TLDR
In this article, the arrangement of ejection openings is determined so that between the last scanning for completing the black image and the first scanning for printing of the color image, scanning with no performing printing exists.Abstract:
A high-quality image is printed with reduced bleeding in colors that may appear at a boundary between a black image and a color image. A head for ejecting black ink and a head for ejecting color ink perform three times of scanning while feeding is carried out therebetween for moving the printing medium by four pitches of ejection openings arranged on the heads, different ejection openings are caused to correspond to a scanning area, which corresponds to the four pitches, and multi-pass printing is performed to complete printing on the area. The black head completes printing of the black image, and then, the color head completes printing of the color image adjacent to the black image. The arrangement of ejection openings is determined so that between last scanning for completing printing of the black image and the first scanning for printing of the color image, scanning with no performing printing exists.read more
