A measurement position presentation guide indicating a measurement position of the print material is generated on the basis of the print image data. To achieve the second object, print image data is analyzed to extract a plurality of measurement candidate regions that are candidates of a measurement position. The number of measurement positions to be allocated to each of a plurality of measurement candidate region groups of which image signal values are different is determined. The measurement candidate region group of which the image signal value is within a predetermined range with respect to the measurement candidate region group to which the measurement position has been allocated is excluded from targets of allocation of the measurement position.
