Abstract:
An ink jet recording method for recording a color image by executing record scans by reciprocally moving recording means, on which a plurality of recording element arrays for ejecting inks of different colors are arranged, relative to a recording medium in an alignment direction of said plurality of recording element arrays, each of the plurality of recording element arrays including a plurality of recording element groups, said method comprising the steps of:performing a first record scan of the reciprocal scans to record thinned images of a plurality of colors including a specific color on a predetermined area of the recording medium by using predetermined recording element groups;performing relative movement between the recording means and the recording medium, after the first record scan, in a direction different from the alignment direction; andperforming a second record scan of the reciprocal scans in a direction opposite to that of the first record scan to record a thinned image of only the specific color recorded in the first record scan, on the predetermined area by using a recording element group different from the predetermined recording element groups used in the first record scan;performing a third record scan of the reciprocal scans to record thinned images of a plurality of colors including the specific color on the predetermined area of the recording medium by using recording element groups different from those used in the first and second record scans, said thinned images recorded in the first record scan and said thinned images recorded in the third record scan having a mutually complementary relationship;performing relative movement between the recording means and the recording medium, after the third record scan, in a direction different from the alignment direction; andperforming a forth record scan of the reciprocal scans in a direction opposite to that of the third record scan to record a thinned image of only the specific color recorded in the third record scan, on the predetermined area by using a recording element group different from the recording element groups used in the first, second and third record scans.
