Curing can be carried out with high sensitivity in a low density area where the droplet ejection density is relatively low, and gradation reproduction can be performed well in a low density area. When colored ink droplets ejected by a first ejection head have a droplet ejection amount of 10 g / m 2 or less, droplets of transparent ink deposited by a second ejection head 12 are subjected to the landing of colored ink. In addition to superimposing on the top, the amount of transparent ink deposited upon droplet ejection is controlled in accordance with the amount of colored ink deposited. [Selection] Figure 4 |
