A printing apparatus corrects image data for printing on the basis of a color measurement result obtained by a sensor, prints a set of first color tone correction patches on a first sheet with a predetermined size and prints a set of a second color tone correction patches on a second sheet with the predetermined size. When the first sheet and the second sheet are printed one after another, a color measurement result of the tone correction patches printed on the first sheet and the second sheet is used in correcting the image data for printing. When the first sheet and the second sheet with the predetermined size are not printed one after another, a color measurement result of the tone correction patches printed on the first sheet and the second sheet for correcting the image data for printing is not used in correcting the image data for printing.
