Abstract
A system for calibrating a digital scanner utilizes a calibration strip having reference information printed thereon and a machine readable encoded tag having characteristic values corresponding to the calibration strip reference information encoded thereon. A scanning system scans the calibration strip and the machine readable encoded tag to generate image data corresponding to scanned-in reference information and data corresponding to scanned-in characteristic values of the reference information. The correction values are then derived from the generated image data and the decoded characteristic values that accurately describe the desired image data.
