Abstract
A scanner for copying an image from substrate including a substrate holder for holding the substrate having a reference grid preferably disposed to one side of the substrate. The scanning means, e.g., a CCD array, simultaneously scans the image and the reference grid as the substrate holder is moved relative to the scanning means. The scanner contains software and/or hardware for interpreting the sensed portion of the reference grid as a position. The position is associated with the raw scan line of the image which was sensed at the same time as the sensed portion of the reference grid.
