ABSTRACT:
A method of correcting for sensitivity variation of media sensors includes determining a first signal level corresponding to a first calibration media having a first glossiness; determining a second signal level corresponding to a second calibration media having a second glossiness, the second glossiness being greater than the first glossiness; and determining a corrected normalized signal level ratio of an unknown media based on the first signal level of the first calibration media and the second signal level of the second calibration media.
