DisplayCAL vs GMG ColorServer

DisplayCAL is a free display calibration and profiling solution built on ArgyllCMS, available for Linux, macOS, and Windows. With a supported measurement instrument, it measures displays and creates calibrations and ICC profiles, including for multi-display setups. Users can verify profiles and display devices, measure screen uniformity, and create video 3D LUTs with optional CIECAM02 gamut mapping. Colorimeter corrections can be imported from vendor software or created from measurements when a spectrometer is available. A test chart editor makes patch charts and accepts pasted data from CGATS, tab-delimited CSV, and spreadsheet applications. Documented pattern generators include madVR and DaVinci Resolve 10.1 or later; Chromecast support is optional. DisplayCAL requires ArgyllCMS 1.0 or newer and a supported measurement instrument. The software is licensed under GNU GPL version 3 or later and comes without warranty. The download page provides SHA-256 checksums, while the site links to forums, a wiki, documentation, help, and an issue tracker.

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.
