Abstract: A high precision printing method taking into consideration the variance in the thickness of a printing target. An ink-jet printing method, including: (i) measuring a distance between a printing target and at least one nozzle; (ii) measuring a flying speed and a flying angle of an ink(a) discharged from the at least one nozzle; (iii) printing a test substrate with an ink to identify a location on which an ink(b) is spotted, and calculating a thickness-related displacement that is a displacement from the location on which the ink is spotted, based on a thickness difference between the printing target and the test substrate from results obtained in Step (i), and the flying speed and the flying angle of the ink(a) obtained in Step (ii); and (iv) discharging an ink(c) from the at least one nozzle to achieve actual printing of the printing target with the ink(c) while correcting the thickness-related displacement.
