Abstract
A method for detecting gloss non-uniformities on printed documents is provided. The method includes printing a test pattern using a print engine, the test pattern having gloss; directing one or more light beams, using an illuminator, onto the test pattern to produce at least generally specular reflectance; scanning the test pattern, using a linear array sensor, to obtain image data, the image data corresponding to the generally specular reflectance from the test pattern; and enhancing contrast of the image data to facilitate detection of image quality non-uniformities in the gloss in the test pattern.
