<p>PROBLEM TO BE SOLVED: To provide an inkjet printer capable of reducing the deterioration of printing quality due to ejection order of ink while avoiding the deterioration of productivity of printed matter.SOLUTION: An inkjet printer 1 includes a first head unit 3A and a second head unit 3B which are arranged in parallel along a carriage direction of sheet paper. The first head unit 3A and the second head unit 3B respectively have four nozzle arrays which are arranged in parallel along the carriage direction of sheet paper and respectively eject ink of black, cyan, magenta and yellow from nozzles. A control part 7 determines ejection order of ink of each color in accordance with a print color of color region of red (R), green (G) and blue (B) of secondary color, in accordance with ejection order determination conditions. Therein, the control part 7 performs control so as to selectively eject the ink of each color for each pixel from the first and second head units 3A, 3B based on the determined ejection order.</p> |
