The invention relates to a security device for security substrates, such as paper, used for making security documents, such as bank notes, having anti-counterfeitable features. The security device comprises a carrier 11 of an at least partially light transmitting polymeric material, the carrier being provided with indicia. The indicia comprise a first component being at least one non-alphanumeric pattern 13 which repeats along the length of the device and is formed from at least one fine line, and a second component being alphanumeric characters 12, the two components being registered to and interlinked with each other. The pattern 13 directs the eye to the alphanumeric characters 12. The pattern may frame the characters. The device may be produced by partial demetallisation of a metallised carrier film. |
