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.
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.
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).

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. No gamut will be displayed for CMYK and Multicolor DeviceLinks. For DeviceLinks with source and target with less than 4 channels (e.g. RGB-2-RGB, Gray-2-RGB, 3CLR-2-3CLR) a gamut with DCS coordinates will be displayed.
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.
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.
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 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 name in the Search for function set to Notes and all profiles with its name will be listed.
