New features

New Proofing Condition: GMG ProofMedia studio matte 150 OBA for OpenColor Dotproof

(chargeable license module OpenColor Dotproof required)

You can now calculate dotproof profiles for Epson SureColor P5000-7000-9000 violet and LLK, as well as for Epson Stylus Pro 4900-7900 on GMG ProofMedia studio matte 150 OBA.

An overview of the supported printers and proof media in OpenColor 2.1.4 is available on our website.


Gamut Mapping Option: Allow dimming of project to proofing media brightness

The option ‚Allow dimming Project to Proofing Media Brightness' is relevant if the white point of the production substrate is brighter than the proofing media, meaning if the paper white of the project media is not in the gamut of the proofer. The option ‚Allow dimming Project to Proofing Media Brightness' controls how the brightness difference between source and simulation color space will be handled during the profile calculation.

Option ON (default)

The project color space (source) will be scaled in a way that the white point of the project matches the paper white of the proofing media. The aim of adjusting the brightness before the profile calculation is to reduce clipping artefacts in the highlights of the proofs and to achieve a satisfying visual result. Due to the scaling, all colors of the project color space (in gamut, as well as out of gamut values) are adjusted/darkened, which might be a disadvantage when the proofs are verified colorimetrically.

Option OFF

The brightness of the project color space remains unchanged before the profile calculation. All in-gamut values of the project color space will be applied colorimetrically. The part of the project color space, which is out of the proofer gamut will be reduced to the proofer gamut during the profile calculation. The aim of deactivating the brightness adjustment is a colorimetric application of the project color space. Possible visual effects, such as loss of detail in the highlights of the proofs, are accepted.

Embedded Gamut in MX4x Separation Profiles

(chargeable license module OpenColor separation & chargeable ProfileEditor required)

The separation profiles for ‘CMYK-to-CMYK’ or ‘RGB-to-CMYK’ have now an embedded gamut file, which can be extracted in the latest ProfileEditor and loaded in the Gamutviewer or as gamut in the SpotColor Editor.

Spot color databases – Filter by Target Mode

Spot color lists can be filtered by target mode (Media Relative, Absolute or Custom).
 

Winner of the EDP Award

GMG OpenColor has won the EDP Award for the best color management.

“This product gives printers the freedom to mix their own color sets and make color separations for that using the maximum color space. It also works for digital print and LFP. And allows accurate colors in proof and print.” - Technical Committee's opinion
 

Resolved issues

The following technical issues have been resolved in GMG OpenColor 2.1.4.132.

Channel name blank
The channel name showed up as blank in the project after changing the channel name in the characterization. [35929]

Custom Spotcolor not available as project color
Inks that were selected as project colors from custom spot color databases did not appear in the list of selected inks. They were not available for profile creation. [40322]

Changing selected colors in a characterization did not affect linked projects
Changes in the characterization, such as activating/deactivating spot colors were not applied to the associated projects. [18108]

Wrong Ink Usage caused bad separation profiles
In one use case the inks of the spectral data were mapped wrongly (yellow to cyan and vice-versa). This was the cause of very bad separation profiles. [18833]

Min. value for new test charts
If the height of a new test chart was set to the minimum value by entering manually 15,5, or by decreasing height using the down arrow adjacent, this value was not applied. [78702]

DotProof iteration – Dark proof simulation
If the production media was brighter than the proofing media (meaning the white point of the production substrate was not in the gamut of the proofer, which is an unusual case) the dotproof profiles tended to be too dark.

This happened in projects of the OpenColor versions 2.1.1 – 2.1.3. The bug fix in OpenColor 2.1.4 is limited to the calculation of new dotproof profiles. Available dotproof profiles calculated in previous versions are not changed. Dotproof profiles from affected projects (production media brighter than proofing media) need to be recalculated to correct the darkened target values of the profile.

Profile check sum change
Profile changes resulted in a new check sum. When the changes were undone, the check sum was not reset to the original check sum. With the bug fix in OpenColor 2.1.4, the check sum is reverted to the original check sum, when changes are undone.

As a side effect of this bug fix will profiles, which are re-calculated in OpenColor 2.1.4 with the same settings in OpenColor 2.1.3, have a different check sum.

 

End of Life

Please note that we will no longer provide bug fixes, maintenance releases, workarounds, or patches for bugs found in GMG OpenColor 2.1.3.193 or older.
