ABSTRACT:
A color match predictability system having a color sample, a predictability guide with sections having varying degrees of halftones, a spectrophotometer, and a computer with input and output devices. A light is directed at the color sample and then passed into the spectrophotometer where its color spectrum is analyzed, converted into data, and fed to the computer. A colorant formulation is calculated by the computer for the original color sample and for a series of modified samples including different halftone sections superimposed on the original color sample. The quality of the color match for the various formulations is analyzed to determine the formulation having the best possible color match. The modified sample having the best color match may be viewed by the user to predict the color of the final product.
