ABSTRACT:
A printed image, suitable for creating an illusion of depth in the perception of a viewer of the image, comprises a multilayer transparent laminate structure having a back surface and a viewing front surface. A number of the layers in the laminate structure each has a portion of the perceived image printed upon at least one surface of the layer front and back surfaces. That portion of the image perceived to be most distant from the viewer is located upon a printed layer which is furthest from the viewing front surface of the laminate structure, and that portion of the image percieved to be most proximate to the viewer is located upon a printed layer closest to the viewing front surface. The portions of the image perceived to be at varying distances therebetween are located upon intermediate printed layers in a sequence which corresponds to the perceived varying distances of the intermediate image portions. At least a majority of the image portions are dissimilar parts of the perceived image. Generally, the laminate structure contains a plurality of layers each having a portion of the perceived image printed upon the layer front surface, but a layer may have a part of the image on its front surface and another part on its back surface. Depth perception may be further enhanced by the insertion of transparent unprinted panels between printed layers.
