摘要： The present invention prints a plurality of ejection characteristics detection patterns with different print duties. Each of the patterns is divided into areas with a certain number of pixels, and each area is read with a plurality of different read colors. Based on the read values by the read color for each area, evaluation values by the read color that indicates ejection variation volume that is the difference between ink ejection volume to each area and standard ink ejection volume are set. A weighted average is obtained by applying the weight determined by reading accuracy of a reading unit to evaluation values by color for each area with different print duties formed by the same nozzle. The ejection characteristics of a nozzle that prints each of the areas are evaluated using the weighted average value.

摘要： An image processor, a printing apparatus, and an image processing method are provided that can reduce, when a plurality of types of inks are used to print an image, the color unevenness that is caused by the variation of ejecting characteristics among a pluralities of nozzles. To realize this, for a color formed by overlapping at least two colors of inks, parameters are prepared that are determined so as to reduce the color difference in the printing medium due to the variation of the ejecting characteristic among the respective pluralities of nozzles. During printing, the parameters are used to correct the first color signal owned by the individual pixels to the second color signal.

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.
