Optically Variable Device

There has been a great deal of recent interest in optical security technology. Optically variable devices (OVD) are based on materials and technology that change appearance when viewed from different angles. OVDs are capable of producing sophisticated optical images with an exceptionally high level of security features. The technique allows for the microprecision placement of pixels, which are forensically identifiable for maximum image clarity and security. Holographic technology, foil embossing equipment, application processes and information associated with security devices are the prime concerns in the adoption of these new security measures.
