Color matching of liquid colorant

Abstract

Abstract PURPOSE:To provide a computerized and automated process for matching the color of a liquid colorant which is made laborsaving by dispensing with sampling. CONSTITUTION:A process for matching the color of a liquid colorant comprising performing computerized color matching by determining the amount of a colorant as a primary color to be added from the difference between the spectral curve of the standard liquid colorant and the corrected spectral curve obtained by correcting the spectral curve of the liquid colorant in the mixing tank determined with a remote spectrophotometer for the distance between the surface of the liquid colorant and the light-receiving surface of the remote spectrophotometer.
