Abstract: Nozzles in a print head are arrayed in a density of 600 dpi. Moreover, a dither matrix has a size of 16 pixels×16 pixels in 600 dpi. The dither matrix is repeatedly used. In the meantime, each of rectangles represents an HS processing unit. WHS=3 pixels. As a consequence, the relationship of a least common multiple below is established in a nozzle array direction: 3×WD=16×WHS. In this case, the cycle of interference unevenness can be prolonged to the least common multiple between WD and WHS, that is, 48 pixels (3WD). In this manner, the size of the dither matrix is not an integral multiple of the HS processing unit width, so that the cycle of interference unevenness can be prolonged more than the size of the dither matrix. Thus, the interference unevenness can be hardly recognized.

Abstract translation: 打印头中的喷嘴以600dpi的密度排列。 此外，抖动矩阵在600dpi中具有16像素×16像素的大小。 重复使用抖动矩阵。 同时，每个矩形表示HS处理单元。 WHS = 3像素。 因此，在喷嘴排列方向上建立以下最小公倍数的关系：3×WD = 16×WHS。 在这种情况下，干扰不均匀的周期可以延长到WD和WHS之间的最小公倍数，即48像素（3WD）。 以这种方式，抖动矩阵的大小不是HS处理单元宽度的整数倍，使得干涉不均匀的周期可以比抖动矩阵的大小更长。 因此，难以识别干涉不均匀性。

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: Provided are an image processing apparatus and an image processing method capable of reducing color unevenness due to variations in ejection characteristics among a plurality of nozzles when printing an image using a plurality of inks. To that end, a first image which is made up a color with noticeable color unevenness and similar colors is printed onto a print medium. The user then specifies a color and a nozzle position where color unevenness has occurred. On the basis of these results, parameters are set for a correction table referenced by an MCS processor. In so doing, it becomes possible to address the factor causing the color unevenness, and mitigate the effects of color unevenness in a focused way without incurring increases in processor load, memory requirements, or processing time as compared to the case of calibrating all lattice points.

Abstract: An image processing apparatus for generating dot data to form an image by forming dots on a recording medium includes a receiving unit, a first, second, and third generating unit, and a correcting unit. The receiving unit receives first and second image data included in image data. The first generating unit generates, per the first image data, first ink color data representing a multi-valued signal value corresponding to an ink color. The second generating unit generates, per the second image data, second ink color data representing a multi-valued signal value corresponding to an ink color. The correcting unit corrects the signal value represented by the generated first and second ink color data. The third generating unit generates, per the first and second ink color data of which the signal values have been corrected, the dot data representing existence of formation of dots to form an image.
