1. A copy restrictive medium comprising:
- a support layer;
at least one light sensitive image-forming layer coated on said support layer; and
a pattern of visually undetectable microdots positioned between said support layer and said at least one image-forming layer;
wherein said microdots are detectable by opto-electronic means which are capable of deactivating a printing device.

Abstract
A media for restricting the copying of a document utilizing one or more microdots that are embedded in said document for providing a non-visual, but machine detectable mark or marks. The detected means for detecting the presence of one or more microdots in said document inhibits a copy machine from copying the document.
