INK JET RECORDING METHOD AND INK JET RECORDING DEVICE

摘要

In high-speed printing by a recording head having nozzles arranged with a high density, it is possible to reduce the turbulence generated between the recording head and a recording medium, thereby forming a high-quality image. For this, recording is successively performed according to thinned image data thinned by a mask pattern M into the same recording area of the recording medium by each of the nozzle strings arranged in the recording head (17), thereby completing an image with a multi-pass. Here, a plurality of image data to be recorded in the same recording area where nozzle strings (17A to 17D) pass in one pass are alternately thinned with different thinning ratios, i.e., a high and a low thinning ratio in the nozzle arrangement direction.
