IMPROVEMENTS IN SECURITY SUBSTRATES |
摘要 |
The invention is directed toward improvements in security substrates, such as paper, used for making security documents, such as bank notes, having anti-counterfeit able features and in particular to security substrates incorporating an elongate security element and methods of making the substrate. The invention comprises a security substrate for making security documents and the like comprising a fibrous base substrate and an elongate security element at least partially embedded therein. At one surface of the security substrate one portion of the security element is exposed to provide a continuous track along the length of the security element. A plurality of other portions along at least one edge of the security element are partially covered by overlapping regions of the fibrous substrate. The invention further comprises a method of manufacturing such a security substrate. |
