Abstract
A method for encoding data in a monochrome media utilizing the capability of the media for grayscale resolution. A document is processed to provide an image in electronic format, in which each pixel has an assigned data value with a given bit depth. A mapping operation is performed for generating a monochrome data word (), preferably having a reduced bit depth. The monochrome data word () can be used to encode multiple data fields (). A printer () then produces a preserved document record () in which the appropriate monochrome data word () determines the grayscale value for each pixel.
