Claim of US Patent No. 10,992,840

1. A method comprising:performing a print session in which a printer prints multiple patches on a substrate, the printer using different powers or different intensities for at least two different patches;
performing an imaging session in which image data of the at least two different patches are acquired;
identifying printed elements on each of the at least two different patches;
performing a stacking operation on the at least two printed elements; and
determining calibration data for or print quality data of the printer on the basis of the image data of the at least two different patches.
