, which can be embedded into currency paper, adds a substantial layer of complexity that is very difficult for criminals to counterfeit successfully.
Viavi OSP security substrates are sold to a restricted group of accredited customers that convert this material to thread and paper.
