Patent number: 9039157Abstract: There are provided an image processing apparatus and an image processing method which can shorten a drying time of inks in an edge region of an image, and can form a sharp image without bleeding of the ink applied onto the edge region into a blank paper. The image processing method generates applying data for forming an image on a print medium by a relative scan between print heads for ejecting a first ink and a second ink having the same color with the first ink and lower in surface tension than the first ink, and the print medium. The image processing method generates first data for applying the first ink to a predetermined region that is adjacent to an edge region of the image and that is included in an inside region inward of the edge region, and generates second data for applying the second ink to the edge region.Type: GrantFiled: January 16, 2013Date of Patent: May 26, 2015Assignee: CANON KABUSHIKI KAISHAInventors: Takao Ogata, Noboru Kunimine
