Missing email notifications after update

After upgrading to version 5.16.0.52, users did not receive feedback indicating that the configuration for outgoing email notifications had to be updated. The 'User OAuth2' setting needed to be defined as 'None' or 'Microsoft'.

Wrong email recipient for remote proofing notifications

Email notifications were sent to the sender's email address instead of the intended recipient or remote site address.

Unrecognized spot colors in remote proofing jobs

The spot colors in remote XML jobs were no longer recognized if the job was moved to another printer queue.

Deactivation of automated job import setting in remote proofing

After upgrading to version 5.16.0.52, the activated remote proofing setting 'Automated Job Import via Hotfolder' was incorrectly no longer active.

Object reference error for measure jobs

Some print jobs from the jobs queue failed at the label printing stage.

"Object reference not set to instance of object"

Unprocessed files in hotfolders with wait time enabled

Hotfolders with the 'Wait before processing: 1 min' setting enabled did not process files that had an old creation date.

False OpenColor project change warning

Depending on the proof mode (CT/DP) and the image data (spots/no spots), OpenColor jobs sometimes incorrectly triggered a warning about a changed linked OpenColor project. This issue occurred only on Spanish, Italian, and German operating systems; English systems were not affected. In order to fix this issue, please install GMG ColorProof 5.16.0.96 as well as GMG OpenColor 3.2.0.37.

"Il progetto OpenColor collegato è stato cambiato. È possible continuare a stampare o ricalcolare un nuovo profilo." / "Output prova: il Progetto OpenColor selezionato è cambiato." / "Das verlinkte OpenColor Projekt wurde geändert. Sie können den Job trotzdem drucken oder ein neues Profil berechnen." / "Proof-Ausgabe: Das ausgewählte OpenColor Projekt wurde geändert."

Unclear verification results for GMG Spot Color V2.0 strip

The verification results of the GMG Spot Color Strip V2.0 were not presented to users in a transparent way, as the overview only displayed the maximum delta-E value per ink (50% or 100%). The UI now clearly indicates whether the delta-E value corresponds to the 50% or 100% patch.

Missing Out-of-Gamut flag on GMG Spot Color V2.0 label

The Out-of-Gamut flag was missing on the label of MXN-based jobs if one of the spot colors in the Spot Color V2.0 strip exceeded the tolerances.

Several performance issues

Several performance issues have been resolved, including unexpected end of printing with parallel MXN jobs, a memory leak causing intermittent license errors, and excessive RAM consumption.

Paper tint not removed in dynamic OpenColor jobs

The paper tint in dynamic OpenColor jobs was not removed after disabling the ‘Use Paper Tint Simulation’ option.

Print issues with OpenColor jobs containing CxF spot colors

OpenColor jobs with technical spot colors defined by a CxF definition could not be printed.

Application start via task bar icon not possible

GMG ColorProof could not be started by right-clicking the taskbar icon and selecting ‘Start GMG ColorProof’.

Enhanced information dialog in Manual Job Manager
The information dialog in the Manual Job Manager, accessible via Toolbar > 'Info' icon Info, has been expanded and now includes detailed profile information. For example, it displays the checksum, measurement condition, GMG OpenColor project, and various ink parameters such as data source, L*a*b values, and whether colors are in gamut or out of gamut. In the event of a problem, this information can help you identify and resolve the cause of the error more quickly.

Connection issues between GMG ColorProof and GMG OpenColor

After updating to GMG ColorProof 5.16 and GMG OpenColor 3.2, various connection issues arose between the two applications, leading to one or more of the following problems:

  • GMG OpenColor jobs could not be printed, and the following warning message was displayed persistently: "Proof Output: Selected OpenColor Project has changed."
  • Color channels from jobs were not mapped.
  • GMG OpenColor proof standards were incorrectly displayed as ‘disconnected’ despite GMG OpenColor being active and connected.
  • When downloading GMG OpenColor projects, the keyword filter defined in GMG ColorProof's general system settings was ignored.

Synchronization issue with static profiles

Static profiles could not be loaded into the GMG ColorProof database.
Please ensure you install both the latest GMG ColorProof patch and the upcoming GMG OpenColor patch to fix this issue!

Request profiles for GMG DotProof dynamically
In combination with GMG OpenColor 3.2 and later, you can now also request MXD profiles for GMG DotProof dynamically. To do so, a project with an iterated CMYK profile must be created and published on the GMG OpenColor side first. You can then sync this project with GMG ColorProof (Database > Download > From GMG OpenColor) and use it for your DotProof jobs. Please note that you cannot use the same project for DotProof and Contone, but that you will need a separate project for each profile type instead.
Use spot color definitions from CxF for dynamic MXN profiling
GMG ColorProof now automatically detects and reads out embedded CxF spot color definitions from your PDF Files. In combination with the GMG OpenColor project inks, the spot color definitions from the document can then be used for the dynamic multicolor profile calculation. Please follow the link for detailed instructions: Spot color descriptions in the form of CxF/X-4 spectral data
Find channel mapping rules faster via the search filter
Managing numerous channel mapping rules can be confusing and time-consuming. With the new search filter in the rule set overview and in the mapping dialog, you can assign channels more efficiently: Just enter a keyword into the search bar to filter the list for entries containing that keyword, allowing you to find the required rule quickly and easily. Are you curious to see what the new search filter looks like? Then follow the link: Search filter for mapping parameters
Change the GMG OpenColor IP address for all standards at once
The IP address of your GMG OpenColor instance has changed? Good news: Instead of tediously changing the address for all GMG OpenColor proof standards individually, you can now use the new batch change functionality from the general settings to update the address for all standards at once with just a few clicks. Please follow the link for detailed instructions: How to change the IP address for existing OpenColor proof standards...
Restore remote sites on different machines
When creating an environment backup as an Admin, you can now decide if the remote site settings should only be restorable on the machine on which the backup is created, or if the data from the backup is allowed to be restored on different machines as well. Learn how it works under the following link: How to create a backup...
Proof with the new 'GMG ProofMedia studio matte 200'
GMG ColorProof 5.16 supports our new 'GMG ProofMedia studio matte 200', designed for print simulation on OBA-free production substrates in the packaging sector, such as folding boxes and corrugated cardboard, as well as decoration or letterpress printing. Its high grammage provides excellent mechanical stability and a consistent print image, even with heavy ink application. With high brightness, it offers a larger color space in highlight areas than many other matte proof media, allowing to reproduce even the finest structures with high color intensity and consistency on its smooth surface. 'GMG ProofMedia studio matte 200' is available in 13", 17", 24", and 44" widths. Under the following link, you can learn more about our media portfolio and download additional information material such as product sheets, certifications, and our FSC® policy: GMG ProofMedia
