Abstract:
An image printing apparatus comprising:storage means for storing absorbing speed information representing a speed at which a recording medium used for a printing process absorbs an ink used for the printing process; and control means for controlling an ink head so as to perform a first dot recording which records a plurality of first dots on the recording medium by a pitch of an ink ejection opening of the ink head, and for moving the ink head relative to the recording medium and controlling the ink head so as to perform a second dot recording which records a plurality of second dots between the plurality of first dots recorded by the first dot recording, in accordance with a print interval time determined to meet the relationship: Ux<2.04Ã—tâˆ’0.87(where Ux>0) between the speed at which the recording medium absorbs the ink ejected from the ink head and the print interval time between the first dot recording and the second dot recording when the speed is defined as t (picoliters per millisecond) and when the print interval time is defined as Ux (seconds) based on the absorption speed information stored in the storage means.
