Abstract
The present application is directed to a method of creating a dual appearance comprising providing a substrate. The dual appearance is further created by providing an illumination source proximate to the second major surface of the substrate. A reflective image is provided on the first major surface of the substrate opposite the illumination source. A transmitted image is provided on the second major surface of the substrate between the substrate and the illumination source. Generally, the reflective image is visible with the illumination source off and the transmitted image is visible with the illumination source on.
