Summary:

The increasing use of prepress color proofing and the adoption of new types of inks makes rapid, objective color-matching and colorimetric calculations highly desirable. The inadequacies of densitometry and spectrophotometry will be briefly discussed and a system will be described which utilizes a CIE response, three filter colorimeter and a cube root color coordinate system (C.I.E. 1976 L*, a*, b* uniform color space system). The need for color matching over the entire tonal scale will be shown and a practical technique will be described for matching color toners to printing inks.
