This version provides higher stability and fixes the following bugs:
-
Processing error for custom characterizations
For some custom characterizations no profiles could be created. The profile calculation in these projects ended with an error message. Please install at least OpenColor 3.3.0.8 and ColorProof 5.17.0.69 to fix this issue.

GMG OpenColor now supports the Epson SureColor SC-P20500, a high-performance solution designed for large-format proofing. With its 64” printing width and a resolution of 1200 dpi, this printer is ideal for stand proofing and imposition proofing with full press sheet simulation. In combination with the Calibration Creation Wizard in GMG ColorProof 5.17, you can create custom calibration sets and output conditions for OpenColor, ensuring reliable and consistent color reproduction across various substrates.
Epson SC-S9100 – Expanded color gamut for packaging proofs and prototypes
GMG OpenColor now supports the Epson SureColor SC-S9100, a high-performance printer optimized for packaging proofs and prototypes. With its 11-color UltraChrome GS3 ink system, including green ink, it delivers an extended color gamut for precise and vibrant results. The SC-S9100 is specifically engineered for printing with white on transparent and metallic films, ensuring consistent color reproduction even in the most demanding packaging applications. The Calibration Creation Wizard in GMG ColorProof 5.17 enables custom calibration sets and output conditions for GMG OpenColor.
Roland TrueVIS LG – Fast prototyping with extended color gamut
GMG OpenColor now supports the new Roland TrueVIS LG series, featuring dual print heads, an integrated cutting unit, and extended UV ink sets. The following ink configurations are supported:
- Eight colors: CMYK, Gloss, White, Orange, Red
- Seven colors: CMYK, Gloss, White, Red + Primer
This series offers a powerful solution for fast, precise, and super-realistic prototype proofing as well as small-run production. In combination with the Calibration Creation Wizard in GMG ColorProof 5.17, you can create custom calibration sets and output conditions for OpenColor, ensuring reliable and consistent color reproduction across various substrates.
Roland VersaOBJECT MO – Compact direct-to-object proofing with extended color gamut
GMG OpenColor supports the new Roland VersaOBJECT MO series, featuring compact UV printers ideal for object proofing and small batch production. These versatile printers support both 2D and 3D applications, enabling printing on a variety of substrates such as paper, wood, plastic, and other unique materials. In combination with the Calibration Creation Wizard in GMG ColorProof 5.17, you can create custom calibration sets and output conditions for OpenColor, ensuring reliable and consistent color reproduction across various substrates.
FOGRA55 support
GMG OpenColor now supports the FOGRA55 standard, featuring a global Expanded Color Gamut (ECG) characterization for Multicolor workflows. This enables more accurate color reproduction across Offset and Digital printing, helping to reduce color mismatches and rework while ensuring consistent, high-quality results for packaging, branding, and marketing.
Export spot colors as CxF
With the new chargeable "GMG OpenColor Export Option", you can now export custom spot colors as spectral-based Color Exchange Format (CxF) files to reliably share both solids and gradations across your entire process chain. You can choose to export single spot colors or entire spot color libraries. Learn more under Export spot colors as CxF file.
Export characterizations as CGATS
With the new chargeable "GMG OpenColor Export Option", you can also export your CMYK and ECG characterizations as L*a*b*-based CGATS files - for creating ICC profiles, output intent profiles, or for process control. The CGATS export option is available under Project > Separation >Tools & Actions > Characterizations > Export as CGATS.
Prevent spot color duplicates on CxF import
When adding spot colors from CxF files, you can now prevent duplicates from being added to the database by enabling the new "Skip duplicates" checkbox in the import dialog.
Improvements for separation profile calculations
Separation profile calculations were improved across RGB→CMYK, RGB→Multicolor, and MXN profiles, providing smoother transitions, better contrast, and more consistent gamut mapping. An option to calculate RGB profiles without Black was added, transitions between non-overprinting inks were refined, and spot color reproduction on dark media such as corrugated brown cardboards was enhanced.
End of service life (EOL): X-Rite i1 Pro 2
We hereby announce the end of service life for the X-Rite i1 Pro 2 series. Support for these devices via service hotline, email, or ticket system can therefore no longer be guaranteed. However, the drivers remain included in GMG products. See also: Supported measuring devices across GMG products
Resolved issues
This version provides higher stability and fixes the following bugs:
-
L*a*b* color corrections missing after application restart
When applying L*a*b* color corrections to secondary colors, the changes were not permanently saved and reverted to the original values after restarting GMG OpenColor. -
Duplicate spot colors in characterizations after CxF import
When adding spot colors from CxF files to a characterization, OpenColor did not warn about duplicate color names and added the colors again. This could lead to confusion and incorrect color usage in downstream processes. Now you can prevent spot color duplicates from being added by enabling the new "Skip duplicates" checkbox in the import dialog. -
MX4 import failed due to special characters in file name
MX4 files containing special characters such as “ß”, “ä”, “ö”, or “ü” in the file name could not be imported successfully. The calculation failed with an error message, although the file itself was valid.
Error message: "Error extracting Lab values" -
Wrong separation values with brown cardboard color spaces
When calculating separation rules targeting a brown cardboard color space, the resulting CMYK values were incorrect. Primaries did not remain 100% clean, and some spot colors were incorrectly mapped to the paper tint. Both issues led to poor visual results. -
High Delta E values with some in multicolor separations
In some cases, converting from CMYK to Multicolor resulted in suboptimal ink separation and usage. Some ECG inks were not utilized as expected, and additional channels were ignored. This led to increased DeltaE deviations and a less vibrant visual appearance than expected.
