Abstract
A media for restricting the copying of a color-reversal document utilizing one or more microdots that are embedded in the color-reversal document for providing a non-visual, but machine detectable signal. By detecting the presence of one or more microdots in the color-reversal document, a copy machine is controllably prevented from copying the color-reversal document.
