Abstract:
A method of recording an image by forming ink dots on a print medium during main scans, comprising the steps of:(a) generating dot data from image data indicative of the image, the dot data representing a state of dot formation at each pixel; (b) identifying a transverse contour line of a specific type image area represented by the dot data, the transverse contour line being parallel to a main scan direction, the specific type image are being composed of pixels at which specific tones are recorded by forming ink dots; (c) adjusting the dot data so as to regularly reduce amounts of an ink for forming ink dots on the identified transverse contour line; and (d) recording tones of pixels on the print medium by forming ink dots in response to the adjusted dot data; wherein the step (d) includes the step of: (e) recording the tones of pixels such that adjacent pixels in the main scan direction are recorded during different main scans, respectively.
