摘要： A paper feed operation is performed by a width less than one pixel (½) in addition to an integer multiple number of pixels (n/2) with respect to a basic number of pixels inherent to an ink jet recording apparatus having a multi nozzle head having n nozzles. When a plurality of pixel recording operations are performed for a single pixel region, ink dots land within a distance less than one pixel unit (½). Thus, a variation in ink surface density on a recording sheet in an overlapping print operation is reduced, thereby efficiently increasing the image density, and preventing blurring by promoting absorption and evaporation of an ink to and from a paper sheet.

摘要： 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 in a plurality 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.
