Abstract:
An ink jet recording apparatus for recording an image on a recording medium, wherein a first discharging orifice array arranging a plurality of discharging orifices for discharging a first ink and a second discharging orifice array arranging a plurality of discharging orifices for discharging a second ink are disposed in parallel in a main-scanning direction different from the arranging direction of the orifice arrays, and said first discharging orifice array, said second discharging orifice array, and the recording medium are relatively moved in the arranging direction of said discharging orifices for each main-scanning of said first discharging orifice array and said second discharging orifice array in the main-scanning direction, said apparatus comprising:control means for controlling in such a manner that when an area where a main-scanning region of the first discharging orifice array does not overlap with a main-scanning region of the second discharging orifice array is a first area and an overlapping area is a second area, in the case where both of first image data to be recorded by the first discharging orifice array and second image data to be recorded by the second discharging orifice array exist in the first area, recording for the first area by the first discharging orifice array is not performed in the main-scanning but recording is performed by the first and second discharging orifice arrays in the main-scanning after the relative movement is performed up to a position where both the first and second image data can be recorded in the first area, and in the case where the first image data to be recorded by the first discharging orifice array exists in the first area and no second image data to be recorded by the second discharging orifice array exists, in the main-scanning, recording is performed in the first area by the first discharging orifice array.
