Zusammenfassung:	A printing apparatus calibration method is disclosed. The method includes printing, from each of a plurality of dies of a print head, an image in a first color according to a calibration pattern and an image in a second color according to the calibration pattern onto a printable substrate, the calibration pattern including a plurality of patches having a plurality of different densities. The method may include scanning an image formed on a printable substrate using a scanning unit to generate scanned image data, in which an image in a first color is scanned by a first scanning module of the scanning unit and an image in a second color is scanned by a second scanning module of the scanning unit. The method may include analyzing, using a processing device, the scanned image data to identify any difference between print densities of corresponding patches in different images of the same color. The method may include performing a calibration based on the analysis. A printing apparatus and a machine readable medium
