Abstract (en)
[origin: EP3466690A1] Provided are an inkjet printing apparatus and an inkjet printing apparatus control method capable of limiting the reduction in image quality of an image that is printed with an intervening interruption. The inkjet printing apparatus is provided with: a conveyance means for conveying a print medium in the conveyance direction; ink-discharging units provided so that the range of placement of each of multiple printing element rows overlaps with another printing element row in the width direction and is separated therefrom in the conveyance direction; and a control means for causing the ink-discharging units to perform image printing operations in which the multiple printing elements discharge ink to print an image on the print medium. In the image printing operation, at each position in the conveyance direction and for each position of the width direction in the areas of printing element row overlap, an ink-discharging operation is performed by at least one of the printing elements belonging to the two or more printing element rows. When the printing of an image is interrupted, the control means causes the ink-discharging units to perform an image printing operation on a partial image, which excludes the portions of the image that are not to be printed due to the interruption.
