摘要： When multi-pass printing is performed, the dot overlap rate (ratio of the number of dots that overlap and are to be printed in the same pixel area by the plurality of relative movements with respect to the total number of dots to be printed in a pixel area by the plurality of relative movements) in pixel areas having medium-density where density unevenness caused by density fluctuation easily stands out is made higher than the dot overlap rate in pixel areas having low-density and pixel areas having high-density. By doing so density unevenness caused by density fluctuation is suppressed. In addition, the dot overlap rate in pixel areas having low-density and pixel areas having high-density is low, so it is possible to reduce graininess in low-density areas and suppress a decrease in density in high-density areas.

摘要： In image processing, it is possible to suppress density fluctuation and keep graininess low as well as obtain a good balance of the processing load. More specifically, when dividing multi-valued data and generating two-pass multi-pass printing data, divided multi-valued data that is common to the two passes is generated in addition to the divided multi-valued data for each of the two passes. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each pass. Furthermore, when generating quantized data, a process of generating common data by the aforementioned data division, or a process of performing quantization first without dividing the multi-valued data and then dividing the quantized 2-pass data is selectively performed according to the printing position on printing medium.

摘要： In an overlapping head including a plurality of recording head chips overlapped to each other, a color shift can occur between a color recorded by an overlapping region and a color recorded by a non-overlapping region, which cannot be corrected by a density correction using head shading or the like. To correct such a color shift, a test pattern is recorded by the overlapping region and the non-overlapping region and colors of the recorded test pattern are measured. Color correction data to be used in correction of colors of an image to be recorded is generated based on a result of the measurement of the colors.

摘要： When a gradation mask is used to distribute image data to be recorded by overlapping portions in an overlapping head, color unevenness is generated in an image recorded by the overlapping portions due to a displacement in impact positions caused by an assembly error. As a result, accurate colorimetric measurement of patches recorded by the overlapping portion cannot be performed. To solve such a problem, a distribution ratio by which the image data is distributed to the overlapping portions is set to be approximately constant when recording a test pattern for performing color correction, as compared to when normally recording the image.

摘要： A high quality gray scale (monochrome) image in which influences of “recorded color deviation” and “color transition” are suppressed is formed even in the case of a slightly uneven discharge amount. When a gray scale (monochrome) mode is set, in the entire range of a luminance signal, density signals corresponding to achromatic dots and small chromatic dots respectively are generated based on the luminance signal so that the density signal corresponding to the achromatic dots has a greater value than that of the density signal corresponding to the small chromatic dots. Accordingly, even a slight “recorded color deviation” that occurs when the achromatic dots are recorded can be corrected by the small chromatic dots having a hue opposite to the direction of color deviation, and a high quality gray scale image in which influences of “recorded color deviation” and “color transition” are suppressed can be formed.
