Identification document with printing that creates moving and three dimensional image effects with pulsed illumination
First Claim
Patent Images
1. An identification document comprising:
- document layers, including two or more printed image layers;
the image layers having different ink properties that when illuminated in different illumination bands become detectable in a detection band;
the image layers being arranged relative to each other and depicting an object from different perspectives to collectively create a three dimensional appearance of the object in response to being strobed with illumination in the illumination bands corresponding to the image layers, the printed image layers representing a two dimensional representation of the object when not responding to the illumination in the illumination bands.

Abstract
Identification documents have a three dimensional or moving image effect to enable human verification of their authenticity. These effects are created by printing image layers of invisible inks, such as UV or IR fluorescing inks, each depicting an object in varying position or perspective in an area on the document. When the area is strobed sequentially in different bands corresponding to the different layers, the layers become visible sequentially or simultaneously, creating a moving and/or three dimensional effect.

19. An identification document comprising:
-
document layers, including two or more printed image layers; the image layers having different ink properties that when illuminated in different illumination bands become detectable in a detection band;
the image layers being arranged relative to each other to collectively create a moving image effect when strobed with illumination in the illumination bands corresponding to the image layers;
wherein the image layers depict an object;each image layer depicting a different position of the object, wherein the object appears to move when strobed; and wherein the image layers are interleaved over an area on the document such that when strobed, a viewer sees the different positions of the object and perceives a moving object effect in the area of document, the printed image layers representing a stationary image effect when not responding to the illumination in the illumination bands. - View Dependent Claims (20)

32. A method of verifying an identification document comprising:
-
strobing an area on the document with illumination in different illumination bands, the document including two or more image layers depicting an object; each image layer depicting within the area, a different position or perspective of the object; each of the layers being printed with inks in the area having different illumination bands that cause the object to be detectable in a detection band; detecting a moving image or three dimensional appearance of the object in the detection band caused by the strobing, the printed image layers representing a stationary image effect of the object when the different positions are not responding to the illumination in the illumination bands or a two dimensional representation of the object when the different perspectives are not responding to the illumination in the illumination bands. - View Dependent Claims (33, 34, 35)
