Abstract

A credential product is provided. The credential product includes a credential substrate, a translucent layer and an imageable layer. The imageable layer is positioned between the credential substrate and the translucent layer. At least a portion of the imageable layer is configured to form an image upon exposure to electromagnetic radiation. The image is visible through the credential substrate and is considered an imaged watermark.

Claims

1. A credential product comprising:

a card substrate;

a translucent layer; and

an imageable layer positioned between the card substrate and the translucent layer,

wherein portions of the imageable layer are exposed to electromagnetic radiation and are configured to change from a first level of opacity to a second level of opacity to form an image.

2. The credential product of claim 1, wherein the card substrate is translucent.

3. The credential product of claim 1, wherein the first level of opacity is less than the second level of opacity.

4. The credential product of claim 1, wherein the imageable layer comprises a photo-reactive chemistry that changes the imageable layer from the first level of opacity to the second level of opacity upon exposure to laser radiation.

5. The credential product of claim 1, wherein the imageable layer comprises an infrared absorbing material that changes the imageable layer from the first level of opacity to the second level of opacity upon exposure to infrared radiation.

6. The credential product of claim 1, wherein the translucent layer is configured to receive a printed image.

7. The credential product of claim 1, wherein the translucent layer formed on the top surface of the imageable layer comprises printed material.

8. The credential product of claim 1, wherein the translucent layer comprises a polyvinyl chloride film.

9. The credential product of claim 1, further comprising a transparent layer positioned on the translucent layer.

10. The credential product of claim 9, wherein the transparent layer is configured to receive a printed image.

11. The credential product of claim 10, wherein the printed image received by the transparent layer comprises a personalized printed image containing personal information related to a holder of the credential product.

12. The credential product of claim 11, wherein the personalized printed image received by the transparent layer corresponds with the image formed in the imageable layer.

13. A method of forming an imaged watermark comprising:

forming a credential product that includes an imageable layer positioned between a card substrate and a translucent layer; and

applying electromagnetic radiation to the imageable layer such that the imageable layer changes from a first level of opacity to a second level of opacity to form an image.

14. The method of claim 13, further comprising providing a transparent layer on the translucent layer.

15. The method of claim 13, further comprising printing an image on the transparent layer that corresponds with the image formed in the imageable layer.

16. The method of claim 13, wherein the card substrate comprises a translucent material that allows transmission of visible light such that the image formed in the imageable layer is visible through the card substrate.

17. The method of claim 13, wherein the translucent layer comprises a translucent material that reflects and transmits visible light such that the image formed in the photo-reactive layer is completely invisible to at least partially visible.

18. A credential product comprising:

a credential substrate;

a translucent layer; and

an imageable layer positioned between the credential substrate and the translucent layer,

wherein at least a portion of the imageable layer is configured to form an image upon exposure to electromagnetic radiation, the image being visible through the card substrate.

19. The credential product of claim 18, wherein the imageable layer comprises a material configured to change from a first level of opacity to a second level of opacity upon exposure to laser radiation.

20. The credential product of claim 19, wherein the portion of the imageable layer that forms the image changes from the first level of opacity to the second level of opacity upon exposure to laser radiation.
