Abstract
Disclosed herein, among other things, are method and apparatus for calibrating imaging equipment. According to one embodiment of a method, a calibration deck of timing sheets is prepared. The calibration deck includes a sheet with a series of reference marks that help determine the amount of skew, a sheet with objective scoring bubbles that are all filled in with black ink, a grey scale bubble sheet having a predetermined number of shades between black and white, and a sheet with objective scoring bubbles that are all unfilled, or white. The timing sheets are scanned on a scanner, and results from scanning the calibration deck are compared to an industry standard baseline.
