1. A moiré-based auto-stereoscopic enhanced rendered image, comprising: image data segmented into a first partition and a second partition for enhanced rendering; a substantially transparent substrate having a first side and a second side; a first side applied marking material having a first halftone periodic structure at a first frequency, as applied to and placed on the first side of the substantially transparent substrate; and, a second side applied marking material for rendering the image data as applied to the second side of the substantially transparent substrate, further comprising for the image data first partition a second periodic halftone structure at a second frequency, that second frequency being related to but some delta away from the first frequency, and for the image data second partition, a third periodic halftone structure at a third frequency, that third frequency being related to but some delta away from the first frequency, such that when the rendered substantially transparent substrate is viewed from either side a moiré-based auto-stereoscopic enhanced rendered image is evident.
