CoPrA | Profile Manager EN
Using Profile Manager
Profile Manager allows viewing, organizing, analyzing, comparing or even adapting profiles without leaving the CoPrA environment. The main window shows all profiles stored on the system. The unique ability of Profile Manager to display and handle all types of profiles, including DeviceLink and Multicolor profiles, makes it the ultimate tool for everyday color management.
Profile Manager includes six different tabs (General, Curves, Gamut, Colorants, Workflow, Notes) which provide access to all important functions. Apart from that, it allows to quickly and comprehensively verify the quality of profiles by means of a Profile Report.
Profile Manager Features
Main window features
Profile Filter: Offers various filters for searching profiles and a profile list showing all available profiles on your system.
Filters for Searching Profiles
Using the four drop-down menus and the text input box narrows down the search to find profiles more quickly.
Device Class: Displays all profiles of a specific device class. You can exclusively display Input (scnr), Output (prtr), Monitor (mntr), DeviceLink (link), Color Space (spac), Abstract (abst) or Named (nmcl) profiles.
DCS and PCS: With DCS (Device Color Space) and PCS (Profile Connection Space) all profiles of a specific color space can be viewed.
Profile Type: Limits the search to profile types. Returns fast search results, especially in combination with Search for file name.
Search for: Enter a search term to search specifically for a particular text in the profile name. For example, by entering ‘preview’ all preview profiles are shown. Searching for Name, Manufacturer, Creator, Date, Notes, System Profiles, SaveInk Profiles, Updated Profiles or Correction DeviceLinks is also possible.
Note: Narrowing down the search to a specific date can be useful to display all profiles that have been created on a given day.
Invert: All filters and keywords can be inverted by clicking on the corresponding checkbox. For example, by selecting DeviceLink under Device Class, all DeviceLink profiles will be shown. By activating the checkbox Invert, all profiles except DeviceLink profiles will be shown.
A click on X resets all filters and displays all profiles.
The list of available profiles is updated automatically every time Profile Manager is accessed (at program start or whenever it is brought to the foreground).
A right-click on a profile opens a context menu. The following options are available (depending on the profile type and the licensed modules):
The entries Create Profile Report (PDF)/(XML), Save Preview Profile, Calculate Gray Profile and Smooth Profile LUTs are only available if a valid license for the corresponding modules exists.
The context menu also allows you to create ACV or XML curves from a selected Linearization DeviceLink profiles.
Extract source and target ICC printer profiles of DeviceLinks
Embedded source and target ICC printer profiles of DeviceLinks can be extracted using the Install embedded profiles option (only available when embedded profiles are present). This is useful if you have been sent a DeviceLink profile and the required printer profiles are not available on your system.
Open the context menu by right-clicking on the respective DeviceLink profile and click on Install embedded profiles. The extracted profiles are stored in your profile library. A message at the bottom of the window confirms the action and the location.
The four buttons below the profile list differ for macOS and Windows (see screenshots).
Delete: Deletes the selected profile.
Set as reference: The selected profile acts used as reference profile for a gamut comparison with another profile. It is displayed at the right bottom of the window under Reference profile and can be activated or deactivated by its checkbox. After activation it is available for a Gamut Comparison (see below) and will be shown in the 3D and 2D view of the gamut together with the selected profile. To view only the selected profile, hide the reference profile by unticking the checkbox.
Save: Saves any changes to a given profile.
Open: Opens the ICC profile using the default system program. macOS opens the ColorSync Utility which displays individual tags and tables of the selected profile.
Show file: Opens the folder in which the selected profile is stored.
Description: Displays the name of the profile which can be changed and saved by clicking on Save.
Copyright: Displays the non-editable copyright of the profile.
Header: Shows all important entries in the profile header.
A Gamut Comparison can be created by clicking on the double arrow icon at the bottom right of the window (see screenshots). In this process the gamut size of the selected profile is calculated and compared to the gamut size of the selected Reference profile (see above). The selected profile is displayed under Profile path.
The gamut Lab Volumes can be calculated without a Reference profile allowing for a quick check of the gamut size for selected profiles (Sample).
Shows the curves for the selected profile. For each Device Class only the appropriate options are available in the drop-down menu, e.g. for DeviceLinks, device profiles or monitor profiles (see screenshots).
For example, the purity of the channels can be displayed for DeviceLinks. For printer profiles you can view the curves for the gray balance, but many more curves and color space views are available additionally. Specific curves are available in the drop-down menu for monitor profiles. Try out the various options and curves to get an overview of the characteristics of your profiles.
A special feature of Profile Manager is the possibility to view the gray balance of a printer profile for different rendering intents in the profile. Thus the gray balance can be viewed using the relative colorimetric rendering intent with black point compensation (see screenshot).
Gray balance of a CMYK printer profile when using the relative colorimetric rendering intents with black point compensation.
The tab Gamut displays either a 2D or a 3D representation of the color space for the selected profile (see screenshots).
For CMYK printer profiles, the maximum gamut is displayed (disregarding separation limitations). The gamut display for Multicolor printer profiles is limited.
The gamut of DeviceLink profiles is displayed regardless of the color spaces of the source and target profiles (e.g., RGB-2-RGB, CMYK-2-xCLR, RGB-2-xCLR) but can only be displayed if the source and target profiles are found on the system.
The preview reflects all DeviceLink settings (Rendering Intent settings, Exceptions settings, …) in 2D and in 3D.
In 2D, the lightness slider can be used to view the gamut border of a lightness slice of the selected profile. Use the ab-Projection checkbox to see the entire gamut as a flat projection on the ab plane.
The representation changes according to the selected Rendering intent.
The 3D view features a rotatable gamut. Use the Zoom slider to magnify it.
Gamut Zoom: Increase or decrease the Gamut view by pressing cmd (macOS) or ctrl (Windows) and the left mouse button while moving the mouse forward (to zoom out) or backward (to zoom in).
Note: The default 3D gamut viewing method of CoPrA 9 and higher is based on a 1:1:1 axis ratio. This means that the axis ratio of L to a+ (a-) as well as to b+ (b-) is identical. Up to CoPrA 8, the L axis was twice as long in ratio (see screenshots).
To use the 2:1:1 axis ratio view used in CoPrA 8 or older, change the 3D Gamut Axes Ratio (L:a:b) setting under Profile Manager options in the Preferences.
Please note that the 3D gamut view options also affect the gamut view in the Printer Profiling tool on the Color Generation tab.
Sample Data: Sample data can either be image files (TIFF, JPEG or PSD files) or measurement data as text files (CGATS files in text or XML format, CxF files or ACO files) or a single Lab value entered manually. Based on the position of the values in the Lab color space the 3D or 2D representation quickly reveals whether images or color values can be reproduced within the desired printer gamut using the set Rendering intent. Select 3D and move the mouse pointer over the color patches to highlight them and to display their name, Lab value and their deltaE (in dE76) to the gamut border of the profile.
Note: The deltaE is only appropriate for the Absolute Colorimetric Rendering Intent and will not be shown for other rendering intents.
Note: Image files (JPEG, TIFF or PSD) will be split into color patches using a lower resolution and will then be converted directly to Lab using either the embedded profile or the default profile and the set Rendering intent. The image will be converted and displayed as dots. The selected profile is shown in brackets behind the file name. If no profile is embedded AdobeRGB is used for RGB images. CMYK images without a profile are assumed to be in the CMYK color space of the selected profile. The used color space is always shown in brackets behind the file name.
A context menu with more view options can be opened with a right-click on the gamut view. From there you can switch the Grid, Axes and Axes Labels on and off. When analyzing Sample Data, the sphere size can be increased or decreased. For a better representation of the Sample Data, the gamut view can be switched between a Gamut Surface view and a polygonal gamut grid view.
The gamut of the selected profile can be compared to the gamut of another profile. Use the Reference profile checkbox to select the profile you would like to compare. In the 3D view, the reference profile is displayed in a semi-transparent white color, in the 2D view it is displayed with a red outline.
The gamut Lab Volumes can be calculated in the Gamut Comparison even without a Reference profile, allowing for a quick check of the gamut size for selected profiles (Sample).
The Colorants tab shows the Colorant Table of the profile (if available, for example, for Multicolor profiles and Multicolor DeviceLinks). Both the Name and the Lab Values can be edited and saved. A small color patch at the end of each line shows the current Lab value in true colors. In addition, creating a colorant table or loading an existing table is possible.
Note: If Multicolor profiles do not list these tables correctly, it is an error in these profiles which can be corrected by using the function Create Table.
Note: Printer profiles only have one colorant table, DeviceLinks, however, may have up to two colorant tables (for Multicolor-to-Multicolor-DeviceLinks).
In the tab Workflow the Source and Target Profile of a DeviceLink and the PDF/X Information can automatically be entered in the profile which allows the automatic creation of configurations in ColorLogic’s color server ZePrA. This requires the source and the target profile of the DeviceLink. ZePrA then automatically reads out the information about source and target profiles as well as the PDF/X information from the loaded DeviceLink and applies them in the configuration (PDF/X information can be entered for CMYK and Multicolor printer profiles or DeviceLinks).
The tab Workflow allows the user to add this information to self-created profiles. Profiles of other manufacturers can also be optimized for ZePrA’s workflow.
The Notes tab allows to leave custom notes linked to the selected profile. These notes can easily be found later using the Search for function under Profile Filter. Simply select Notes in the drop-down menu and enter the search text in the box below.
Example: Leave the name of a customer as a note in the profiles you have created for that customer. If you search for these profiles later, simply enter the customer’s name in the Search for function set to Notes and all profiles with its name will be listed.
CoPrA | Image Conversion
The Image Conversion tool applies the complete user-defined color management workflow to the selected image and allows comparing its effects against the original source image.
A preview of the selected image is shown in the preview pane on the right. Using the comparison area of the image preview you can compare the source image file with the conversion to the target profile using the source profile and the selected rendering intent. The comparison area can be resized using an adjustable overlay tool. This way, the effects of the defined color management workflow can easily be compared to the original source image.
The image preview uses either the embedded profile of the loaded image or – if there is no embedded profile – the specified Source Profile to convert the image colors to the Target Profile via the selected rendering intent. Since the complete color management workflow is applied to the display profile, the image is shown in true colors (provided the monitor is properly calibrated).
Conversions can be saved in piled layers in a single file to better check different color conversions in Photoshop.
Load an image file (TIFF, JPEG, PSD) to convert
Either drag-and-drop the file to be converted onto the Source File button or click the button and select the file.
A preview of the image is displayed in the preview pane on the right. The comparison area of the preview pane shows the image after the conversion to the target profile using the source profile and the selected rendering intent. It can be resized using the adjustable overlay tool. This is done by moving the lines up/down or left/right while holding down the left mouse button.
Note: The Image Conversion tool does not support retaining Photoshop layers or transparencies. Nonetheless image files such as Photoshop PSD and TIFF files with layers or transparencies will be converted correctly, however, only the compatibility layer will be color converted while additional layers and transparencies are removed.
Choose a source and target profile or a DeviceLink profile
Apply either a normal ICC conversion with source and target profile or a DeviceLink conversion.
For a standard ICC conversion from source to target profile, the Rendering Intent can be defined. In addition to the typical four ICC rendering intents, Blackpoint Compensation is available as a fifth option.
- Blackpoint Compensation is the relative colorimetric intent with additional black point compensation, as in Adobe Photoshop.
- All profile drop-down menus function like search fields. Simply type in some letters of the desired profile and only those profiles containing these letters will be shown in the list. To select a profile simply click on it.
Alternatively you may open the drop-down menu with the little arrow on the right and select a profile from the full list as usual.
For a DeviceLink conversion select the desired DeviceLink profile from the drop-down menu Source Profile. In this case it is not necessary to select other settings, such as the Target Profile or a rendering intent, therefore, these settings are grayed out.
Note: Image Conversion supports serialized profiles as well as encrypted demo profiles. Serialized profiles are those created with CoPrA SP (Serialized Profiles). Profile quality can be evaluated from either serialized or encrypted demo profiles when converting images.
If a serialized profile is to be embedded in the converted image file using Embed target profile, CoPrA will decode and embed the profile in the converted image with a smaller grid size. This ensures that other applications display the converted file correctly. Note, however, that this profile cannot be used for production purposes as the profile quality is reduced. For that reason, such profiles are marked as LOW QUALITY VERSION FOR DEMO ONLY in the file name.
Convert to Lab: Converts the image into the Lab color space which is useful for comparing images with differing target color spaces or to evaluate the color appearance of Multicolor profiles. The latter is very convenient as Adobe Photoshop does not display Multicolor images correctly in the preview and does not support conversions from Multicolor to Lab.
Paper White Simulation: This option can be used as a soft-proof in the preview for the defined color management workflow. If activated, the complete profile settings and rendering intents will be simulated on the screen under Target, including the paper white simulation.
In addition, when the Convert to Lab checkbox is enabled, the Paper White Simulation checkbox can also be activated. If activated, the conversion to Lab uses the absolute colorimetric rendering intent, if disabled, it uses the relative colorimetric rendering intent.
Embed target profile: If a target profile is available it can be embedded in the converted file. This is also true for target profiles of DeviceLinks.
Black Ink Simulation: This option can be used as a soft-proof in the preview for the defined color management workflow. The complete profile settings and rendering intents are simulated on the screen under Target, simulating the Black Ink (relative colorimetric rendering intent).
Note: When both the Convert to Lab and the Black Ink Simulation checkboxes are enabled, the relative colorimetric rendering intent is used when converting to Lab.
If both simulations (Paper White Simulation and Black Ink Simulation) are disabled, the rendering intent Relative Colorimetric with Black Point Compensation is used.
Select a Mode
Save Image: Saves the converted image. Available file formats are TIFF, JPEG or PSD.
Note: Only suitable file formats are listed, since some formats do not support all color spaces.
Use Layer: Allows adding layers to a converted image in PSD file format. Other formats can not be selected.
For layers converted with a SaveInk DeviceLink profile, the InkSave value is shown.
This allows the creation of a multi-layer file using different SaveInk profiles and an ink saving/quality comparison in Photoshop.
The saving of each profile is also immediately shown as information at the bottom of the Image Conversion tool.
Note: The InkSave value is displayed for CMYK-to-CMYK conversions and CMYK SaveInk DeviceLink profiles only. CMYK-to-CMYK conversions may result in higher ink consumption and therefore negative InkSave values.
Add Layer: To test various profiles, the same original image can be converted again with different profiles, and the resulting files can be stacked as layers in a single file. Such a PSD file allows users to switch between the layers in Photoshop to evaluate the quality of the conversions. For a better identification of the profiles that have been used the layer names contain the profile names and the rendering intents.
Select Layer File: Defines the image file to which the new layer will be added. Either accept the suggested file name or enter a custom file name.
CoPrA | Batch Overview
While a profile is calculated, the next measurement data can be loaded, the profiling settings can be customized or different settings of a profile can be prepared. All profiles that are calculated appear in the window Batch Overview and are processed in order. Users can continue working while CoPrA processes the list.
Profiles will appear automatically in Batch Overview when profile creation begins, for example when recalculating DeviceLink profiles.
Three buttons on the upper left of the window start or stop the calculation of profiles or remove profiles from this view.
The upper right tool set:
- PDF and XML: Create PDF or XML reports (XML reports require CoPrA L or higher)
- Open Report: Opens existing reports
- Create preview profile: Subsequently creates preview profiles
- Show in Profile Manager: The selected profile is opened directly in Profile Manager
- Show in file manager: Opens the location of the profile
The actions can also be accessed by right-clicking on a profile for a contextual menu.
The column Status displays the progress of the profile processing.
