ABSTRACT:
An ink jet recording method which can simply realize a plurality of resolutions in a single printer without varying the amount of ink per droplet is disclosed. An ink jet recording method comprises the steps of: selecting a recording medium; changing an image resolution depending on the selected recording medium; and ejecting ink droplets onto the recording medium to form ink dots thereon, wherein the amount of ink of the droplet is constant when the resolution is changed, and wherein the image resolution is changed so that ink penetrability or ink repellency of the recording medium makes the diameters of the ink dots on the recording medium fall in the range of from 100 to 160% of diagonal dot pitch of the resolution.
