DeviceLink/Printer Profiling
Improved Multicolor Generation
The improved Color Generation optimizes color reproduction in the Multicolor modes Strong, Smooth, and Generate Separations with sparse inks:
- Larger gamut in several cases: The optimized Multicolor Generation achieves a larger gamut in several cases when using Multicolor Modes Strong, Smooth, and Generate Separations with sparse inks.
- Improved: Generate Separations with sparse Inks
The Multicolor mode “Generate Separations with sparse inks” improves for multicolor printer profiles and DeviceLink profiles the use of gamut-extending colors and reduces the number of channels used, depending on the data and color set. At the same time, the use of gamut-extending colors (such as Orange, Green, Violett, etc.) is largely avoided in the gray balance and near-neutral tones. - Improved profile precision and quality
The size of the Look Up Tables (LUTs) for 6-, 7-, and 8-color profiles has been increased and harmonized, enabling better profile accuracy, quality and gamut volume across different profile color spaces.
This results in larger profile sizes and longer calculation times for the “Medium,” “Large,” and “Very Large” profile sizes, especially for 8CLR profiles.
Optimized Black Generation option MaxK now uses more black
The MaxK black generation mode (which forms the basis for the Generate separations with sparse inks multicolor mode) has been improved by generating separations using the maximum amount of black and minimum amount of CMY.
This not only results in a lower total ink volume for the Gray Balance due to the improved distribution of black versus CMY, but can also lead to a larger color gamut and more pure colors.
It is also possible to set the Black Start in conjunction with MaxK.
But keep in mind that this leads to strange but understandable curves as can be seen in the screenshot below. If the black start is not zero only CMY can be used to build the gray balance hence there is lots of CMY up to the black start. Only after the back start value the CMY will go down to a MaxK separation again leading to the buckles you see in the screenshot. This works reasonable for low Black Start values up to 15-20%.
Note: Using a late Black Start is not recommended in combination with Generate separations with sparse inks. If a late black start (e.g. 20% and higher) is required it is recommended to switch to a different Black Generation mode (e.g. GCR), as this conflicts with a MaxK setting.
That is why a warning is displayed in CoPrA.
Use all Multicolor channels where possible
CoPrA typically uses the channels in multicolor profiles that produce the widest possible color gamut. In this process, secondary colors—such as “magenta + yellow”—are replaced with “orange.” However, if the additional channel is not a color-space-expanding orange or red and the channel cannot be used for channel combination, then CoPrA does not use this channel in the profile.
The option Use all Multicolor channels, if possible allows the use of all Multicolor channels (according to the profile settings), even if the above-mentioned conditions may not be met.
This may result in profiles with a smaller color gamut or breaks in gradients. Therefore, profiles should first be generated without this option and, if necessary, evaluated in the Profile Report.
New Highlights Clipping option
Highlights Clipping refers to a controlled adjustment of the tone value distribution in the highlights (i.e., the brightest areas of the image) to meet the specific requirements of the flexographic printing process. In flexographic printing, very fine screen dots - especially below the first printable percentage value (e.g., < 3%) - often cannot be reproduced stably or at all. These tone values are therefore deliberately clipped, i.e., removed from the print image or smoothed.
The aim of this measure is to avoid printing problems such as missing halftone dots, uneven gradations, or disruptive artifacts. By controlling the cut-off, you can ensure that only the tone values that can actually be printed are reproduced—without any unpredictable losses or compromises in quality.
Typical applications are found in prepress, for example in tone curve adjustment or in the rendering of images for flexographic printing. Here, for example, the area between 0% and the first printing percentage value is replaced by a gentle tone adjustment (tone compression).
Example: To ensure clean gradations in the highlights, a controlled tone value cut-off was implemented at 2%. As a result, printing only begins at the stable printable screen dot at 3%, without any unwanted loss of detail.
The calculated profile can be used for both proofing and separation (Production).
Printer Profiling
Measurement of ambient (emission) light directly from CoPrA
So far, CoPrA's Emission option has used spectral emission light measurements, where CoPrA extracts the white point from the file and uses this info to create a printer profile.
In CoPrA 12, the Emission option has been expanded to provide the ability to conduct direct measurements from within CoPrA using the Measurement Tool in Ambient Light Measurement mode. This mode allows the spectral emission of a light source to be measured as a single color patch.
In CoPrA 12, there are now two Emission options:
Emission (Open File…): Use an existing measurement file with spectral emission values (as a CxF or text file) for a specific light source. The data can be loaded or imported using drag & drop.
Emission (Measure…): Opens the Measure Tool in Ambient Light Measurement mode. The ambient light can be measured directly from within the tool using supported devices (e.g., X-Rite i1Pro, Konica-Minolta FD-7 or Myiro 1). For more information, see the Measure Tool help.
Enhanced Gray Balance adjustments for a* values
The Gray Balance option has been expanded and now allows adjustments toward green (negative a* values) or red (positive a* values).
This can be done separately or in combination with the existing method towards cooler (negative b* values) or warmer gray (positive b* values).
The results of these adjustments can also be found in the Profile Report in section 2. Color Generation as a* b* values.
DeviceLink Profiling
New Rendering Mode Paper White/OBA Match to improve visual consistency for colored and brightened papers
The feature Paper White/OBA Match optimizes print results when there are significant differences between the paper white of the source and target media. It ensures significantly improved visual consistency, especially with strongly brightened papers. More precise adjustment to papers with high proportions of optical brighteners results in more harmonious and natural color reproduction—even with demanding print jobs.
New Highlights option Auto – based on Profiles
The new Highlights option Auto - based on Profiles simplifies the use of Highlights in the DeviceLink profile. This option applies the settings from the source or target profile in the DeviceLink. This ensures that the correct settings and values are used.
Note: When selecting a Highlights option, a recommendation is displayed when a Highlights option has already been applied to one of the selected profiles. This is to prevent corrections to the highlights from being applied twice.
Update Profile/DeviceLink
New Correction DeviceLink presets
Two new presets are now available for creating Correction DeviceLink profiles (e.g., for ZePrA). The presets are available in both the Update Profile and the DeviceLink tool.
The new presets Correction DeviceLink - Analog Printing and Correction DeviceLink - Digital Printing feature optimized Exceptions and separation settings for their respective application areas, which improve their quality and thus lead to better print results. The preset used is also listed in the corresponding report.
SaveInk
Information on ink savings in the GUI before profile creation
When adjusting the SaveInk settings, the amount of ink saved is now displayed directly in the GUI beneath the graphic on the right. When settings are changed or reapplied, the amount of ink saved is immediately recalculated, ensuring that the updated savings information is instantly available and can be considered before creating the profile.
This real-time feedback greatly enhances the ability to fine-tune SaveInk settings, making it easier to identify the most effective configuration.
The savings displayed refer to a Small profile and may differ slightly for other profile sizes.
Batch Overview
Creating log files containing the information of the Batch Overview
The Batch Overview provides a list of all tasks that are currently being processed. The list is automatically updated when tasks are started, e.g., new profiles that are being created are automatically displayed when profile creation begins. All tasks in this list are processed sequentially.
Now, the content of the task list can automatically be stored as a csv-log file when closing CoPrA.
The path for the log files can be specified in the Preferences window, and automatic creation of log files can be enabled or disabled.
Linearization
Linearization curves can now be saved in Text and CGATS formats
In addition to the curve formats ACV (Adobe Photoshop) and XML (ISO18620:2016), linearization curves can now also be saved as CGATS-compatible ASCII Text or in JSON-based cfcurve format for the HYBRID CLOUDFLOW application.
In addition, the curves can also be saved within the Batch Overview or the Profile Manager, if required.
General
Modernized and streamlined licensing management
From now on, ColorLogic products will be using the secure and well-proven Hybrid Software Group licensing system, which is also used in Hybrid Software GmbH products such as PACKZ and iC3D and is utilized by thousands of users worldwide. In addition to modern and secure encryption technology, this change offers other advantages as well:
- Only a single license key is required. The license key is linked to a user ID, not to a computer or hardware, and can be used on any system (Windows and macOS).
- Easier computer switching. When switching to a computer you no longer need to request new licenses, as the previous hardware- or dongle-based serial numbers are no longer used. Simply deactivate the license on the current computer, transfer it to another computer, and reactivate it there.
- This new licensing system is Internet-based. An Internet connection is required to activate or deactivate a license, but after activation the software can be used offline. This significantly reduces administrative efforts and increases flexibility when switching computers.
- Simplified update process. Previously, a new license was required for each new major release, but now you automatically receive all updates as long as your Software Maintenance Contract remains active.
- Includes the new Activation Manager application which allows you to manage all your license keys.
To use the new licensing technology, you must initially log in to the Hybrid Software Group Data Center. There, you will find all the software products you have licensed (under My Licenses), as well as the latest versions available for download (under My Products).
Improvements and Bug Fixes
General
- Enhanced Test charts: The predefined test charts have been reorganized, updated, supplemented and are now available for both the X-Rite i1Pro series and the Barbieri Spectro LFP. Additionally, new test charts for linearization have been included. Most test charts are available for the CMY, Gray, RGB, and CMYK color spaces. For Multicolor color spaces, test charts can be created using ColorAnt.
Preferences
- For CoPrA SP licenses, the Custom Profile Folder is no longer supported in order to avoid conflicts that can arise when Multicolor Profile Variants and the main profile are written to different folders (Ticket #264857)
Printer Profiling
- Profile Report: Fixed an issue where the profile report did not take colorant information into account and displayed incorrect TVI curves and K-channels for profiles with custom channel order.
- When spectral data are used, the target Illumination and the Observer are written into the profile's “targ” tag table as WEIGHTING_FUNCTION when they deviate from D50/2°
This is helpful because ColorAnt 12 checks the settings under Viewing Conditions in the Evaluate tool and displays either a Warning! or a Question to correct any differences between the measurement data and the Comparison Data Set or Profile.
This information about discrepancies is also displayed in the Evaluation report and on the Label.
- The detection of the TAC from profiles has been improved. As a result, the TAC in the profile report may differ compared to previous versions.
DeviceLink Profiling
- Fixed a problem when using a Multicolor target profile with custom channel order in conjunction with gray balance.
In gray balance, gamut-extending colors were used in addition to CMYK, resulting in deviating gray balance curves, black point and smaller gamut volume. This problem did not occur if the setting Automatic Channel Settings with TAC from target profile was used.
- Improved Border Clipping: The Border Clipping option in the Exception tab has been improved, so that the percentage values between 0.5% and zero will be set to 0% and values between 98% and 100% will be rounded up to 100%. This results in pure tones which no longer need to be screened in printing.
DeviceLink/Printer Profiling
- Additional Colorant Information in the Profile Report
In addition to the color information in Lab (relative colorimetric), the Lab values have been added in absolute colorimetric, so that the absolute color values are immediately visible.
This allows for better comparability with other applications, such as ColorAnt, where the absolute color values are displayed.
This applies to both the Printer Profile Report and the DeviceLink Profile Report.
Update Profiling
- Extended Reports: The Profile Comparison Report and the DeviceLink Correction Comparison Report now also provide information on G7 Correction, if this option is used in the updated profile.
- A problem has been fixed where the Save/Next button was disabled by the Batch Overview. When navigating back from the Batch Overview window dialog, it was not possible to calculate additional profiles without changing the settings.
Linearization
- Improved Profile Report with additional input values
The table showing the corrected input values for each process color has been supplemented with additional information. Instead of 12 input values as in CoPrA 11, 21 input values are now displayed. This provides more detailed information about the linearization curves.
- Improved Automatic Ink Limitation
The automatic calculation of the ink limit in the linearization has been improved so that it slightly higher values are now calculated automatically.
It is still possible to enter the limit value for each channel manually.
SaveInk
- To improve the comparability of CMYK and Multicolor ink savings, the Black Start values for the Multicolor TAC limit settings 220 and 300 were increased from 55% to 60%. As a result, the Ink Saving Options for the CMYK and Multicolor TAC limit settings 220 and 300 are now identical and comparable.
Batch Overview
- Fixed an issue where incorrect color space information was displayed for Correction DeviceLink job tasks. Instead of the job type ProfileCorrectionDL I NoSpace, the correct color space is now displayed (e.g., ProfileCorrectionDL I CMYK – CMYK).
Recalculation
- Active threads are now limited to 75% of CPU capacity to prevent overloading the system during profile calculations.
CoPrA 11.1.4 Release | February 2026

- Profile Manager / Batch Overview: Fixed an issue where the calculation of Multicolor profile variants from updated Multicolor profiles failed (Ticket #254584)
- DeviceLink Profiling: Fixed an issue where changing Settings, Black Calculation or the Multicolor Mode would cause incorrect Channel Combination curves to be displayed in the CoPrA Curves view and included in the resulting DeviceLink profile
- DeviceLink Profiling: Fixed an issue where the Black Calculation mode Auto based on Target Profile overrode the Multicolor Mode "Use Settings from Target Profile"
- DeviceLink Profiling: Fixed an issue where the embedded Multicolor Mode from the target profile was not extracted and used correctly with the Multicolor Mode “Use Settings of the Target Profile” (Ticket #254734)
- DeviceLink Profiling: Fixed an issue where the embedded Multicolor Mode “Generate Separations with sparse Inks” from the target profile was not extracted and used correctly with the Multicolor Mode “Use Settings of the Target Profile”
Improvements
- DeviceLink Profiling: The Multicolor Mode is now also included in the DeviceLink profile reports
The report now includes the used Multicolor Mode. In addition to the user-defined modes (Strong, Smooth, Generate Separations with sparse Inks, Use CMYK only, Preserve Color Properties) when using the mode Use Settings of the Target Profile the report includes the used mode from the target profile in parentheses
CoPrA 11.1.3 Release | June 2025

- Printer Profiling: Fixed an issue where the Measurement Correction returned incorrect values for the 400% patch and other overprints due to incorrect interpretation of data for a specific CMYK chart
- DeviceLink Profiling: Fixed an issue where the import of settings from DeviceLink profiles failed when the Save Ink option was selected for the Black Generation (Ticket #254444)
- DeviceLink Linearization: Fixed an issue where profile settings that were based on the Calculation method Ink Splitting could not be imported
- DeviceLink Linearization: Fixed an issue where the Protect Lights settings were not imported from profile settings
- Measure Tool: Fixed a bug in the Windows version of CoPrA where the latest version of ColorAnt 11/MeasureTool 8 was not recognized correctly (Ticket #254517)
CoPrA 11.1 Release | January 2025
Improvements in CoPrA 11.1
DeviceLink Profiling
- Improved drag and drop of profiles and settings. Now all profiles and settings can be imported at once when holding down the command key (macOS) or CTRL key (Windows) during drag and drop
Profiles can be manually set as Source and Target Profile in the DeviceLink-Profiler, either by selecting the profiles in the drop-down menus or by entering a few letters in the search field and selecting one of the profiles found. However, you can also drag and drop an existing DeviceLink profile over the profile menu. Settings from certain DeviceLink profiles can also be imported by drag and drop.
All this can now be done in a single step.
Select the DeviceLink profile from your Profiles folder and drag and drop it onto the Setting menu while holding the CMD key (macOS) or CTRL key (Windows).
The source profile, the target profile and the settings used are automatically loaded when the profiles are available in the Profiles folder.
This simplifies the initial setup and allows for quick and convenient selection of profiles and settings.
- New Presets for Correction DeviceLinks (CMYK and Multicolor): Correction DeviceLink – Analog Printing and Correction DeviceLink – Digital Printing
The two new presets are intended for analog and digital printing, respectively. Their settings are optimized to provide a good starting point for typical Correction DeviceLink use cases and can readily be adapted for special applications if required. The previous preset Default - Correction DeviceLink has been removed.
DeviceLink / Printer Profiling
- New status display for calculations of Curves, Exceptions and Gamut in the notification area at the bottom of the window
Image Conversion
- Image based ink savings achieved by using SaveInk Multicolor profiles or Multicolor source and target profiles with same numbers of channels are now displayed
In addition to the CMYK-to-CMYK conversions or the CMYK SaveInk DeviceLink profiles, the image based ink savings are now also displayed for Multicolor SaveInk profiles or Multicolor source and target profiles with the same number of channels.
Note: Please note that this is an information about image based ink savings which applies to the conversion of the selected image file. Therefore, different results may be obtained for different image files.
Printer Profiling
- Consistent display of DCS and Lab values for the black point of CMYK data in the GUI and the profile report
The display of the black point CMYK and Lab values has been corrected so that the values in the user interface match the values of the profile report.
Batch Overview
- Numerical sorting of the Index column
In addition to sorting the columns by creation date, type, name, etc., it is now possible to sort the Index column numerically correctly.
General

Improvements and Bug Fixes
DeviceLink Linearization
More Linearization Options and new channel-specific Custom ink limitations
With CoPrA 11, the flexibility in creating a DeviceLink Linearization has been greatly improved. Adding a dedicated Ink Limitation mode with the option to set Custom ink limits allows for user-defined, channel-specific ink limiting. The previous options with fixed ink limits have now been replaced by a more flexible alternative.
In order to provide flexible assignments of the available Ink Limitation modes to the various calculation modes, these previously fixed settings have now been separated and extended.
Linearization Options
Now, there are four Linearization Options. The Ink Limitation mode and the Maximum Values are new.
Calculation
The Calculation mode defines the method for calculating the colorimetric linearity. The available standard methods can be customized and saved.
When selecting a Calculation mode, a suitable Ink Limitation mode is automatically set. However, the preselected Ink Limitation mode can be set to Custom which then allows user-defined ink limits to be set. The previous calculation modes with fixed predefined ink limits have been removed.
Ink Limitation
There are three different Ink Limitation modes to choose from:
Maximum: No limit is applied, the output per channel is 100%.
This is the preselected default Ink Limitation mode for the calculation modes Linearization according to G7 (CMYK only) and Linearization according to G7 (CMYK) and ISO 20654 (spot colors).
Automatic: The applied ink limit is calculated based on the measurement data and is displayed grayed out in the Maximum Values section for each color.
This is the preselected default for the Calculation modes ColorLogic Default (Colorimetric Linearization), Linearization according to ISO 20654 and Ink Splitting (ColorLogic Default).
Note: Automatic is the default Ink Limitation mode for the Ink Splitting (ColorLogic Default) calculation mode and cannot be changed.
Custom: Based on the automatically calculated values for the ink limits, these values can be changed in the corresponding input fields of the Maximum Values section.
Maximum Values: Displays the maximum values of the individual channels and if activated, allows these values to be changed. Please note that the maximum used values of the light (ink splitting) channels are also displayed.
All changes and limits are immediately calculated and applied to the Calculated Curves view, which means that the curves are based on the currently selected settings that will be applied in the resulting Linearization DeviceLink profile.
The linearization settings of CoPrA10 and older (up to CoPrA8) are compatible with CoPrA11. This does not apply vice versa.
Profile Manager
Redesigned Profile Filter and improved Profile List
The Profile Filter section has been redesigned to be more compact, leaving more space for the Profile List.
New column sort function and new Date column in the Profile List
All columns can now be sorted by clicking on the column title. A new addition to the Profile List is the Date column, which displays the creation date of the respective profile.
Major improvements to the Gamut tab
The Gamut view has been revised and enhanced allowing the comparison of two profiles in the 3D view and up to three profiles in the 2D view. The gamut view has also been enlarged.
2D View
Lightness: The Lightness slider has been removed; it is now possible to change the lightness with the mouse wheel or by entering the value directly in the input field.
With the ab-Projection checkbox, the entire gamut can be shown as a flat projection on the ab plane.
Profile Selection: The gamut of the Selected Profile can be compared to the gamut of up to two Comparison Profiles selected in the Profile Selection. These comparison profiles can either be set via the context menu of the profile list or via the Load option of the context menu that can be accessed by right-clicking the area next to Comparison Profile 1 and 2.
The color of the outlines of the individual profiles can be changed by clicking the color field and using the tools provided.
3D View:
Gamut Zoom: The Zoom slider has been removed; it is now possible to change the zoom factor with the mouse wheel, a shortcut (macOS: CMD+ / CMD-, Windows: STRG+ / STR-) or by entering the value directly in the input field.
Profile Selection: The comparison profile can either be set via the context menu of the profile list or via the Load option of the context menu of Comparison Profile 1 (accessible by right-clicking in the area next to Comparison Profile 1).
Since only two profiles can be compared in the 3D gamut view, Comparison Profile 2 is grayed out here.
In the 3D view, Comparison Profile 1 is displayed in a semi-transparent white color.
Context menu of the Gamut view
A context menu that provides additional viewing options can be opened by right-clicking on the gamut view. The Grid, Axes and Axes Labels can be switched on and off here. When analyzing Sample Data, the sphere size can also be increased or decreased using a key combination (macOS: Option+ / Option-, Windows: ALT+ / ALT-). For a better display of the Sample Data, the gamut view can be switched between a Gamut Surface view and a polygonal gamut grid view.
The options last used in the Gamut view are saved and applied again when CoPrA is restarted.
DeviceLink Profiling
New 3D conversion Gamut view in DeviceLink Profiling
A new function in the DeviceLink tool is the option to switch between Curves and Gamut view, as in the Printer Profiling tools. The gamut view reflects the conversion between the source and target profile.
Curves: Visualizes the effects of the selected Color Generation and Black Point and TAC settings of the selected target profile.
Gamut: The Gamut view shows changes to the gamut shape immediately when settings are changed and provides a real-time preview of the expected conversion between source and target profile. All settings, e.g. rendering intents, exceptions, black point, etc., are considered and displayed in the gamut view.
Note: Below are some examples of the Gamut preview for a DeviceLink creation with the profiles ISOnewspaper26v4.icc and CMYKOGV.icc with different settings. The gamut shows the conversion between these two profiles.
Calculating the gamut preview can take some time due to the complexity of this process. While the gamut preview is being updated, the message "The gamut is calculated..." is displayed. However, further settings can be made during the calculation.
In addition, the Gamut Volume is calculated and expressed in Lab units using absolute colorimetric rendering intent which allows finding the settings that produce the largest gamut (highest number) easily.
DeviceLink / Printer Profiling
Show Measurements of underlying data in Gamut view
Another new feature is the option to view the Measurements of the underlying data in the Gamut view.
When creating printer profiles, this allows analyzing the patch distribution within the profile gamut so that the measurement data can be optimized in ColorAnt beforehand if necessary.
When creating DeviceLink profiles, the measurement data of the target profile is displayed in comparison to the DeviceLink conversion. This allows a comparison to be made between the maximum color space of the target profile and the actual conversion in the DeviceLink profile depending on the selected settings.
Context menu of the Gamut view
A context menu that provides additional viewing options can be opened by right-clicking on the gamut view. The Grid, Axes and Axes Labels and the Measurements of the underlying data can be switched on and off here. The sphere size can also be increased or decreased using a key combination (macOS: Option+ / Option-, Windows: ALT+ / ALT-). For a better display of the Measurements, the gamut view can be switched between a Gamut Surface view and a polygonal gamut grid view.
The options last used in the Gamut view are saved and applied again when CoPrA is restarted.
Colorants Information included in the profile reports for CMY and CMYK color spaces
The colorants information in the profile reports for printer and DeviceLink profiling is now also available for CMY and CMYK color spaces in addition to the still available information for xCLR color spaces.
Printer Profiling
Black Start option for the Multicolor Mode “Generate Separations with sparse inks”
For color spaces from 5CLR up to 15CLR it is now possible to define the Black Start when using the Multicolor mode Generate Separations with sparse ink. This allows the black channel to be controlled to avoid the use of black ink in the highlights if required.
Save ink with the new setting Sparse Ink
To simplify the use of the Multicolor mode Generate Separations with sparse ink, there is a new setting Sparse Ink available.
Minor adjustments to Viewing Conditions
Minor user interface adjustments have been made here.
DeviceLink Editing
Improved patch selection and analysis
When moving the mouse pointer over a color patch, it is highlighted by a black or white frame and the source and target color space values are displayed. A left mouse click captures the color patch, making it easier to check whether and to what extent it is affected by an exception.
Exceptions which are unavailable are grayed out. This may be the case when a dependency between exceptions exists, or when exceptions are not relevant for a specific color space.
Image Conversion
New Toggle Preview for color management workflow comparison
With the adjustable overlay tool, you can define a resizable comparison area of the image preview in which you can compare the image with the target profile using the defined color management workflow from the source profile via the rendering intent.
The Toggle Preview button switches the entire visible preview area so that either the image rendered with the Source profile, or the Target profile is shown.
To change the size of the comparison area, the adjustable overlay tool can be picked in the opposite corner of the selected preview, i.e. in the bottom right corner of the Source profile preview and in the top left corner of the Target profile preview.
New image preview scaling options
New preview scaling options have been added to the Image Conversion preview area.
The Fit Image option scales the image to the maximum size of the full image in height or width, depending on the image orientation.
Fit Width scales the image to the maximum width (recommended for images in portrait format).
Fit Height scales the image to the maximum height (recommended for images in landscape format).
Batch Overview
The optimized Batch Overview simplifies the further processing of profiling jobs
The Batch Overview window has been completely revised. The icons present in CoPrA10 and older have been removed and all post-processing options have been moved to a context menu. This provides a clearer overview and a more efficient handling of subsequent tasks.
Parent Job with Index numbers
Different processes within a profiling job have been combined under a single higher-level parent job with a unique Index number. The profile name is shown in the column Type of this parent job.
For example, the printer profiles created, the profile reports, the preview profiles and the Multicolor variants are listed under the parent job. Additional information such as color space and profile types can also be found in the Type column.
Additional Columns:
The respective file names and the number of profile variants are displayed in the column Name.
The Status shows the current processing progress of the job, i.e. whether it is currently being created or has already been completed.
Progress shows the progress of parent jobs and individual jobs as a percentage.
Follow-up processing via Context Menu
Additional tasks can be assigned to each job within the parent job using the context menu. For example, additional variants can be calculated that were not yet calculated in the first step.
Depending on the type of the selected job, corresponding options are available in the context menu.
