Abstract
A print medium quality adjustment system includes an inspection watermark medium output devicehaving an inspection watermark signal generation unitthat generates at least one inspection watermark signal, generates a watermark signal image by disposing the inspection watermark signal(s) in an arbitrary arrangement, and generates inspection training datahaving digitally recorded therein the inspection watermark signal(s). An inspection medium output unitprints the inspection watermark image onto a medium. A watermark quality inspection devicehas an output unitthat scans the printed medium, a signal detection unitthat extracts embedded watermark information, and a print quality judgment unitthat judges the watermark quality by comparing the extracted watermark information with the inspection training data. Based upon the quality judgment results, a print adjustment valueis generated to be used to improve the print quality.
