Abstract: An image data processing device processes image data. The image data processing device includes an image data storing unit, a correction data producing unit, and an image density value addition unit. The image density value is either a first density value that is greater than or equal to a prescribed value or a second density value that is less than the prescribed value. The ink droplet is ejected on the first subject pixel whereas the ink droplet is unejected on the second subject pixel. The correction data producing unit produces correction data including a plurality of correction density values. The image density value addition unit adds the correction density value to the second density value of the corresponding pixel. The correction data producing unit produces a first correction density value and a second correction density value as the correction density value.
