ColorThink vs GMG ColorServer

ColorThink is a color graphing and analytics tool for calibrating printing systems, checking accuracy, and preparing measurements for ICC profiling or color references. ColorThink 4 measures directly from connected instruments and sends results to a worksheet or graph. Color Assets organizes installed profiles and other color assets, with metadata filtering and sorting. Pro licensing adds gamut comparison by subtraction or addition and calculates a Gamut Comparison Index. Image animation is available across license levels, showing transitions between normal display and Lab color values in the grapher. PrePressPack adds nColor and color-list handling, device-link and ColorCast profile creation, white-point editing and remapping, and patch tuning. Listed instruments span X-Rite, Barbieri, Konica Minolta, Techkon, and Color Sentinel. The software runs on macOS and Windows; version 4.2 is listed for both. Photo licensing starts at $249, paid once.

GMG ColorServer converts print data from varied sources into a selected output color space for digital and analog printing. Its MX technology processes CMYK, RGB, ECG, and multicolor files while preserving the black channel and stabilizing sensitive color areas. Spot colors can be converted into the chosen output space, including fixed digital press sets such as CMYK or CMYKOGV, and extended-gamut workflows can use orange, green, and violet inks. A client-server architecture distributes processing across connected machines and supports simultaneous jobs. GMG lists workflow connections with ESKO, DALIM, Enfocus, and Kodak, plus API and XML job-ticket hot-folder integration. The software supports printer profiling and ICC profile management. Listed systems are Windows 11, Windows Server 2019, 2022, and 2025, and macOS 10.15 or later. OpenColor profiling requires version 3.0 for compatibility with the downloadable ColorServer version. Licenses are requested separately; upgrading from 5.x to 5.7 needs a new license. Pricing is on request.
