Abstract:
1. An inkjet printing apparatus, comprising: a printing unit configured to cause a print head to scan a print medium a plurality of times, the print head being able to eject a plurality of types of inks and treatment liquid to make contact with the inks, thereby forming an image based on image data; and a control unit configured to decide an application volume of the treatment liquid to a predetermined unit region of the print medium on the basis of the image data and divide the application volume to the plurality of times of scans, wherein in case the application volume to the unit region formed by an ink with a larger contact angle relative to the treatment liquid is the same as the application volume to the unit region formed by an ink with a smaller contact angle relative to the treatment liquid, the control unit controls each of the application volume divided to the plurality of times of scans so that the application volume to the ink with a larger contact angle is larger than the application volume to the ink with a smaller contact angle at the time of at least one scan.
