Beschreibung
Zusammenfassung:	A multicolor thermal printer comprising a controller, a thermal printhead, multicolor thermal paper, a monochrome lightness sensor, and a calibration subsystem is described. The calibration subsystem prints a calibration target that is scanned by the monochrome lightness sensor to determine if color crosstalk is present. If color crosstalk is present, the calibration subsystem decreases the contone range of affected colors and saves the new calibration settings.
