There is a common requirement among the various proprietary color management systems (CMS). It is the need to characterize the response of many different color output devices. Characterizations are typically the net result of thousands of measurements of a test target across several each of a given color output device. Color output devices can be classified as soft-proof (monitor), digital proof, or conventional output (film to off-press proof and to press sheet). In this paper we focus on characterization of reflective hard-copy output. Measurements of this reflective copy can be taken with any of several instruments: (1) Spectrophotometers (0/45 or sphere), (2) Spectral- based Colorimeters, (3) Tristimulus Colorimeters (with 3 or 4 filters). We compare the colorimetric identity of an array of color output devices as measured by spectral-based and tristimulus color measurement instrumentation. The output devices include a variety of pre-proofs, digital proofs, and conventional proofs, as well as ink-on-paper press sheets. Colorimetric assessment capabilities of less-expensive filter-based colorimeters versus those of more costly spectral-based instrumentation are evaluated. Comparisons will take the form of simple scatter plots in commonly-used CIE color spaces. The motivation for this research comes from the need to minimize the cost and effort expended by CMS users in creating localized custom characterizations for their mix of color output devices.
