Abstract: A method of scanning a target image and inhibiting backtrack artifacts from the scanned image comprises the steps of initiating a scan on a flat bed scanner, the flat bed scanner comprising at least a scanbar, a memory buffer and a motion control pattern comprised of a plurality of spaced elements, each element having an angled portion with respect to the motion of the scanbar; acquiring scan data comprising a motion control pattern data and an image data with said scanbar; storing the previously acquired scan data in a memory buffer; querying whether the memory buffer reaches a preselected full threshold; acquiring a last valid scan data; stopping and backtracking the scanbar when the memory buffer preselected full threshold is met; and, inhibiting backtrack artifacts by one of a first real-time position analysis or a post-processing analysis.
