Abstract
A security, information document for providing information to a reader from an information source organization includes a document substrate having a first area in which a half-tone warning image is printed, indicating that a copy of the document is an unauthorized document. A half-tone background image is printed in a second area on the substrate, with the second area surrounding the first area. A camouflage image extends over the document substrate for confusing the eye of an observer such that the warning image is not readily observed. One of the half-tone warning image and the half-tone background image is printed with a half-tone screen of such a line spacing that it is not readily reproducible by a copier. The camouflage image may contain an identification of the source of the information.
