Zusammenfassung:	A method of document rehabilitation typically includes providing an original document having a set of desirable markings that are substantially achromatic, and a set of undesirable markings, and generating an image file that includes color data corresponding to the original document. A transform filter may be applied to the image file so that the color data for each undesirable marking is mapped to a non-reproduced color, and the color data for each desirable marking is unchanged.
