Abstract
In an area to be recorded with a black ink and a color ink superposed, when an area recorded by the same main-scanning and an area recorded by the other main-scanning mixedly exist, band unevenness occurs. It is an object of the present invention to suppress the band unevenness without reducing a recording speed. Therefore, upon certain main-scanning, it is determined whether image data to be recorded with a cyan ink exists in an area C in FIG. 2 or not. When it is determined that the image data exists, recording by a discharging orifice array for black is not performed in the area C in the main-scanning. When it is determined that no image data exists, recording for the area C is performed in the main-scanning by the discharging orifice array for black.
