ABSTRACT:
An image processing method performs processing to generate image data based on input data and output the image data to an image forming device. The image forming device includes a printing head in which first nozzles for ejecting color ink drops are arranged in a symmetrical formation to forward and backward scanning directions and second nozzles for ejecting black or gray ink drops are arranged in an unsymmetrical formation with respect to the first nozzles. The image forming device is adapted to perform a uni-directional printing or a bidirectional printing with the printing head. In the image processing method, a black generation processing to the input data is performed, and when performing the black generation processing, a black-generation start level for the bidirectional printing is delayed to a shadow-side gradation level from a black-generation start level for the uni-directional printing.
