What's new in OpenColor 3.1

New in version 3.1.5.9 - June 10, 2024

Calculate DotProof profiles even faster
Create more profiles in less time: GMG OpenColor 3.1.5.6 can now calculate MXD profiles for DotProof even faster than before. Please note that the actual speed also depends on your individual hardware configuration.

Achieve an even higher profile quality
With this update, you can achieve even higher quality for Multicolor-to-Multicolor separation profiles and for profiles from RGB to CMYK and ECG.

Export test charts as PDF file or CGATs measurement template
You can now export test charts as a single multipage PDF or as a CGATs measurement template file (.txt and .zip) by using the 'Export Test Chart' button under 'Tools & Actions' on the right window pane.

User interface improvements
We have revised the interface in several places to improve usability and enhance its visual appearance. Besides an improved characterization dialog, the adjustments also include a modernized gray color scheme, providing you with a consistent experience across all our products.

Resolved issues
This version provides higher stability and fixes several bugs. We recommend you to always install the latest GMG OpenColor version to benefit from all improvements.

The most important bugfixes:

• Processing error with white undercoat

  Profile calculation failed if the proofing condition contained a white undercoat.

  Error message: "Error processing"

• Processing error with smoothed measurement data

  Profile calculation failed if smoothing was applied to the measurement data.

  Error message: "Error processing"

• Failing color correction with smoothed measurement data

  Color corrections were not possible if smoothing was applied to the measurement data. Window status remained in ‘Pending refresh’.

• GMG ColorPlugin: Failing CMYK-to-Channel-Changer profile calculation

  Separation profiles could not be calculated if a process color was replaced by a spot color.

  Error message: "invalid vector subscript"

• Missing files after GMG OpenColor project export

  Channel extender profiles were not included in exported GMG OpenColor projects. After importing a project to another system, these profile variants were missing.

New in version 3.1.0.1837 - December 4, 2023

Resolved issues
This version provides higher stability and fixes several bugs. We recommend you to always install the latest GMG OpenColor version to benefit from all improvements.

The most important bugfixes:

• Layout changes in test charts after update

  Test charts from earlier versions had a changed layout after updating to GMG OpenColor 3.1 or after importing them into this version. This update resolves the issue and also corrects the remaining wrong test chart layouts.

New in version 3.1.0.1810 - November 28, 2023

Resolved issues

This version provides higher stability and fixes several bugs. We recommend you to always install the latest GMG OpenColor version to benefit from all improvements.

The most important bugfixes: 

• Layout changes in test charts after update

  The update to GMG OpenColor 3.1 altered the layout of test charts created in earlier versions. This led to measurement errors; the test charts could no longer be used.

New in version 3.1 - November 15, 2023

Import Lab based spot colors and convert them into spectral data

Manage and use all your colors in one common database — including spot colors from CxF files and DB3 libraries: with the 'Lab-to-Spectral' technology, you can convert Lab-based spot color data into spectral values and thus also use and combine them for other projects as you like. You can find a tutorial under the following link: Lab-to-Spectral: Import Spot Colors From CxF and DB3 Files

Save ink quickly and easily with new straightforward presets

It has never been easier to reduce the costs for digital printing: just select one of our new ink saving presets, and GMG OpenColor will adjust relevant parameters like the GCR level automatically before calculating an MXN separation profile. You do not want to use one of our ready-steady presets? Don't worry, of course you can still customize all settings individually if necessary. Learn more about ink saving and other separation settings under the following link: Ink Saving and Other Separation Settings

Calculate separation rules up to 5 times faster

Get more calculations done in less time: GMG OpenColor 3.1 can create separation rules for GMG SmartProfiler projects up to 5 times faster than before. Please note that the actual speed also depends on your individual hardware configuration.

Unlock flexible overprints with FM screening for inkjet printers

In the ink settings, the screening type 'FM Screen' is now available for inkjet processes. This allows you to define the overprinting behavior for each color of your inkjet printer individually and without limits. The correct screening type for your process is communicated by GMG SmartProfiler and automatically set in GMG OpenColor. More details will follow soon.

Create profiles with state of the art algorithms
We have enhanced our profile calculation algorithms to offer you an even higher profile quality and ensure consistency across different profiling methods.

Create profiles for HP DesignJet Z9⁺ PostScript® printers
GMG OpenColor supports the new printer models 'HP DesignJet Z9⁺ 24-in PostScript®' and 'HP DesignJet Z9⁺ 44-in PostScript®' (without dual roll). In combination with GMG ColorProof 5.15 and later, you can use predefined output conditions to create color accurate and reproducible proofs for a wide range of substrates. Please find further information under the following link: Supported Proof Printers, Proof Media, and Print Modes

Measure test charts with the new X-Rite eXact™ 2 series
GMG OpenColor supports all three models of X-Rite's new measuring device series: eXact 2, eXact 2 Xp, and eXact 2 Plus. The measuring devices offer a 30% larger screen than previous X-Rite generations to make measuring easier and more comfortable. Additionally, they provide a low-contact measurement area, helping you to avoid wet ink contamination which could lead to wrong measuring results. Please visit the X-Rite website to learn more about the new eXact™ 2 series.

Embrace the convenience of our dongle-free GMG Online Licensing
The Application Service coming with this version supports the new GMG Online Licensing. Online licenses are system-based licenses that you can use on a local machine or in a virtual environment. They are very stable and don't require a dongle that could break or get lost. Learn more about our online licensing and how you can easily switch for free: Online licenses

Resolved issues
This version provides higher stability and fixes several bugs. We recommend you to always install the latest GMG OpenColor version to benefit from all improvements.

The most important bugfixes:

• Slow connection to GMG ColorProof, Esko ArtPro+, and Hybrid PackZ

  A performance issue occurred in GMG ColorProof, Esko ArtPro+, and Hybrid PackZ when manually loading colors from GMG OpenColor 3.0 projects; the list was displayed too slowly. If you were affected by this issue, please enable this check box in the OpenColor settings:
  

• Error in connection to GMG ColorProof
  The dynamic GMG OpenColor standard downloaded into the GMG ColorProof database was, in some cases, corrupted. This resulted in GMG OpenColor inks that couldn't be displayed or jobs showing the error message: "Either OpenColor profile not found or no active connection to OpenColor."
• Inconsistent application of spot color target modes
  In some cases, the set target mode (absolute / relative) or the gradation was not applied correctly to spot colors.
• Crash during filter search in database view
  If, during the filter search in the database view, no results were found for the entered keyword, the application crashed instead of displaying an empty list.
• Low spot color saturation on dark paper tint
  In some cases, the separation rule calculation for spot colors on dark Kraft paper resulted in insufficient color saturation.
• Recalibration issues with GMG SmartProfiler projects
  Some projects could not be recalibrated.
