SYSTEM FOR AUTHENTICATING UV ABSORBING SECURITY MARK |
摘要 |
A system for authenticating a document includes a document having a substrate comprising an optical brightener; printing a background with a ultraviolet (UV) absorbing material on the substrate comprising a first pattern of lines having a first frequency and a first orientation; printing a security mark with the UV material on the substrate comprising a second pattern of lines having a second frequency and a second orientation; a lenticular lens; placing the lenticular lens over the security mark and background; a UV lamp; illuminating the security mark and background through the lenticular lens with UV light; orienting the lenticular lens to match either the first orientation or the second orientation; and authenticating the document if the security mark matches a predetermined security mark. |
