Security devices, their production and use |
摘要 |
Security documents, such as passports, bank notes and credit cards, often incorporate security devices that are difficult to replicate by conventional printing or copying techniques. Disclosed herein are security devices and methods for their production. In selected embodiments, the security devices may be used with polymer core materials in such a way that they simulate the appearance of known security devices more traditionally used with paper or other core materials. |
