Claim Text:
1. A print apparatus comprising: a print head provided with nozzles that are configured to eject an ink onto a printing substrate, the print head being configured to record dots onto the printing substrate in accordance with movement of at least one of the print head and the printing substrate; a memory storing at least a first group and a second group each of which includes dither masks according to ejected amount of ink, the dither masks of the first group being different from the dither masks of the second group in that a proportion at which dots are formed adjacent to one another relative to the ejected amount of the ink is different; and a print control unit configured to perform a control for ejecting droplets of the ink from the nozzles in a first print mode and a second print mode, the number of the droplets per unit time in the first print mode being lower than the number of the droplets per unit time in the second print mode, the print control unit being configured to determine in which of the first and second modes the ejecting is controlled, in response to determining that the ejecting is controlled in the second print mode, the print control unit being configured to determine what range the ejected amount of the ink is within, configured to select a dither mask of the first group when determining the ejected amount of the ink is within a first range to perform the control for the ejecting, and configured to select a dither mask of the second group when determining the ejected amount of the ink is within a second range greater than the first range to perform the control for the ejecting.
