Abstract:
An image processing method processes image data to be output to an image forming apparatus that is capable of making a two-way recording to form an image on a recording medium by recording in a forward path and a return path of a scan by an ink-jet recording head. The image processing method includes a halftone process that is based on an inclined line-group keytone and maintains keytone continuity, including a dither process in which the inclined line-group keytone appears at a stage where the recording in the forward path is made.
