Abstract: Provided is a dither pattern generation method so that a dot arrangement having excellent dispersibility can be obtained in low-gradation areas for single colors and for mixed colors. The dither pattern generation method generates dot patterns for low-gradation areas having threshold values 1 to S so that high dispersibility is obtained in a cyan dot pattern and a magenta dot pattern, and so that in a combined dot pattern made by combining these dot patterns there are no overlapping pixels. The dither pattern generation method then sets threshold values for a cyan dither pattern and a magenta dither pattern based on these generated dot patterns.

Abstract: A method for printing an image with colour pixels is disclosed. This method optimizes the print quality for a selected level of ink usage by maximizing a dot-off-dot strategy and separating between direct binary search dot patterns for a number of selected colorants in a printer comprising black colorant. Ink usage is controlled by determining the fraction of coinciding printer colorants that may be substituted by black colorant. The perceived error between the image pixels and the image dot pattern is minimized according to a human visual system model that excludes non-homogeneous patterns that affect the quality of the halftone textures. Dots for other colorants are processed independently and added to the obtained halftone dot pattern for the selected colorants.

Abstract: According to an aspect of the invention, an image forming apparatus includes an image correction unit and a determination unit. The image correction unit inserts a new pixel between pixels forming image data with a plurality of pixels printed using a plurality of print color materials arranged in a main scanning direction in order to correct the image width in the main scanning direction.
