Abstract
The invention claimed is a method for elimination of a reverse side reflection, or ghosting effect, resulting from a dual sided media being scanned utilizing a standard document scanner or analogous hardware wherein the reverse side reflection typically results in a defect on the scanned image. The inventive method is unique to the prior art in that it incorporates backing which impedes reflection of the reverse side of a scanned page that typically manifests as an unwanted artifact on the resultant scanned image. The inventive method further eliminates, in the case of sheet fed or duplex scanners, the requirement for alternating the scanner's light source to create artificial black and white reference for calibration of the scanner.
