ABSTRACT:
A system for restricting the copying of a color-reversal document having one or more microdots embedded in the color-reversal document. The system of detecting the presence of one or more of the embedded microdots and controllably disabling a copy machine to prevent it from copying the color-reversal document when at least one microdot is detected.
