Abstract
A multi-factor method of optimizing a quantity of inks in a spot color ink inventory associated with an ink inventory management system is provided. An electronic device performs the steps of: importing a first set of spot color data from the ink stock management system, setting a color tolerance, obtaining color differences between spectral information of pairs of color references in the first set of spot color data, identifying color references meeting a first replacement factor of having a color difference within tolerance of another color reference, designating a second color reference as a replacement for a first color reference if at least one second replacement factor is met, and exporting a second set of spot color data including the designated replacement reference colors. The step of obtaining color differences may comprise calculating a color difference value ΔE between pairs of color references.
