METHOD AND APPARATUS FOR MATCHING GLOSS LEVELS OF PRINTED AREA AND NON-PRINTED AREA OF MEDIUM SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for matching the gloss level of a printed area on a medium substrate surface to the gloss level of a non-printed area on the medium substrate surface.

SOLUTION: Optical reflection intensity is measured in the printed area and non-printed area on the surface of the medium substrate 14 and read by a gloss sensing device 20 which communicates the intensity to a printer controller 25. The printer controller compares reflection intensity values of the two areas with each other to decide whether they are substantially equivalent. When not, the printer controller instructs alteration in printing parameters, e.g., the temperature and/or pressure of a fuser roller 12 for establishment of equivalence.
