Profile Assignments

Create and manage SmartLink settings

Profile Assignments function 

Profile assignments can customize ZePrA’s SmartLink function. Standard DeviceLinks, house standards, or custom profiles can be assigned to configurations automatically and used for conversions.

Create and manage profile assignments

Activating the SmartLink function

  1. Activate the Apply SmartLink checkbox in the Images/Vectors tab or select the SmartLink entry from the drop-down menu Conversion Method in the Document/Target tab.


  2. Activate the Apply Profile Assignments checkbox in the Profile Assignments dialog to use the assignments defined in the table.

  3. The SmartLink function can be used to create configurations with Auto Setup. SmartLink primarily uses profiles from the table of the Profile Assignments tool. If no suitable profiles are found in the table, a DeviceLink calculation is automatically performed on-the-fly based on the selected source/target/document profiles.

Create or edit profile assignments

To create or edit SmartLink profile assignments, use existing Device Links or standard profiles. 

To add new profile assignments, click New at the bottom of the window and select the DeviceLink profile directly from the DeviceLink Profile drop-down menu.

To edit existing profile assignments, open the Edit Profile Assignment window by double-clicking the particular assignment.

Change profile assignment settings

If the DeviceLink profile contains a PSID tag (e.g., ColorLogic profiles), the source and target profiles are automatically displayed in the Source and Target Profile drop-down menus. Alternatively, select a combination of Source and Target Profile and a Rendering Intent. The DeviceLink Profile matching this combination of color spaces can be selected from the drop-down menu.

To ensure that the selected DeviceLink profile is used, both the source and target profiles of the DeviceLink and the rendering intent must comply with the settings under Configurations. If the DeviceLink profile is to be a priority, regardless of the rendering intent selected under Configurations, then select the entry All in the Rendering Intent drop-down menu under Edit Profile Assignment. The DeviceLink will be used with all rendering intents.

Apply to specifies whether a DeviceLink is to be applied to vectors and images, only to vectors, or only to images. This allows a vector DeviceLink profile to be selected for a color conversion (e.g., AdobeRGB to ISO Coated V2) that converts primary and secondary colors to 100% of the corresponding CMYK values, while a different DeviceLink can be selected for images for which such a conversion is not desired.

Delete removes individual profile assignments, Delete All removes all table entries.

Note: When jobs are being processed, ZePrA displays in the status bar of the jobs and queues Overview whether DeviceLink profiles are calculated via SmartLink in the background. In the Job Properties, you can also view the color spaces and whether a DeviceLink profile was derived from the Profile Assignments or whether SmartLink created it on-the-fly.

ZePrA | Overview


View Queues, Pending Jobs and Processed Jobs

Jobs and Queues Overview

The Overview window is divided into three sections: Queues, Pending Jobs and Processed Jobs.


ZePrA Configurations are associated with queues, however, the queue and its configuration are managed separately. Configurations can be assigned to Queues or changed anytime. The configuration assigned to a queue is displayed in the Configuration column.

To quickly access a queue’s hot folder, right-click a queue and select Open Folder in the context menu.

Stop or Start a queue via right clicking.

The priority order for queues can be controlled for file processing. Change the Priority of any queue by right-clicking on the queue to change the default setting Normal to High or Low.

Queues that are inactive or invalid are highlighted in orange. Incorrectly configured queues may be highlighted due to incomplete entries or missing profiles.

The job lists in the lower panes of the window show which jobs are still pending and which have been processed.

If errors occur when processing files, or if ZePrA detects non-supported file types, they are highlighted in red in the list Processed Jobs. If warnings occur during processing, file processing continues and the job is highlighted in yellow and labeled with a warning. Warnings show what action to take.

The Queues list can be sorted by ID, file Name, Configuration, Jobs  and Status. Clicking on the ID column places the most recently processed job at the top, while clicking on the Status column sorts the files according to their Priority.

The Notes entered in the Configurations and Queues dialogs are displayed in ZePrA’s main window in the Queues list. The Notes column allows to quickly find queues based on cleverly selected keywords, such as customers, printers, media types, or other special properties.

Processing of queues can be started or stopped with the Start and Stop buttons on the bottom right of the window. The buttons are grayed out appropriately based on the queues status being active or inactive, e.g. they are grayed out for inactive queues.

Right-clicking on jobs under Queues opens a context menu where the following options can be chosen:

Starts the selected queue.

Stops the selected queue.

Changes the Priority of the jobs to be processed. Change the setting to Normal, High or Low.

Edit Configuration
Change the selected configuration settings.

Edit Queue
Edit the queue settings.

DeviceLink Iteration
Starts the DeviceLink Iteration Wizard for the selected configuration.

Open Folder
Opens the queue’s folder (hot folder).

Add File to Queue
Select the file to be processed, it will be imported directly into the Input hot folder of the queue and processed immediately.

Add File(s) to Queue and hold
Allows you to add files to the selected queue and hold a job, e.g., to temporarily edit the configuration settings without permanently changing the configuration, or to add Job Control Files (XML or JSON) with the processing parameters for the selected job. Several files can be added at once. For more information, see Temporary Change of the Job-specific configuration settings.

Opens the Delete Queues dialog.

Delete Configurations: Deletes the Configuration associated with the queue.

Delete Folders: Deletes all subfolders associated with the queue. The Base Folder of the queue is not deleted.

Delete empty Parent Folders: Deletes all subfolders and the Base Folder of the queue.

The table shows the files and folders which were selected for deletion.

Type: Indicates whether it is a queue, a configuration or a folder. For folders, the number of files contained is also displayed.

Name: Shows the names of queues, configurations and folders. For folders, the whole path is displayed.

If all checkboxes are unchecked only the queue will be deleted. In that case, the configuration and all folders will remain on the hard drive.

Export: Configurations can be exported from within the Overview window. Select the Queues that contain the configurations to be exported, open the context menu and select Export. This opens the Export Environment window, in which the configurations of the previously selected Queues are preselected. A manual search for the desired configurations in the Export Environment dialog is not necessary.

Temporary change of the Job-specific configuration settings

Configuration settings can be changed temporarily on a job-by-job basis. Add File(s) to Queue and hold allows you to load and hold a job and temporarily edit the configuration settings without permanently changing the configuration.

Example: You are printing various jobs on a digital printer and most of the jobs are to be printed on cardboard, with your configuration in ZePrA defined for this purpose, but one job is to be printed on a different substrate. In both cases, the same configuration is used, but with different target ICC profiles. Instead of creating a copy of the existing configuration for this one job, you can use this feature to temporarily edit the configuration settings without permanently changing the configuration.

Note: Several files can be selected at once.


Right-click on the queue and select Add File(s) to Queue and hold from the context menu and select your file(s).

Processing of the selected file is paused in the Pending Jobs section. Right-click on the job and select an option from the context menu:

  • Hold Job pauses this one job without stopping the queue
  • Release Job starts processing the job with the given configuration, including a temporarily modified configuration or a Job Control File that has been attached to the job.
  • Modify Configuration for this Job opens the Edit Job Configuration window. Here, the configuration to be used can be selected and modified. All modifications apply for this job only.
  • Attach Job Control File allows to associate an XML or JSON file with the processing parameters for the selected job. In contrast to the typical behavior of the Job Control File, a possible job listed in the file is not taken into account and the file is directly applied to the job, which makes this option especially interesting for manual work.

Modify Configuration for this Job: Allows changing the base configuration to be used for the processing the selected job. By default, the configuration associated with the selected Queue is preselected. Select the checkbox Modify Configuration for this Job if additional changes in the configuration are required and click OK.

Modify Configuration for this Job: Opens a temporary copy of the selected Configuration in a separate dialog. Name shows the currently used configuration. The text in brackets indicates that this configuration is temporarily modified for the selected job.

Change the desired settings and optionally change the name of this customized job-specific configuration to make it easier to recognize later on.

Once you are done with your edits click Apply to confirm or Back to return to the original settings. In both cases the dialog will close and ZePrA will revert back to the
Overview dialog.

Release Job: Starts processing the job with the modified settings. Keep in mind that the edits will be applied to this one job only.

DeviceLink Iteration


Iteration can be necessary to achieve the best possible color match, especially when proofing. To apply an iteration, a special test chart must be converted with the desired color management settings of a given configuration, printed and measured. Based on the measurements the DeviceLink profile can then be optimized. After one to three iteration cycles, a closer match in terms of DeltaE values is achieved. This process is error-prone if done manually, however, it is easy to accomplish with the help of the DeviceLink Iteration Wizard, which guides you through each step.

Video Tutorial

Overview of the DeviceLink Iteration Wizard in ZePrA.


The iteration starts by selecting the configuration containing the DeviceLink to be iterated. This can be done in three different ways:

  1. In the Queues section of the Overview, select the queue and configuration you want to iterate. Open the context menu with a right click and select DeviceLink Iteration.

  2. Select DeviceLink Iteration from the Tools menu and search for the desired configuration in the Configuration drop-down menu of the appearing DeviceLink Iteration Wizard. You can use the same search and sort functions that you are familiar with from the Configuration drop-down menus elsewhere in ZePrA to find the configuration you are looking for.

  3. Open the desired Configuration in the Document/Target tab and click on the Iterate button at the bottom of the Conversion section.

The DeviceLink Iteration Wizard dialog consists of two tabs, the Current Iteration and the Archive tabs. The Current Iteration tab contains the actual iteration wizard and typically, if a configuration is selected that has not yet been iterated, the wizard is started directly there. The Archive tab contains all the iteration steps that have been carried out, including all the evaluation details.

Current Iteration

The wizard guides the user through the iteration process in these four steps:

  1. Create test chart to be printed
  2. Print and measure test chart
  3. View Evaluation Results
  4. Continue or end the iteration

Step One: Create the test chart to be printed

There are two possibilities to create the test chart. Either you use the included Default Iteration Chart, which of course is always optimized for the color space of the given configuration. Or, select your own reference file (TXT, CXF3, XML) of a custom chart under Custom Iteration Chart.

After that, define your measurement Instrument Settings. Various settings for the supported measurement equipment can be selected from the drop-down menu in the Measure Tool (the Measure Tool is included in ZePrA).

Note: ColorLogic ColorAnt users can create their own instrument settings optimized for their specific requirements in the Export Chart tool.

Click Save and choose a file format (PDF, TIFF or PSD) to create the test chart in the selected location. All color management settings of the configuration will be applied automatically.

Note: In some cases the creation of the chart may take some time, for example if the Conversion settings SmartLink or Device Profile are used in the configuration, as the wizard will then need to create a DeviceLink profile first.

After you successfully created the chart and the associated reference file, a message and a green check mark indicate that you can now proceed to the next step by clicking the Continue button.

Step Two: Print and measure test chart

The second step consists of two operations. First, the chart created in step 1 must be printed on the printer without color management settings. Then, after drying, the print must be measured. If the Measure Tool is to be used, simply click on the Measure button. You do not need to worry about the reference file and layout, as this is already preselected within the Measure Tool. Instructions on how to select your device and make measurements using the Measure Tool can be found here.

Note: Alternatively, you can use the previously exported reference file and measure your printed chart with a different measurement tool. Make sure that the measurements are saved in standard file formats that can be read by ZePrA, such as CGATS TXT, XML or CXF3. The external measurement files can be loaded using the Load button.

Once the measurement data has been transmitted from Measure Tool or loaded from external sources and it conforms to the printed chart a green check mark indicates a match and you can proceed by clicking Continue.

Note: When loading measurement data that does not match the chart layout or the corresponding patches in the reference file, you are alerted by a warning message and proceeding to the next step is not possible.

Step Three: View Evaluation Results

The third step shows the Evaluation Results of the measurements compared to the desired color conversion.

If all categories such as substrate, the maximum and average deltaE for all patches, etc. are within their limits they are marked green and the overall result is marked all right.

In a proofing case, e.g if an absolute colorimetric rendering intent was used in the configuration, the proof print is compatible with a Contract Proof according to ISO12647-7 and the wizard indicates this by a green check mark and a corresponding note text. A further iteration is then not required, hence the Don’t apply Optimization radio button is preselected.

However, the preselection can be overridden and another iteration cycle applied if the results are to be improved even further. To do this, select the Optimize DeviceLink and apply radio button and click Continue. Alternatively, apply the iteration later via the Archive tab.

If only a single category is displayed in orange or red in the table of Evaluation Results, the proof print is considered to be not okay and the validation has failed. In this case, a warning is displayed and it is suggested to apply an iteration to improve the result. The corresponding radio button Optimize DeviceLink and apply is then preselected.

By selecting Optimize DeviceLink and apply and clicking on Continue, an iterated DeviceLink is created on-the-fly and automatically entered in the configuration.

ZePrA checks for out-of-gamut colors and evaluates whether those colors can be improved. Color values that are displayed in red in the Evaluation Results and Report are considered to be out-of-gamut and their deltaE00 values can most likely not be improved. Nevertheless, an iteration can slightly change the rendering of out-of-gamut colors, for example, to correct hue errors when colors are far from the desired hue. Color values that are displayed in orange, however, can be improved with further iteration. If there are only red values left, ZePrA informs, that further iterations are of no use and preselects the Don’t apply Optimization radio button. If, however, there are orange values left, these can be further optimized and ZePrA suggests Optimize DeviceLink and apply.

Step Four: Continue or end the iteration

The fourth step concludes the iteration cycle. Here, there are three options to choose from. Based on the previous results, the wizard already preselects a logical option for you to follow:

  1. Optimize DeviceLink Profile again: Runs another iteration cycle, for example to check whether a previously iterated DeviceLink successfully passes the evaluation. If you select this radio button and click Continue, a new iteration cycle starts with step 1 and the creation of a new test chart to be printed.
  2. View the evaluation results in the Archive tab: If you have already completed several iterations or would like to see the evaluation results once more, select this option. When you click Continue, the Archive tab opens with the last iteration step highlighted.
  3. Close this dialog: If the evaluation results are all right or if you want to end the iteration process you can simply select Close this dialog and by clicking Continue the iteration is ended.


All data created during the iteration - such as test charts, reference data and measurement data, as well as the report - are stored in an internal database in addition to the save location defined by the user.

Therefore, if data is deleted from the save location it can still be restored from the internal database any time via the Archive tab. Users can stop an iteration process and even close the DeviceLink Iteration Wizard dialog at any time and can revert back to the last completed step with the help of the Information stored in the Archive.

The Archive tab shows all iteration steps and evaluation details. The History table contains a list of all iterations, with the active iteration highlighted. More information for the selected iteration step is displayed under Details.

The columns of the History table show the iteration step number #, the maximum DeltaE00 value dE00 (max), the average DeltaE00 value dE00 (avg), the Status of the selected iteration step and some Information about the iteration process itself, such as Optimization applied, when the measurements done from the printed test chart have actually been used to create an iterated DeviceLink, or Evaluation measurement, when the measurements have been used for evaluation only and have not been used to create an iterated DeviceLink.

In addition, the iteration process (being performed in the Current Iteration tab) can be discontinued, which is indicated with various messages such as Next step: save chart, Next step: measure or load data, Next step: Evaluate.

Right clicking on an iteration step in the History displays a context menu with the following options:

Save Chart: Exports the test chart into a file selected by the user. The test chart is not newly created but only copied from the internal database. This implies that the file selection only supports the file type initially chosen by the user.

Save Reference Data: Exports the reference data that belongs to the test chart into a file selected by the user.

Save Measurement Data: Exports the measurement data into a file selected by the user.

Save Report: Saves a report containing all Details displayed on the right and the full information about each measurement patch. This is useful to identify colors with the highest or lowest deltaE values, or colors which are out of gamut. The report is explained in more detail below.

Revert to state before: This is only available for iterations with the status applied. Reverts back to the state before this iteration, giving the previous iteration, if any, the applied state. The status changes to evaluation measurement. All subsequent items are deleted.

Revert to state after: This is only available for iterations with the status applied. Proceeds to the state after this iteration step, making it the active iteration. The status of a next iteration, if available, would be evaluation measurement. All subsequent items after the next iteration are deleted.

Apply Optimization: This is only available for iterations with the status evaluation measurement. It can be used for evaluation measurements that have not been applied in the iteration process itself. Use this option if you want to apply an iteration later on.

Evaluation Results

The Evaluation Results shown under Details are always the evaluations of the previous step. This means, if an iteration has been applied in step 1, the evaluation results shown under Details for the selected step 1 are the values before the iteration has actually been applied. Therefore, in order to see the results of the first iteration a second step is necessary. The evaluation results shown for that second step are actually the iteration results of the first iteration step, and so on. This offers the possibility to use the results of an iteration itself for a second iteration. But again, another measurement step is needed to find out if this iteration actually improved the result.

Evaluation measurements for the different Categories are shown according to the proof evaluation tolerances defined in ISO 12647-7. They can even be regarded as proof evaluation when an absolute colorimetric rendering intent has been used in the configuration. The values shown in the table can assume three different colored states that are green, orange or red. Values shown in green are within the Limit and therefore all right. Orange values are outside the Limit but can be improved by iteration. Red values are outside the Limit and cannot be improved. This is mostly the case if a source color can’t be reproduced in the target color space because it is out-of-gamut. An overall statement of the accuracy of the rendering is given below the table. A green check mark indicates that the color conversion is within the limits, whereas a red cross indicates that it is not.

Special cases arise if the rendering intent used in the configuration is not absolute colorimetric. In case of relative colorimetric or perceptual rendering intents the reference Lab values used to iterate the conversion need to be calculated from the initial DeviceLink profile. The measurements are then compared to those rendering intent specific reference Lab values. The iteration is still using the tolerances from ISO 12647-7 for the analysis of the iteration accuracy. However, since this conversion is not a proof print, a different statement results for the overall iteration accuracy compared to the iteration result with an absolute colorimetric rendering intent.  

The Report

By right-clicking on an iteration step in the left table, a report can be created for this step. The report can be saved in various formats such as PDF, HTML, XML and TXT. The PDF and HTML formats are the most common versions for end users, while the other formats are more intended for automation and usage in other systems such as a MIS (Management Information System). 

The report contains all displayed Details and the complete information for each measuring patch. This is handy for identifying colors with the highest or lowest DeltaE values or colors that are out-of-gamut. A Legend explaining the color highlighting in the DeltaE column is shown at the bottom of the last page of the report.

Pending Jobs

The list Pending jobs shows the Job-ID, the file name, the queue and the status of the queue. It can be sorted by ID, Name, Queue and Status. Clicking on the ID column places the most recently processed job at the top, while clicking on the Status column places the files with errors and/or warnings at the top.

The Status column provides information about the progress of file processing. Displays the processing step (such as SmartLink calculation or ink saving calculation) and the progress in percent.

Right-clicking on a job under Pending Jobs opens a context menu containing the following options:

Change the priority of the job to Normal, High or Low.

Deletes the selected job.

Processed Jobs

The list Processed Jobs at the bottom of the window shows which jobs have been processed.

If errors occur when processing files, or if ZePrA detects non-supported file types, they are highlighted in red. If warnings occur during processing, file processing continues and the job is highlighted in yellow and labeled with a warning. Warnings show what action to take.

The list shows the Job-ID, the file name, the queue, the status and the date. It can be sorted by ID, Name, Queue, Status and Date. Clicking on the ID column places the most recently processed job at the top, while clicking on the Status column places the files with errors and/or warnings at the top. By right-clicking on the header of the list, the columns ID, Queue, Date, and Processing Time can be enabled or disabled. The Processing Time of the job is displayed in seconds.

Right-clicking on jobs under Processed Jobs opens a context menu containing the following options:

Screen Preview
View a screen preview with color management of the selected job.

Show Job Properties
Opens the Job-Report which contains properties of the selected job. More information on job properties can be found in the section Show and Save Job Properties below.

Save Job Properties
Saves the Job Report as PDF, HTML, TXT or XML file.

Repeat Job
Allows to process a processed job once again using the same configuration without the need to open the hot folder.

Restore Configuration
ZePrA allows restoring the configuration of a previous job in order to reprocess a file. As of ZePrA 7, the configurations of all jobs are saved and kept for future re-prints.
When to restore a configuration: A customer requests a reprint of a job and requires a similar or even identical color appearance previously printed. If that configuration has not been saved, or has been changed since, it is lost and it might be difficult or even impossible to remember the ZePrA settings used for that job.
Restore Configuration allows restoring a previously used configuration.

Spot Color Iteration
Starts the Spot Color Iteration Wizard with the spot colors of the selected file and the matching configuration.

Open converted File: Opens the converted file in its standard application (e.g., Adobe Acrobat for PDF files).

Navigate to converted File: Opens the folder containing the converted file.

Deletes the selected job.

ZePrA’s Search Feature

The search function can browse through the sections Queues and Processed Jobs to search for the following criteria:

  • File names
  • Queue names
  • Configuration names
  • Parameters in configurations: Names of ICC profiles, names of spot color libraries
  • Notes entered for configurations and queues
  • Tags

To use the search function, enter the search term in the text field with the magnifying glass icon.

  • The search is not case sensitive.
  • Entered text will be applied automatically after a few seconds. To start the search immediately click Apply.
  • To find information, entering part of the search term will suffice, for example to find the queue ‘Normalize_GRACoL2006_Coated1v2’ entering the initials ‘gra’ is sufficient.
  • The results of the search are displayed in the windows Queues or Processed Jobs, respectively.
  • Deleting the input text or clicking on the X in the search field will immediately display all queues again.

In the Processed Jobs section, limit the search to a specific date range. This is useful to check how many and what kind of jobs have been completed in the searched time period (for example for a specific customer).

Search jobs by a defined range or in a period of the last few days, weeks, months or years. To do so, select one of the three options from the drop-down menu:

  • All Jobs: Searches all jobs. This is the default setting in ZePrA.
  • Recent Jobs: By choosing this option a number input field and a drop-down menu becomes available. In the drop-down menu choose whether to search for jobs in the last few days, weeks, months or years. Entering a number in the number input field will specify the time period.
  • Jobs by Date Range:
  • By choosing this option two date input fields (Mac) or two date input fields with drop-down calendar (Windows) become available. In the first input field (or calendar) enter the ‘from’ date, and in the second field the ‘to’ date. If a date is entered in the first field (or Calendar), only records from this date onward will be searched.

The Notes that have been entered in the dialogs Configurations and Queues are shown in the main window of ZePrA in the list Queues. The Notes column allows to quickly locate queues based on relevant keywords, for example; customers, printers, media types or other special properties.

ZePrA | Edit Spot Color

Edit Spot Color

Create and edit spot colors

Editing and Measuring Spot Colors

  • Individual new spot colors may be entered as solid tones or gradations via the New button under Spot Colors from selected Libraries and the Edit Spot Color dialog will open. Spot colors as CxF/X-4 data are fully supported.
  • Name: Enter the name of the spot color. The name should be written as in the PDF document since it is used as an identifier and therefore crucial for a successful automatic conversion.

Note: If separate libraries are created for different substrates or printing processes, identical spot color names can occur in several libraries but will be associated with different measurements. Make sure to select the correct library for the color conversion in the configuration to avoid problems.

Editing a Spot Color

  • Use the checkbox Non Printing Color to define whether the indicated name of the spot color corresponds to a non-printing color (die-cutting marks, braille, coatings, etc.). Activating Non Printing Color will make the necessary settings automatically. Close by clicking on OK.
    Note: In modern PDF files non printing areas can also be defined bywith processing steps. Read the explanation about PDF Layers for more information.
  • Printed on White Background (Substrate) and Printed on Black Background (Process Black): If the spot color is available as print on white or black backgrounds, enter it by manually measuring or by importing measured values for further processing.
  • Use Template: To process a ‘true’ spot color, indicate the Solid Tone for the 100% value of the spot color. For complete tints, select a template with either three steps (3 patches: 0%, 50% and 100%) or with eleven steps (11 patches in 10% increments). Alternatively, Import a spot color that has already been measured and is available as measurement file.
  • Custom: If a printed wedge with tints of the spot color does not correspond to either of the predefined templates, click Add to open the Additional Tone Values which allows to enter gradations of the wedge as percentage values. Seperate the percentage values by spaces and confirm with OK.
  • The personal wedge is marked as Custom and can be saved for later use with Save as Template.
  • There are three ways to define color values: Enter the Lab values for each gradation manually, select Measure to use the Measure Tool supplied with ZePrA, or select Import to load existing measurement files.

Note: It is recommended to print a wedge of the spot color directly onto the respective substrate as well as a second wedge of the spot color as an overprint with the black process color (black must be printed first) using the correct printing conditions and to measure them spectrally in ZePrA. This will allow ZePrA to perform high quality conversions for the solid tones, the gradations and the opacity, taking dot gain into account. Compared to Lab values, spectral measurement data can improve the simulation of overprinting spot colors.

  • Click on Measure to open the Measure Tool. For further information read Measuring Spot Colors with the Measure Tool below.
  • Once the measuring is complete, the measurement can be transmitted to ZePrA by clicking the Transmit button. This will close the Measure Tool and the Edit Spot Color dialog reappears. Click OK to add the measured spot color to the color library.

Opacity indicates how translucent or opaque a color is. A spot color is fully transparent when the value is set to 0% and completely opaque with a value of 100%. When the opacity value is changed manually, the spot color has a custom opacity.

Reset: Removes the custom opacity from the spot color. The Reset button is enabled if the spot color has a custom opacity, otherwise it is disabled. If the spot color has no custom opacity (Reset button disabled), the displayed opacity value is updated whenever a relevant measurement value (e.g. measurement on black) changes.

Note: ZePrA will automatically calculate the opacity of measured values on black backgrounds, and use the opacity values for the color conversion of spot colors. Information from the ink manufacturer regarding the opacity of the spot color can be entered directly as a percentage, measurements on a black background are not required. Without any opacity information ZePrA will assume the spot color to be fully transparent at 0%.

Note: The Information table under Spot Colors from selected Libraries indicates whether a spot color in the library consists of a solid tone or of tints and whether the color values are based on spectral or Lab data. The opacity of the spot colors is shown as well, if available. Color values can be edited by double clicking on a spot color in the table. Delete, Cut, Copy and Paste are accessible using the right click context menu. Colors can be moved to another library by Cut and Paste. To do so, select the color(s) to be moved, right click and either Cut or Copy. Then select another Library, so that its colors appear in the table under Spot Colors from selected Libraries, right click and Paste.

Measuring Spot Colors with the Measure Tool

Some measuring instruments allow to select the measuring mode (M0, M1 or M2). Select the mode that fits the measuring requirements, then select the measuring mode for the wedge layout and press the Measure button on the instrument.

Note: Barbieri measuring instruments are optimized for test chart measurement therefore single patch measurement is not available.

Once the measurement is complete, the measured color appears in the Measure Tool. The measurement data can now be transmitted to ZePrA by clicking Transmit. Saving the measured values in the Measure Tool is not required.

The Measure Tool is part of ColorAnt and included in ZePrA. If it has not been installed on the computer, the Measure button is not available in ZePrA.

The following measuring instruments are supported by the Measure Tool:

  • Barbieri Spectro LFP
  • Barbieri Spectro LFP qb
  • Barbieri SpectroPad
  • Konica Minolta FD-7
  • Konica Minolta FD-9
  • Techkon SpectroDens (Windows only)
  • Techkon SpectroPad (Windows only)
  • X-Rite eXact
  • X-Rite i1iO
  • X-Rite i1Pro 1 (without XRGA)

Connect the measuring instrument to the USB port of the computer and select the appropriate wedge from the drop-down menu Use Template. Then click the Measure button in the Edit Spot Colors window in ZePrA. The Measure Tool will start and the rest of the process is completed within the Measure Tool software.

If a solid tone is selected, a single color patch is preselected for the measurement. If a step wedge is selected, the layout of the wedge selected in ZePrA is displayed. Under Selection, select the measuring instrument connected to the USB port from the drop-down menu. Click Connect and follow the instructions. More information about measuring can be found in the ColorAnt online help.

In single patch measurement, only one color is measured and transmitted at a time. Either click Transmit or re-measure if the measurement was faulty or unsuccessful.

Manage libraries and edit spot colors

Spot Color Libraries


ZePrA’s spot color module allows management of spot colors and spot color libraries efficiently. Select the tool Spot Color Libraries from the sidebar to access the window Manage Spot Colors.

Here you can create, add, view and customize libraries. Spot colors can be edited, imported or measured. For example, spot colors from color fans can be measured with a spectrophotometer or Lab values can be entered manually. Furthermore, color tables with spot colors can also be imported. Supported formats are Named Color ICC profiles, Photoshop ACO color tables, Adobe ASE color tables (from InDesign or Illustrator), text files in CGATS format or CxF files, such as CxF/X-4.

X-Rite Pantone Color Manager color tables support Named Color ICC profiles, CxF files (there are current Lab values, but no spectral values for Pantone solids), and CGATS-compliant text files. Import your PantoneLIVE color fans stored in the cloud by clicking the PantoneLIVE button.

Note: PantoneLIVE® from X-Rite is a cloud-based solution for the digital storage of spectral spot colors. To use PantoneLIVE, licenses are required for the ZePrA spot color module and X-Rite’s PantoneLIVE module. You need to unlock your licenses for use in ZePrA under My X-Rite. See PantoneLIVE to learn how to activate your licenses.

Both lab and spectral color values are supported; however, spectral measurement data is preferred as it provides the best results internally.

Edit Spot Color


A spot color library can contain a multitude of different information in just one library, such as the full tone, tints printed on a substrate or black, spectral or Lab measurements and opacity values.
All available libraries and the number of spot colors of a library are listed under Libraries. Additionally, the revision number and expiration date of PantoneLIVE libraries are displayed (with the PantoneLIVE icon).

After double-clicking on the selected library the spot colors will be shown in the lower part of the window. In order to improve the performance – especially with extensive libraries – spot colors will only become available when they are used for the processing of jobs or by double-clicking on a library.

The spot color table shows the Name of each spot color and additional Information such as the data type (Remission or Lab) Solid tone or Tone values, or Opacity information (custom or calculated).

The search function can be used to find specific spot colors quickly. Spot color libraries can also be searched for Lab values. If the search text is of the form “L a b Lab” (e.g. “51 7 -61 Lab”), ZePrA searches for spot colors matching the specified value. Since exact matches often fail due to rounding and non-precise input, a tolerance is applied.

Note: PantoneLIVE libraries are protected and in ZePrA they can not be edited, extended or removed. With PantoneLIVE, Pantone spot colors and libraries can be accessed directly from ZePrA.

Import spot color libraries
  1. Select the tool Spot Color Libraries from the sidebar.
  2. Import existing color tables containing many spot colors by selecting Import under Manage Spot Colors. The formats supported by ZePrA include ACO (Photoshop color tables), Adobe ASE, TXT (text files in CGATS 1.7 format), CxF (Color Exchange Format 3), CxF/X-4 and Named Color ICC-Profiles.
  3. To create a library from scratch using printed samples, click New, give the library a name and then click New on the lower right of the dialog to open the Edit Spot Color dialog. Each added color will appear in the selected library. For more information on how to measure or edit spot colors see Edit Spot Color.

Note: ZePrA does not provide spot color libraries with a new install. To obtain spot colors from some applications export Adobe Photoshop color tables with Lab color values as ACO files or Adobe InDesign/Illustrator files as ASE. Color tables of the X-Rite Pantone Color Manager can be saved as Named Color ICC profiles or as CxF file (provides current Lab values but no spectral values for Pantone full primaries) and CGATS compliant text files. Another source for spot colors is the PantoneLive eco system. The use of PantoneLIVE libraries requires the corresponding access data and an X-Rite license.

Export Spot Color Libraries from ZePrA

Spot color libraries can be exported. When clicking Export the supported file formats (CCF, ACO, ICC, TXT, CxF) for saving the library are displayed. Note that only the ZePrA internal CCF format allows saving all information that may be in a library. Use the CCF format to exchange a library with another ZePrA installation on another computer. The other more common file formats are mainly included for exchange with other applications. A warning appears for other file formats.

Export Spot Colors from ZePrA

There are three ways to Export spot colors:

  • In the upper Libraries panel an entire library with all colors can be exported.
  • In the panel below (Spot Color from selected Library) a single color from a library can be selected and exported.

  • In the Edit Spot Color window a single spot color can be exported, too.

  • PantoneLIVE libraries and single colors cannot be exported.

When clicking Export the supported file formats (CCF, ACO, ICC, TXT, CxF) for saving the library or a single spot color are displayed:

  • Only ZePrA’s internal CCF format allows saving all information contained in a library. Use the CCF format to exchange a library with another ZePrA installation on another computer.
  • Use the CxF format to save CxF/X-4 compatible files. A notification message shows which CxF/X-4 compatibility level has been exported depending on the data (X-4a, X-4b, full compatibility).
  • The other file formats are included to exchange data with other applications. However, the exchange is limited as not all data of a library can be exported using these formats. A notification message indicates which data can be lost when using the selected format.
