摘要： In the process of correcting a color deviation caused by output characteristic variations among different colorants in a printing apparatus, a method of printing a test pattern allows an appropriate and highly accurate visual detection of the color deviation. More specifically, the test pattern has a plurality of patches printed therein, each of which has placed adjacent to each other a test area to be checked for the color deviation and a reference area serving as a criterion for color deviation and which has the test area and the reference area repeated alternately. If the colors of the two areas look different during the comparison of only one pair of the test area and the reference area, the pattern of the two alternately repeated areas makes the colors of the two areas appear more uniform, alleviates a high color difference sensitivity and thereby enables easy identification of a patch that matches the accuracy of the correction performed according to the color deviation detection.

摘要： In a correction processing that corrects a color deviation caused by output characteristic variations among print heads of a printing apparatus, the printing apparatus prints a test pattern that allows accurate detection of the color deviation by a visual check. More specifically, each of the patches in the test pattern is made up of two areas placed adjacent to each other. One of the two areas (upper area) is used as a test area for detecting the degree of the color deviation. Of the gradation values of C, M and Y, which make up the patch print data, the gradation values of C and M are changed among the patches making up the test pattern. The other area is used as a reference area printed with an achromatic color that represents a reference gradation value for the deviation detection. The gradation values of C, M, Y and K are determined so that a spatial frequency of dots formed in the reference area of each patch is close to the spatial frequency of the associated test area.

摘要： In a color deviation correction process, a printing apparatus prints a test pattern that allows highly accurate visual detection of a color deviation caused by output characteristic variations of individual print heads in the printing apparatus. More specifically, when patches of a test pattern are printed by mixing three colors, cyan, magenta, and yellow, the gradation value of each of the patch forming colors is changed in a gradation region close to a gradation value at which the saturation difference becomes maximum between a patch printed by the print heads having a central output characteristic with no deviation and a patch printed by deviating the gradation value of each color from the central output characteristic by a predetermined value.

摘要： An information processing apparatus, a printing apparatus, an information processing method and a printing method can print high quality images without lowering throughput by correcting density variations to within a range where they can hardly be perceived by the human eye as stripes or unevenness. With this invention, a print head having a plurality of nozzles capable of ejecting ink is used to print a test pattern based on image data with a predetermined gradation level. Then, based on read data of the test pattern, a temporary correction value &agr;′[N] is calculated which will made the print density of rasters corresponding to each of the plurality of nozzles constant. The temporary correction value &agr;40 [N] is limited by the upper limit &agr;U and the lower limit &agr;L so that it is limited to within a range between &agr;U and &agr;L.
