Abstract

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.

Claims

1. A method of making an identification document comprising:

providing image information, the image information being arranged to include at least two different images;

using pressure to form a lens profile in a laminate, including combining the laminate with ink or dye representing the image information to form the document;

the document being 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.

2. The method of claim 1 wherein the image information represents variable information associated with a bearer of the document

3. The method of claim 1 wherein the ink or dye comprises inks or dyes of different colors to form color image information.

4. The method of claim 1 wherein at least one of the two different images comprises an image of the bearer.

5. An information bearing document comprising:

a core layer;

an image layer depicting at least two different images;

a laminate layer;

the laminate layer being 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.

6. The document of claim 5 wherein the image layer represents variable information associated with a bearer of the document

7. The document of claim 5 wherein the image layer comprises inks or dyes of different colors to form color image information.

8. The document of claim 5 wherein at least one of the two different images comprises an image of the bearer.
