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.

Abstract: An apparatus for predicting an absorbance spectrum of a mixed dye based on CCM reflectance data. The apparatus includes: an input module receiving input of a customer order for dyeing; and a processor reproducing an absorbance spectrum through conversion of reflectance data in a QTX file of the customer order, wherein the processor generates absorbance spectra and predicted colors through conversion of reflectance data of single-color dyes in a dyeing factory; implements a predicted absorbance spectrum of a mixed dye produced according to a recommended single-color dye mixing ratio corresponding to CCM values of the customer order; compares the predicted absorbance spectrum of the mixed dye with the absorbance spectrum according to the customer order; and complements or corrects the recommended single-color dye mixing ratio to match the predicted absorbance spectrum of the mixed dye to the absorbance spectrum according to the customer order.
