摘要： The invention decreases the enlargement of memory and processing time for the correction of image data carried out to reduce image deterioration caused by nozzle ejection characteristic variation in an inkjet printing apparatus. Print heads are provided with pluralities of chips that have nozzle arrays formed from a plurality of nozzles. Coupled portions and non-overlap portions are formed on each chip. An image processing apparatus sets input image data, which correspond to nozzle regions that are defined in nozzle arrays along the alignment direction of the nozzles of the print head and that are composed of a plurality of nozzles, as processing blocks. The input image data is processed according to parameters defined for each of those processing blocks. The boundaries of the nozzle regions corresponding to the input image data of the processing blocks are established according to the boundaries of the overlap portions and the non-overlap portions.

摘要： There is provided an image processing method in which in a full line type inkjet printer using a connecting head having an overlap region, even if a conveyance direction of a print medium is more or less inclined, a density change or degradation of graininess is not introduced. Therefore, an image data in a non-overlap region is distributed to a plurality of nozzle arrays such that ink is ejected from all the plurality of the nozzle arrays. On the other hand, a region where a print allowance rate changes in the overlap region is divided into plural regions, and the image data is distributed to the plurality of the nozzle arrays such that these regions are located to be shifted.

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： Printing heads of combinations of four ink colors and seven printing characteristic ranks are previously used to print an image for measurement, and table parameters corresponding to all of the combinations of nozzle ink colors and printing characteristic ranks are obtained on the basis of a measurement result of this image for measurement and stored in a memory. Then, when printing is actually performed in a printer, a primary color image for measurement is printed for each nozzle of a printing head for each of four ink colors. A printing characteristic rank for each nozzle is obtained for each of four ink colors based on a measurement result of this image for measurement, and a table parameter is selected that corresponds to the same combination as the combination of the obtained printing characteristic rank of each nozzle of four ink colors, by referring to the memory.

摘要： When printing an image using a plurality of inks, color unevenness caused by variations in ejection characteristics among nozzles is corrected at suitable timings in accordance with change in the color unevenness over time, and favorable image output without noticeably color unevenness is maintained. For this purpose, parameters are prepared, for colors formed by combinations of at least two colors of ink, the parameters being determined so as to reduce differences in coloration on a print medium caused by individual variations in the ejection characteristics of a plurality of nozzles. When printing, a first color signal included in individual pixels is corrected for a second color signal by using the parameters. Information regarding the ejection volume characteristics of a plurality of nozzles is acquired as appropriate, and by estimating changes in coloration from this information, suitable timings for overwriting such parameters are determined.
