Abstract: A plurality of recording heads for ejecting inks in different colors are aligned, and are reciprocally moved in the alignment direction, and an image is recorded by performing main scans in both the forward and backward paths of the reciprocal movement, and performing a sub-scan after each main scan. An area recordable in a single main scan is thinned out according to thinning arrangements having a complementary relationship therebetween, and thinned-out images are recorded in a plurality of main scans. During this interval, the sub-scan is performed in a direction opposite to be no normal sub-scan direction at a predetermined period.

Abstract: The mounting positions of a plurality of recording heads (1Y, 1M, 1C, 1K) are set to be variable with respect to a paper feed direction, so that a post-ejection recording head (1Y) is mounted at the downstream side in the paper feed direction as compared to a pre-ejection recording head, thereby preventing generation of banding in color ink jet recording, and improving image quality.

Abstract: When image formation on an image area corresponding to a recording section of a recording head is completed by executing a plurality of number of times of record scans of the recording head using a plurality of complementary thin-out patterns, scan intervals are gradually increased before execution of pre-ejection and scan intervals are gradually decreased after execution of pre-ejection, so that a variation in scan intervals of the plurality of times of record scans for a single image area is limited to fall within a predetermined time range.

Abstract: An ink jet recording apparatus for performing recording using a recording head for ejecting an ink from a plurality of ejection orifices, includes a print control unit for performing a print operation while switching a print mode between a thin multi-pass print mode for sequentially recording divided recording data in a plurality of number of times of relative scan operations of the recording head with respect to a single recording area, and a 1-pass print mode for recording all recording data in a single relative scan operation of the recording head, and an eject quantity control unit for controlling the eject quantity of the ink ejected from the recording head so that a total ink quantity on the recording area in the thin multi-pass print mode is larger than a total ink quantity in the 1-pass print mode.

Abstract: A recording head having a plurality of recording elements can operate in a first recording mode for recording a desired image by performing a single scan operation on a predetermined region on a recording medium, and a second recording mode for recording a desired image by recording a thin image a plurality of number of times by performing a plurality of number of times of scan operations on the predetermined region. The scan speed in the second recording mode is set to be higher than that in the first recording mode. For example, when the scan speed in the second recording mode is N times that in the first recording mode, the driving operation of the plurality of recording elements is controlled to obtain a dot pattern in which the minimum dot distance in the scan direction in the second recording mode is N times or more that in the first recording mode. Image quality can be improved without decreasing the throughput.
