ABSTRACT:
A retro-reflective vision control panel which includes an opaque sheet material coated with retro-reflective light reflecting particles and a dark opaque color on the reverse side thereof, and an image formed over top the retro-reflective particles using colored light permeable translucent inks or films to form an image thereon. The opaque sheet and image have a plurality of perforations spaced thereover such that when the light level on the image side of said panel is slightly less than, equal to, or greater than that on the other side, an observer on the image side clearly sees the image while an observer on the other side sees through the panel without seeing any trace whatsoever of the image or design.
