1. A control method for an information processing apparatus, the control method comprising:
identifying a special color region in an image to be printed, the special color region being a region including a pixel having a pixel value corresponding to that of a region to be printed using at least a special color ink, wherein a color of the special color ink is other than a process color;
detecting an approximate color region from surrounding pixels of the special color region identified in the identifying, the approximate color region being a region including a pixel with a pixel value which is different from the pixel value of the pixel of the special color region by a predetermined threshold or below and which corresponds to that of a region not to be printed using the special color ink; and
displaying a predetermined presentation based on that the approximate color region has been detected in the detecting and not displaying the predetermined presentation in a case where the approximate color region is not detected in the detecting.
