1. A print control apparatus comprising: an area sensor that images a plurality of second pixels of a test pattern in an imaging range of the area sensor and generates image information of the test pattern as a plurality of first pixels with the first pixels being finer than the second pixels, the test pattern being printed on a printing medium; a reference color-measuring sensor that color-measures intensity of a reflected light in multiple wavelengths from the test pattern in a color-measuring range of the reference color-measuring sensor and obtains a reference color measurement value of the test pattern based on the intensity, the reference color-measuring sensor being more accurate than the area sensor in measuring concentration of a color of the test pattern, the color-measuring range overlapping with the imaging range; and a controller that generates a correction value based on the image information and the reference color measurement value, and corrects a color of printing data of a printing image based on the correction value to form the printing image on the printing medium according to the printing data corrected based on the correction value.
