Multiple Image Security Features for Identification Documents and Methods of Making Same
摘要:
An identification document manufacturing method makes an identification document with an optically variable security feature by forming a lens structure in the document's lamination layer along with image information. The method provides image information arranged to include at least two different images. The method uses pressure to form a lens profile in a laminate, including combining the laminate with ink representing the image information to form the document. The document is formed together with the laminate and ink such that the lens profile enables display of the at least two different images when the document is viewed at different predetermined angles. An information bearing document comprises a core layer, an image layer depicting at least two different images, and a laminate layer. The laminate layer is pressed on the core layer such that it forms a lens profile that enables display of the at least two different images when the document is viewed at different predetermined angles.
