Abstract: When an image is recorded using an ink of a basic color and an ink of a specific color, if an amount of ink applied to a recording medium exceeds an amount receivable by the recording medium, the ink overflows and image quality deteriorates. At this time, ink overflowing can be prevented by reducing an application amount of ink, but color balance may vary. By preferentially reducing an application amount of the ink of the specific color among inks of a plurality of colors that are to be applied to a recording medium, a change in the color balance is suppressed and the ink overflowing is prevented.
