Abstract
An original document includes alphanumeric characters defined by an overprinted reflective layer formed on a complex patterned region, and having graphic or font size, shape and type coordinated to the particular patterns in the patterned region. The coordination of the overprinted reflective layer with the patterned region is such that if the document is electronically scanned or duplicated by xerographic photocopying, the pattern will at least partially obscure the alphanumeric characters so that they can only be read with difficulty, thereby camouflaging the text.
Claims15
A counterfeit-resistant document, comprising:
- a substrate having a first printable surface;
- a camouflage background pattern printed on at least a portion of said first printable surface of said substrate;
- and
- an image on said first printable surface, said image overprinted on said camouflage background pattern, said image having different reflective characteristics than said camouflage background pattern, wherein said camouflage background pattern obscures said image at viewing angles employed by photocopy devices.
A method of printing a counterfeit-resistant image on a substrate surface, comprising the steps of:
- printing a camouflage background pattern on a portion of a first printable surface of a substrate;
- and
- overprinting an image on said camouflage background pattern, said image having different reflective characteristics than said camouflage background pattern, said image may be printed on said camouflage background pattern in one of a variety of fonts or styles slected to correspond to said camouflage background pattern, the dimensions of said image are coordinated with said camouflage background pattern so that when said substrate is electronically scanned, the scanned image of said image is at least partially obscured by the scanned image of said camouflage background pattern.
