GMG ColorServer vs OpenColorIO

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.

OpenColorIO is a free color management solution for motion picture production, particularly visual effects and computer animation. It supports artists managing color, studios integrating color management into pipelines, and developers building or upgrading color management frameworks. Its Python API can connect a studio pipeline or modify a configuration. Config merging is in preview, with controls for name and alias conflicts and duplicate color spaces. The GPU renderer supports the Khronos Vulkan graphics API, and the project describes ACES 2.0 support as feature complete, including ACES 2.0 Output Transforms as OCIO views. OpenColorIO also supports Color Interop ID and attributes for ICC and AMF. Listed integrations include Blender, Autodesk Maya, Houdini, Nuke, Photoshop, and Unreal Engine, with some version requirements, including Blender 2.64 and up, Maya 2016 and up, and Unreal Engine 4.22 and up. It is available as an API and for Linux, macOS, and Windows under the BSD-3-Clause license. Prebuilt libraries are available through package managers; Python bindings and command-line tools can be installed from PyPI.
