Previewing PDF and image files

Previewing PDF and image files

ZePrA’s Screen Preview displays a true color representation of files processed via queues on the monitor, with overprinting elements and transparency effects displayed correctly.

How to display a Screen Preview

  1. Open the Overview from the sidebar.
  2. Right-click a job in Pending Jobs or Processed Jobs to open the context menu.
  3. Choose Screen Preview.

  4. Your file will open in a new window.

  5. The colored symbol in the title bar can be used to access and adjust the color management settings for the screen preview. The preview is displayed according to these settings.

Simulation Profile: The colors are rendered to the monitor profile using the selected simulation profile. By default, the output intent that was embedded into the processed file by ZePrA is used. It is displayed in brackets. This setting is similar to the output preview of Adobe Acrobat.

Note: The Default Profiles and the checkbox Prefer embedded Profiles are only relevant if the Simulation Profile differs from the color space of the file.

Rendering Intent: A color conversion method (rendering intent) must be selected for the calculation. In addition to the standard ICC-Intents, there are four extra ColorLogic intents:

  • Black Compensation
  • Relative+ and Absolute+: Only have an effect if the black point in a matrix monitor profile is lighter than L* = 0, which makes the Screen Preview slightly darker, especially in the shadows, which usually results in a visually better match with a reference proof.
  • Relative Lightness: Is based on the Absolute Colorimetric intent with paper tone simulation. The brightness of the paper tone simulation is scaled to the maximum displayable brightness of the monitor, whereby the colorfulness of the paper tone simulation and the gray balance of the preview as a whole are preserved. This setting is useful if the absolute colorimetric preview provides a visually too dark display, as is often the case in newspaper printing.

If no simulation profile is available in the file (no profile is shown in brackets), select the appropriate profile from the drop-down list. Suitable rendering intents here are the colorimetrically based and the special ColorLogic intents.

The monitor profile stored in your system is automatically selected to display the screen preview on your monitor.

Click Apply to view the selected file with these settings and Save to save and close the window with these settings. The next time you open the window, these settings will be used again.

Note: In general, it is recommended to use a dimmable standard light box with a reference proof next to the monitor for visual comparison when selecting the correct screen preview intent.

Use of Multicolor profiles

Multicolor Profiles

Use of Multicolor profiles

ZePrA supports the use of Multicolor printer profiles and Multicolor DeviceLink profiles (RGB-to-Multicolor, CMYK-to-Multicolor and Multicolor-to-Multicolor).

Use of Multicolor profiles in PDF workflows

In ZePrA, Multicolor profiles can be used as document color space, as target profile or Multicolor DeviceLink profile for color conversion.

This is particularly important in the prepress stage for packaging printing when image data is available as RGB or CMYK files. You can therefore place RGB and CMYK image files directly in the finished document, create a PDF file from them and then convert this document in ZePrA to the required Multicolor color scheme for printing. Another interesting field of application is the printing of photo books in so-called Hifi-Color printing processes using 6 or 7 inks.

Note: A Multicolor license is required to use the Multicolor functions.

When preparing the data, ZePrA generates a so-called DeviceN PDF file in which each individual channel is named after the channel names of the Multicolor target profile. DeviceN has been the standard color definition within PDF for many years to describe spot colors for print production. This provides a high degree of compatibility with the proven spot color processing of common applications. The generated PDF files can usually be evaluated with current versions, for example of Adobe Acrobat Professional, in the separation preview and can be processed with current PDF workflow systems. It is also possible to place PDF files into and export them from current Adobe InDesign documents. ZePrA supports the PDF/X-5n standard, which enables the embedding of Multicolor profiles in PDF files.

By default, a configuration created with Auto Setup does not embed the Multicolor target profile in image data, but in the Output Intent of PDF files. In the case of a converted PDF/X file (for example, a PDF/X-4, -X-3, or -X-1a file), the color converted file is converted to a PDF/X-5n file.

Before using a Multicolor printer profile that you select as target color space in the Document/Target tab of the Configurations tool, or in case of a Multicolor DeviceLink profile, check that the channel names and Lab color definitions have been entered according to your specifications.

If the checkbox Embed into Output File is activated, ZePrA transfers the channel names and color definitions from the Multicolor printer profile selected as the target color space to the color converted PDF file.

If this checkbox is not activated, the channel names and color definitions are taken from the Multicolor DeviceLink profile. So make sure that the channel names and Lab color definitions in the target profile and DeviceLink profile are identical. The names of the color channels (Colorants) and the Lab color definitions can be adapted in CoPrA with the Profile Manager for each Multicolor printer and DeviceLink profile according to your specifications.

Depending on the used Multicolor profile, the contained channel designations and the subsequent workflow outside of ZePrA, we recommend that tests of the complete workflow be carried out in advance to ensure that everything runs smoothly.

Convert image data with Multicolor profiles

ZePrA supports PSB, PSD, TIFF and JPEG files when converting image data with Multicolor profiles. Since the current file format specifications (as of May 2019) do not support embedding Multicolor profiles in TIFF, JPEG, PSB and PSD files, you should disable profile embedding for image data conversion in the Document/Target tab. We recommend saving image data converted to Multicolor as PSB or PSD files in Photoshop and then processing them with ZePrA. Of course you can also place PSB and PSD image files converted with Multicolor target profiles by ZePrA in Adobe InDesign.

ZePrA distinguishes between the following cases when converting image data from Multicolor files (can be set under Configurations/Options/Image quality):

  • If the channel names of the Multicolor target profile are CMYK+X, a TIFF file will be generated provided that Preferred lossless Format is set to TIFF.
  • If the channel names of the Multicolor target profile are not CMYK, a PSD file is created.
    Note: TIFF only supports CMYK+X.
  • If the Compression Method is set to Automatic, an attempt is made to preserve the format or to generate a TIFF file. However, if a JPEG file or a non-CMYK Multicolor profile is present, a PSD file is created.
    Note: JPEG generally does not support Multicolor color spaces.

ZePrA and PDF Preflighting

ZePrA and PDF preflight


Check the following aspects regarding color with a PDF preflight:

Check number and type of color channels present in the PDF file

Extra spot colors may be required or unnecessary depending on the print job. The preflight allows you to determine whether the number and labeling of the color channels are appropriate for the print job.

Undefined spot colors can be processed using ZePrA’s spot color module. If the spot color module has not been licensed, spot colors can at least be converted using the alternate color space (PDF). This provides the same results as a preflight program. Further information on the spot color module can be found in the Spot Color Processing chapter.

Once the job has been processed in ZePrA, the spot colors occurring in the PDF file can be checked by right-clicking on the processed job in the Overview to open the context menu and selecting Show Job Properties to open the Job Report. This is particularly useful when not using an additional preflight program.

Check RGB or CMYK objects containing embedded profiles

For fully automated workflows that are running without additional approval by the customer, we recommend printers only accept pure CMYK PDF files that have correctly embedded profiles. For other data, we recommend to optimize them with ZePrA and then send a low-res CMYK soft proof to the customer for approval.

Note: A standard queue created with Auto Setup (Normalize and convert Colors to new Output Condition) that uses the SmartLink function optimizes all RGB, CMYK, and Gray objects of a PDF file by using DeviceLink profiles. Any embedded profiles are taken into account in the conversion. Alternatively, a standard queue can be duplicated to change the handling of embedded profiles (see next section Ignoring CMYK Objects with Embedded Profiles).

The profiles embedded in the PDF file can be checked after job processing by right-clicking on the processed job in the Overview to open the context menu and selecting Show Job Properties to open the Job Report.

Ignoring CMYK objects with embedded profiles

In some workflows, especially in print shops, it is common to remove embedded profiles from CMYK objects (images and vectors). It is often assumed that the profiles have been added incorrectly and will cause problems in a subsequent ICC conversion.

When the SmartLink function is not licensed, this procedure follows the default setting for Auto Setup queues. When the SmartLink function is licensed, embedded profiles are taken into account. SmartLink conversions, which preserve primary and secondary colors, as well as separation, ensure clean conversions.

If embedded profiles are to be ignored or the SmartLink function is not to be used – for example, in Auto Setup queues for normalizing and color conversion or for SaveInk applications – deactivate the corresponding checkboxes (Apply Embedded Profiles/Intents or Apply SmartLink) in the Images/Vectors tab. This ensures that embedded CMYK profiles are not used. Instead, select Same as Document Color Space and convert with the profiles set in the Document/Target tab.

Check the maximum Total Area Coverage (TAC)

For print shops, it is important that the specifications for the data delivery and the order confirmation clearly indicate the maximum Total Area Coverage that is expected for the type of paper to be used and also the printing standard the client should prepare the printing data.

When printing on newspaper or uncoated paper and the maximum Total Area Coverage is significantly exceeded, this indicates that image data has not been optimized for the respective printing standard. Usually these are image data for coated paper in offset printing.

When optimizing PDF files via standard queues in ZePrA, the following alternatives are available in Auto Setup:

Normalize and convert Colors to the new Output Condition: Converts the data – for example from coated paper to uncoated newspaper paper – and optimizes the color appearance.

Optimize Total Area Coverage (TAC): Limits the maximum total amount of color without changing the color appearance.

Check overprinting CMY objects without any black

Checking overprinting CMY objects without any black is a rather rare special case. Regarding high color stability during production, fast drying times, and ink savings, we recommend using ColorLogic’s SaveInk queues for as many print jobs as possible.

However, if an overprinting object of a PDF file is composed of all CMY colors without any black, the resulting color impression from the overprinting object and the background may change after color optimization, due to the overprinting rules of the PDF standard. For an underlying object, the color of a channel is only completely visible if no color is present in the respective channel of the overprinting object. If an overprint object has just a slight amount of color in a channel, then only the color component of the upper (overprinting) object is visible.

If CMY parts of SaveInk profiles are unintentionally replaced by black and the overprinting behavior changes as a result, but the color is still to be saved, a new SaveInk profile must be created for which the exception Preserve 0% Black is activated. This special exception is located in the SaveInk module of the CoPrA profiling software.

Integration with Enfocus Switch

Enfocus Switch Integration

Working with Enfocus Switch

Even for highly advanced and efficiently configured applications like ZePrA, there are still application scenarios where special file treatment or an additional approval step for optimized PDF files make sense. This particularly applies to print providers and printing companies who receive PDF data from numerous customers that have been produced in a variety of different ways. The combination of ZePrA with Enfocus Switch and a preflighting solution has proven to be very successful for this kind of application.

Auto Setup

Workflow Creation Using the Automatic Setup Wizard

ZePrA has six auto setup methods to set up workflows for the most common color management tasks. It takes just a few steps to create Configurations and Queues.
To process files, either use a previously created DeviceLink profile, or use the SmartLink function to create a DeviceLink profile on-the-fly (SmartLink license required).
The Automatic Setup Wizard also allows workflows that save ink, optimize the total area coverage (TAC), and apply gradation corrections.

Step 1: Select a Setup Mode

Select Auto Setup in the sidebar. There are six different setup options for creating Configurations and Queues:

Choosing a Setup Mode

ZePrA’s Automatic Setup Wizard

  1. Normalize and Convert Colors to New Output Condition
    The content of the PDF file is first normalized to the document color space or output intent and then converted to the desired target color space using DeviceLink profiles.
  2. Normalize Color to Document Color Space or Output Intent
    The data is normalized to the document color space or output intent. After conversion, the final, normalized file consists only of a color space and spot colors, if present.
    If PDF objects are present in the RGB color space, they are converted with the embedded profile to the document color space using the rendering intent defined in the PDF file.
  3. Save inks
    The data is first normalized to the document color space and then optimized using either an existing SaveInk profile or a SmartLink SaveInk method. Three color saving methods are available.
  4. Optimize Total Area Coverage (TAC)
    The data is normalized to the document color space and the total amount of color is reduced. This can either be done using specific profiles to reduce the total area coverage (TAC), or by defining the SmartLink value under Desired TAC.
  5. Direct Color Conversion to New Output ConditionThe data is directly converted to the target color space with embedded profiles, without normalizing to the document color space beforehand. This setup mode enables the best color space utilization of the target color space and is particularly suitable for media-neutral data, e.g. RGB image data with ICC profiles.
  6. Apply Gradation Curves OnlyIf the printing process differs due to changed printing conditions (e.g. due to substrate or other printing parameters), adjustments can be done directly in ZePrA, without CtP compensation curves in the RIP, by applying gradation corrections “on-the-fly”.

Step 2: Use DeviceLink profile or SmartLink

Use an existing DeviceLink profile or use SmartLink to create and use a high-quality DeviceLink profile on-the-fly.
1. Using an Existing DeviceLink Profile
Choose a DeviceLink profile for the configuration (e.g. from our DLS DeviceLink sets, available from any ColorLogic dealer), and select it from the drop-down menu. The source and target profiles are set by the DeviceLink profile.
2. Use SmartLink
The SmartLink function creates DeviceLinks on-the-fly from source and target profiles to avoid problems normally associated with a regular ICC conversion and increases conversion quality.
Note: Requires a SmartLink license. If the SmartLink function is not available, normal ICC conversions are performed for objects with embedded ICC profiles.

Document Color Space

The document color space serves as a reference to create a uniform printing color space for the colors of the PDF file. Selecting the Prefer Output Intent checkbox will use the output intent of the PDF/X file instead of manually setting the document color space.

Rendering Intent

ZePrA contains five rendering intents in addition to the four standard ICC rendering intents. They are only available when SmartLink is licensed.

ZePrA's Standard Compression Settings

ZePrA’s Rendering Intent Options

Standard Compression: For conversions including color spaces of different sizes. Calculates a perceptive conversion for input and target profiles that is suitable for all types of gamuts.

Black Point Compensation: Use Black Point Compensation to achieve the same results with a perceptive conversion as with “Relative Colorimetric with Black Point Compensation”. When converting from a large to a small color space, the image definition is preserved in the highlights and shadows, unlike a pure Relative Colorimetric conversion. Neutral tones are converted using the relative colorimetric intent. Out-of-gamut colors are clipped.

Absolute Compression: If the color gamut is similar, but the paper shade differs significantly. In contrast to Standard Compression and Black Point Compensation, the gray balance compensates for paper coloration. The color of the original file is preserved in the best possible way on a target medium with a different paper color. Shadow areas are increased for small color gamuts. Standard Compression, the gray axis of the conversion is build relative to the paper white of the target profile.

Dynamic Compression: Compares the source color space and target color space and generates compression that minimizes out-of-gamut areas. Preserves the brightness of the original color space while reducing the saturation, therefore preserving the image definition.

Minimum Compression: Allows almost absolute colorimetric reproduction, compensating only for areas near the black and the white point.

SmartLink Methods

The SmartLink methods apply different requirements of various printing conditions so the desired color is correctly reproduced and optimally separated for a specific printing process.

Traditional Printing – Classic: Offset, gravure, or newspaper printing. Black, grey, primary, secondary and tertiary color tones of the source profile are retained. The total area coverage from the target profile is applied.

Traditional Printing – Automatic: When the color and paper of the target color space differ significantly from the output intent or document color space. The separation is retained.

Large Format Printing – Inkjet: The separation is characterized by a strong GCR and a late black start. The black point and the total area coverage are calculated automatically. Otherwise like Traditional Printing – Automatic.

Digital Printing – Toner: For toner-based digital printers and office printers. A high percentage of black is used to achieve a stable print and neutral gray balance. The total area coverage from the target profile is applied. Otherwise like Traditional Printing – Automatic.

Apply Gradation Curves Only

These gradation adjustments apply external files on-the-fly to existing curves, adjusting process colors and/or spot colors without changing the document color space.

There are two ways to correct gradations:

1: Select Curves
Select linearization DeviceLink profiles created with CoPrA or previously imported files including curves (gradations).

2: Use Curves from File
External files including the gradation corrections for the curves (gradations) to be changed can be loaded. ZePrA then imports the files into its own folder structure.

Considerations for Normalizing PDF files

When working with PDF/X-3, PDF/X-4 or PDF/X-5n files that may still contain RGB or CMYK objects with embedded profiles, normalize the files.

If the PDF file does not contain an output intent, define an ICC profile as the Document Color Space. Select the Prefer Output Intent checkbox to ensure that any existing output intent takes precedence over the specified document color space and is retained.

Step 3: Create Configurations and Queues

In the last step of the wizard, assign a Queue name. The corresponding configuration automatically receives the same name.
Define the Base Folder. The Queue and its subfolders are created. To only create a new configuration, deactivate the Create Queue checkbox.
The last step completes the workflow setup and it is immediately available.

Main Setup and Overview


Processing Jobs via Queues
In ZePrA, files are processed via queues. Each queue is assigned a configuration. A configuration contains all the necessary settings for converting and processing the file. Queues and their configurations are managed separately and configurations can be modified and re-assigned to different queues anytime.
The Jobs and Queues Overview window (Sidebar: Overview) provides an overview of the queues and associated configurations.
Queues created with the Automatic Setup Wizard usually have the same name as the corresponding configuration.
The order of the jobs to be processed is determined by their priority. Change the Priority by right-clicking on the queue and change its default setting Normal to High or Low.
Queues can be controlled with Start and Stop buttons located in the lower right corner.

Manually Create a Queue
To create a new queue, create a Base Folder, assign a configuration and a name. Use the New button in the Queues tool to manually create a queue. To configure the queue afterwards, first select the queue and then select the configuration from the Process with Configuration drop-down menu in the Options tab.

Set up a Queue Manually


All settings related to color handling and PDF processing are defined under Configurations. This includes color conversion via ICC output profiles or DeviceLink profiles, handling of mixed PDFs (documents with data in CMYK, RGB, Grayscale and spot colors) and individual settings of gradation curves and spot colors. Various presets and optimization options are available for all settings.
In the upper part of the window, select a configuration, create, rename and save new configurations.
To duplicate an existing configuration, select New, enter the new name and Save. To use a duplicated configuration, assign it to a queue.


Queues are displayed in the Overview in chronological order. The lists can be sorted by clicking on the respective column.

Processing files – Starting queues
To start a job, select Open Folder from the context menu to open the corresponding Input Folder (hot folder) of the queue. Copy or move the file (TIFF/JPEG/PSD/PSB image, PDF) into the Input Folder, or simply drag and drop the file onto the appropriate configuration in the queue overview. Alternatively, right-click on a file and copy it into the queue’s hot folder.
When a file is placed in the Input Folder, ZePrA automatically converts it according to the settings specified in the configuration and places the converted file in the Output Folder. The job ID and configuration name are added to the file name. The original file is moved to the Originals Folder. Problem files are stored in the Error Folder.

Convenient queue management

Processed Jobs
Files with a yellow warning in the overview window have been processed but may have issues. They are usually placed in the Output Folder. Alternatively, when configuring the queue, define an Output Folder with Warnings, where such files will be moved after processing. Incorrectly processed or unsupported file types are highlighted in red and moved to the Error Folder.
A right click on a job opens a context menu with the following entries:

Context menu with many useful functions

1. Click on the Extract ICC Profile icon in the sidebar.
2. Use Select to choose the file (PDF, JPEG, TIFF PSB or PSD) with the embedded profile. Click Open. Alternatively, you can drag and drop the file into the selection window.
3. The embedded ICC Profile, the PDF/X Version, and the Output Condition are displayed. The embedded profile can be saved with Extract.

Spot Color Iteration

Color deviations in printing, e.g. due to differences in printers, inks or substrates, can be minimised using the spot color iteration tool. This ensures optimum conversion of spot colors to process colors, in digital or proofing production.
Start the iteration process by printing spot color(s) converted by ZePrA on the printer to be used for the job. Test charts are measured and color deviations are optimized until the measured dE2000 values are within the desired tolerances.


Activate the checkbox Convert Spot Colors in the Spot Colors tab under Configurations. Set the Calculation Method to Precise Match or Visual Matching for the best results. Then open the Iterate Spot Colors dialog by clicking Iterate.
1. Select the Configuration.
2. Select the source spot color (PDF file or spot color library).
3. Create a test chart from a PDF file or spot color library. ZePrA uses all the spot colors it contains (solids) and converts them according to the selected configuration. Select an Instrument Setting and click Save.
4. Print the test chart without applying color management.
5. Measure the printed test chart. The reference file is automatically preselected.
6. Optional, but highly recommended: Create a spot color iteration report with Calculate Report. It contains information about the achieved and measured deltaE values.
7. Click Apply. The optimized spot colors are calculated and applied in the configuration.
Note: We recommend activating the checkbox Iterate all Spot Colors.

Spot color libraries and spot colors can be managed conveniently in ZePrA’s spot color module. Access the Spot Color Libraries in the sidebar. Libraries can be created, added, viewed and modified. Spot colors can be edited, imported or measured.
For example, spot colors from color books can be measured with a spectrophotometer or lab values can be manually entered. Color tables with spot colors can also be imported. Supported formats include: Named Color ICC profiles, Photoshop ACO color tables, Adobe ASE color tables (from InDesign or Illustrator), text files in CGATS format or CxF or CxF/X-4 files. Both Lab and spectral color values are supported. Spectral measurement data is preferable as it provides the best results.

Note: Spot color libraries are not included with ZePrA.


PantoneLIVE® from X-Rite is a cloud solution for the digital storage of spectral spot colors. This includes Pantone color books, paper-dependent “Dependent Standards”, or custom color libraries.

ZePrA includes direct access to PantoneLIVE®. A ZePrA spot color module license and an active PantoneLIVE® Production license from X-Rite are required. PantoneLIVE® libraries will be available and use them in ZePrA to process spot colors. For more information, see our online help. General information about PantoneLIVE® is available in the PantoneLIVE® documentation.


Using gradation curves allows optimal preparation of print data for output. For example, applying tone value corrections just before printing and ensuring output quality within a printing standard.

Optimal preparation of print data


In the Curve Management window, you can create New curves and Duplicate or Delete existing ones. New curves can be adjusted in the Curve Design panel by clicking and dragging the curve or by entering values. To enter percentage values in the Input and Output fields, first create an anchor point on the curve by clicking onto it. The entered values will then affect this anchor point. X deletes anchor points.

Profile Assignments

ZePrA’s SmartLink function can be customized by profile assignments. Standard Device Links, house standards or custom profiles can be assigned to configurations automatically.

To add new SmartLink profile assignments, click New at the bottom of the window under Profile Assignments 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 corresponding assignment.

CLI Module

ZePrA can be integrated into other workflows via a configurator in Enfocus Switch and generally via Command Line Interface. This enables even complex workflows including data input to sorting, preflighting, color conversion and data transfer.

Review accuracy of spot color conversion

Spot Color Report


The spot color report shows the results achieved with a spot color conversion in relation to deltaE00, deltaE76, and the separation into process colors. This allows the accuracy of spot color conversions to be checked before processing or printing, and to determine in advance how ZePrA converts spot colors (e.g. Pantone® colors) of specific PDF and image files.


  1. Configurations: Select one or more configurations from the list which contain all settings for the conversion. Only Configurations which have spot color conversion enabled are displayed in the list.
  2. Select a PDF or Image File or a Library under Source Data.
    PDF or Image File: Select the PDF or pixel image file with spot colors to be processed using the settings of the selected configuration.
    Library: Select the spot color library to be converted using the settings of the selected configuration.
  3. Select the Sort order.
    Sorts the list according to various criteria. When sorting by Delta E, spot colors with the lowest dE are listed at the top, and the highest dE at the bottom.
  4. Create the report. It can be created in various formats (PDF, XML, Text, CGATS or Color Exchange Format).
    Save: Creates the spot color report and saves it. Optionally, a Preview can be created beforehand.

The spot color report shows the results achieved with a spot color conversion in relation to deltaE00, deltaE76, and the separation into process colors.

Note: When creating the report, all spot color settings made in the Configurations are used, including manual settings and warnings. Colors with warnings are displayed in red deltaE values.

The screenshot shows the preview for processing spot colors with two different configurations. All spot colors found in the PDF file are included. One configuration uses a CMYK target profile and the other a 7C target profile. The report shows that in this case the 7C profile is much better suited for simulating the spot colors of the PDF file.
