Abstract
A print unit includes a reactive liquid element row in which a plurality of print elements are arrayed in a first direction, a first element row in which a plurality of print elements are arrayed in the first direction, and a second element row in which a plurality of print elements are arrayed in the first direction. The reactive liquid element row, the first element row, and the second element row are arrayed in this order in a second direction perpendicular to the first direction. A scan unit scans the print unit in the second direction. A print control unit controls a print operation by the print unit such that a ratio of the number of pixels permitted to eject the second ink to the number of pixels in a predetermined region on the print medium does not exceed a threshold.
