Abstract
Provided are an apparatus and method for correcting a mixing ratio of monochromatic dyes. The apparatus includes a memory, and a processor connected to the memory, wherein the processor estimates a first spectrum related to an absorption ratio or absorbance of a mixed dye from a reflection ratio by concentration for each of monochromatic dyes stored in the memory, estimates, from a reflection ratio of a desired color stored in the memory, a second spectrum related to an absorption ratio or absorbance of the desired color, and corrects a mixing ratio between the monochromatic dyes used in manufacturing the mixed dye on the basis of a result of comparing the first and second spectra.
