PROBLEM TO BE SOLVED: To reduce clogging of a nozzle to realize improvement of printing quality and printing speed.SOLUTION: An inkjet device includes: a line type print head in which a nozzle row direction crosses a conveying direction, a plurality of nozzles exists, and the nozzles discharging the same ink are arranged in the nozzle row direction; and a printing control unit for generating printing data by applying a dither mask to image data expressed by a group of pixels to realize printing by discharging the ink to inkjet paper from the nozzles of the print head on the basis of the printing data. The inkjet paper is moved in the conveying direction, and the printing control unit performs change processing for changing a setting of a start position for starting application of the dither mask to the image data. |
