Abstract
An inkjet printing device uses a print head including a first nozzle array for ink ejection and a second nozzle array for ejection of an image quality improvement liquid (CL), and the device prints an image on a print medium by repeating a print scan. The inkjet printing device includes a first controller for, during a first print scan, allowing nozzles on an upstream side of the first nozzle array in the conveying direction to eject the ink, and a second controller for, during the first print scan, allowing nozzles on an upstream side of the second nozzle array in the conveying direction to eject the liquid (CL) into an ink ejection area. In aaddition, a third controller, during a second print scan after the first print scan, allows nozzles on a downstream side of the second nozzle array in the conveying direction to eject the liquid (CL) into the ink ejection area.
