Abstract:
1. A recording apparatus for effecting recording on a recording material using a recording head including a plurality of nozzles usable for the recording, the nozzles being arranged in a first direction, said recording apparatus comprising: moving means for moving said recording head in a second direction crossing with the first direction; feeding means for feeding the recording material in the first direction by a distance corresponding to a width of one of a plurality of nozzle blocks into which said plurality of nozzles are divided, between movements of said recording; and control means executing the recording of said recording head during the movement of said recording head in accordance with image data corresponding to said nozzles and a mask pattern for masking the image data; wherein (i) said mask pattern includes at least a first pattern portion for masking the image data corresponding to each nozzle of a first nozzle block included in said plurality of nozzle blocks, and a second pattern portion for masking the image data corresponding to each nozzle of a second nozzle block adjacent said first nozzle block, (ii) a ratio of recording permission pixels in each pixel row extending in the second direction in a non-boundary area of said first pattern portion is substantially a first value, and a ratio of recording permission pixels in each pixel row extending in the second direction in a non-boundary area of said second pattern portion is substantially a second value which is different from a first value, (iii) in a boundary area including a boundary between said first pattern portion and said second pattern portion, a ratio of recording permission pixels in each pixel row extending in the second direction is between the first value and the second value, and the ratios of the recording permission pixels in a pixel line extending in the first direction are different depending on a position with respect to the second direction.
