System Requirements
Installation and update instructions
  1. Extract the zip file
  2. Double-click Setup_5.0.50040.exe to start the setup
  3. Select the modules to be installed on that system
  4. (Repeat on other systems for distributed processing)

First start after installation
After installing ColorServer 5.0, the first start takes some minutes. As long as the server data are updated, the http-server is not running, the client is disconnected and shows the ‘red’ status. A pop-up message reminds to wait until the configuration is finished. The duration of the first start depends on the size of the server data and the computer performance. Once all data is updated, the Client connection will turn to the ‘green’ status. This is valid for new installations as well as for updates.

New features

PSR LWC plus v2 M1 Profile

The print standard PSR LWC plus V2 M1 is an update of the Process Standard Rotogravure on LWC plus paper (based on gamut type 2 from ISO 12647-4). The update consists new M1 target values. (The previous print standard PSR LWC plus V2 was based on measurement condition M0.)

According to the European Color Initiative (ECI), improvements and goals of this update are:
  • Compatibility with other standards
  • Use of new color values measured under M1 conditions
  • Use of new viewing conditions
  • No change on press side
  • Alignment with ISO 12647-4:2014

Conversion profiles
Separation profiles

SmartProfiler: Printing without black ('CMY-only')

Digital printing knows some use cases for printing without black. Printing ‘CMY-only’ saves clicks and impressions, as the black channel is not used. Production is increased, because more jobs can be printed in the same time.

SmartProfiler includes a new preset for the creation of conversion profiles without black channel.

Default settings for manual jobs

Manual jobs are often created with the same settings. To save time, the selected templates will be used as default setting for the next manual job.

SmartProfiler: Profile iteration

SmartProfiler profiles for digital printing devices can now be checked and improved by iteration. The process can be started by right-clicking on the SmartProfiler resource.

Embedded gamut files in spot color databases

This option makes it easier to add spot colors to spot color databases, that have been generated by SmartProfiler. The export of the spot color database from ColorServer will automatically include the gamut of your digital printer. This gamut file can be selected in SpotColor Editor.

The gamut file can be exported from a Smart-Profiler generated MX profile as well (right-click).

Direct access to linked resources

The overview of the linked resources has been optimized by hyperlinks in the info pane, which allow to directly access and edit the templates.

Resolved issues

The following technical issues have been resolved in GMG ColorServer 5.0.50040. Please note that the list describes the problem, not the solution.
Language of ProfileEditor always German
GMG ProfileEditor was started in German, irrespective of the system language or the language set for the ColorServer application [73054, 76539, 76705, 76682, 76822, 77504, 77785, 77694, 77774, 00829]

Incorrect interpretation of Korean characters
Use of Korean (hangul) characters in any of the used paths or file names caused the SmartProfiler to abort with an error during the creation and publishing of SmartProfiler resources [00242]

InkSaving report not generated without REST-API license
Exporting an ink saving report aborted with an http-error 401 (no rest-api-license) [01587, 01976, 01967, 01830]

High-load loss of connection
Under heavy load, the connection between Workers, Clients and Server sometimes got unstable, resulting in a temporary loss of connection and jobs aborting with errors. [01882]

Unable to load ink saving report xml containing & character
Report files containing the ampersand character (e.g. as part of the processed file’s name) could not be loaded into the report tool. It instead aborted with an XML error. [02267]

Error during image processing - Unable to create Output file
One customer file aborted with the above error due to problems processing the embedded XMP data [02298]

Very large files (e.g. 5.2 GB) aborted with error
Attempting to process a 5.2 GB PDF file aborted with a read/write error. [02341]

Image hotfolders: No normalization with sharpening
In an image hotfolder, activating the sharpening prevented any sort of color conversion during the normalization step. [UK-8057]

Change of install path impossible
During installation, changing the paths away from the default settings was not possible due to a missing button. [02503]

Incorrect flattening of overprinting objects
When printing with flattening and “preserve overprint” active, certain DeviceN objects could not be flattened correctly. [02503]

Use of db3 with proofing features caused error during processing.
In a workflow set to convert spot colors using a spot color database containing proofing features (Silver/white/gloss inks), the conversion aborted with an error "gmg::MXEngine::Exception: ColorantsMismatch”. [UK-8268]

Error on export and backup if user has special characters
Creating exports of resources or complete backups of the Colorserver configuration aborted with an error if the user name contained special characters such as accents. [02854]

Name reverted to original on export
Exporting a hotfolder after changing its name showed the old name in the export as well as the imported hotfolder. [02696, 03212]
