Abstract
An example method uses a spectrophotometer to collect reflectance curve data from a physical sample colored to a desired color. The reflectance curve data is employed to produce computer display outputs of substrates as they would be appear if colored with the desired color. The method includes using a colorimeter to collect calorimetric data from the outputs on the display. The sets of colorimetric data are compared and data that facilitate manipulating the reflectance curve data associated with the desired color is produced. The synthetic reflectance curve data facilitates producing matches for the various substrates as colored and displayed on the computer display. The synthetic reflectance curve data may also be used to manipulate colorant formulae.
