Abstract
An imaging device and calibration method therefore forms a plurality of hard images upon media using user-defined image data. An optical characteristic of at least a portion of the hard images is sensed at a plurality of different spatial locations of the hard images. The sensed optical characteristic is compared with the user-defined image data, and the imaging device is calibrated using the sensed optical characteristic.
