Abstract:
1. A printing method comprising: a plurality of times of a scanning process including scanning with a printhead for ink jet printing and discharging ink to a printing medium from the printhead, characterized in that including differentiating head-facing areas to which the ink is discharged in a state of facing straight toward the printhead from each other in the respective scanning processes, discharging the ink to a non-head-facing area to which the ink is discharged in a state of not facing straight toward the printhead in any of the scanning processes without facing the non-head-facing area straight toward the printhead also in other one or more scanning processes, and adjusting the amount of the ink to be discharged in the non-head-facing area in at least one of the scanning processes so that the total film thickness of the ink coating formed in the non-head-facing area becomes a predetermined film thickness, wherein when the ink is discharged to one point in the non-head-facing area in the n times (n is integers of 2 or larger) of the scanning process, an amount D (where D 0 denotes the amount of the ink to be discharged to one point in the head-facing area in the respective scanning processes) by using a coefficient of adjustment k i set so as to satisfy the following expression (1) (where θ
