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.
