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.
