A method (300) is disclosed of calibrating a printing device (110). The method (300) starts by printing (310) a calibration chart (800) comprising a plurality of machine readable marks (920 and 925) and at least one calibration area (820). The machine readable marks (920 and 925) are disposed on different sides of the calibration area (820). Each machine readable mark (920 and 925) independently identifies a type of the calibration area (820). The printed calibration chart is next imaged (330). Finally, the calibration area (820) is utilized to calibrate the printing device (110) in accordance with the identity of the type of calibration area (820).
