Activation

Installing a Permanent License

A permanent license will be provided by your dealer after purchasing the application. Permanent licenses are available as computer-based or dongle licenses.

Computer-based licenses are always tied to the computer on which the software (CoPrA, ZePrA or ColorAnt) is installed. This is useful for temporary test purposes. Computer-based licenses are also required if the computer lacks an USB port or space for an USB dongle, i.e. a rack server.

USB dongle licenses are serialized to the dongle. The USB dongle communicates with the appropriate software license and enables the software to be used on different computers. To assign the license to the USB dongle, it must be connected to the computer before starting the software.

After purchasing the software, a permanent license file (*.lic) will be sent via email.

CoPrA 6 Packages and Add-on Modules

03 PRINTER PROFILING

New Printer Profile

Depending on the CoPrA package, different profiling functions are available. It’s possible to test all functions with a demo license. With the appropriate modules create profiles for the color spaces Gray, RGB, CMY, CMYK or Multicolor.

A test chart with various color patches of the corresponding color space is required as a basis for each printer profile. There are two ways to obtain measurement data for creating a printer-specific ICC profile:

  1. Measure and optimize a test chart with an appropriate software (e.g., ColorAnt) and load the measured values into CoPrA
  2. Create the measured values directly in CoPrA using the integrated Measure Tool

ColorAnt has the advantage that measurement errors, printing errors or other artifacts (e.g., inhomogeneities) can be eliminated. By analyzing and optimizing the measurement data, the profile quality is increased, which in turn, leads to improved production reliability.

Note: For most CMYK printing processes we recommend the test chart IT8.7/4. For RGB printers we recommend test charts with patches (900 and more). For Multicolor printing processes, either use the test charts and reference files supplied with CoPrA, or create them with ColorAnt.

To create printer profiles, simply load the measurement data and reference data and select a setting for profile calculation.

Printer Profiling start screen

CoPrA includes a large number of standard settings for common printing processes (e.g., digital printing). Under Customize, further settings can be configured, e.g., settings for Color Generation or for determining the first printed tone.

The various options for defining the black point and the gray axis allow precise control of the separation properties.

Procedure

  1. Load the measurement data (alternatively via drag and drop).
  2. Select a setting for the used printing process.
  3. Optionally: Click Customize to set Perceptual Rendering, Measurement Processing, and Highlights settings. Detailed information can be found in our online help, which can be accessed via the ?.
  4. Click Next and specify a Name for the new profile. CoPrA automatically suggests a profile name based on the measurement data and settings. Select the ICC profile Format (V2 or V4) and the profile Size (defines the number of points in the profile). Optionally, a profile report can be generated automatically. This report contains detailed information about the profile, the color range, the gray balance, saturation, linearity and also conversions of sample data.
  5. Create the new profile by clicking Save. The progress can then be followed either in the footer or in the Batch Overview.

Creating a profile: Format, Size and Further Processing

Update Profile

CoPrA has an innovative method to update ICC output profiles without printing extensive test charts and defining profile settings. With a small test chart or control strip, an existing printer profile can easily be adapted to changed printing conditions.

Updating printer profiles – small control strips are sufficient

Procedure

  1. Print a small Reprofiler test chart (or control strip) on the printer to be updated and measure it (e.g., with ColorAnt). The test chart can also be measured directly in CoPrA by opening the Measure Tool with Measure.
  2. Load the measurement data, alternatively by drag and drop. 
  3. Click Next. CoPrA automatically searches for the profile that best matches your measurement data and displays it in the drop-down menu.
  4. Select the profile to be updated from the drop-down menu. For more information, see our online help.
  5. Click Next, name the updated profile and select Size and Format.

Settings for updating printer profiles

Directly create a profile report (optional), a profile comparison report (to see the differences between the original and updated profile) or a correction DeviceLink.

04 DEVICELINK PROFILING

DeviceLink

DeviceLink profiles have some advantages over standard device profiles:

  1. DeviceLink profiles perform a direct conversion between input and output color spaces. Color values or color combinations can be protected or individually customized and will only be altered where necessary.
  2. DeviceLink profiles compensate many weak points of conversions using ICC output profiles. For example, the DeviceLink allows preservation of the black channel so that text is printed with black ink rather than using four inks.
  3. Ink can be saved (SaveInk) and the result can be adapted to the paper white.
  4. Proofing: Iterated DeviceLinks also provide a substantially increased proof quality.

CoPrA allows DeviceLink profiles to be created for all combinations of color spaces: Gray, RGB, CMYK and Multicolor. 

ICC printer profiles are required to create DeviceLink profiles. You can easily create these in CoPrA (using the New Printer Profile tool).

Procedure

  1. Define the Source Profile and the Target Profile.
  2. Select a Setting for the printing method used. The names of the settings are based on typical printing tasks.
    Optionally: Click Customize to modify the selected setting. Detailed information can be found in the online help, which can be accessed via the ?
  3. Click Next.
  4. Name the profile and select the Size and Format of the ICC profile.
    You can also (optional) create a profile report or a preview profile.
  5. Create the new profile by clicking on Save. The progress can then be followed either in the footer or in the Batch Overview.
Editing

Allows customized DeviceLink profiles to be created from individually modified test charts (EditTargets). This opens up a multitude of possibilities, e.g., for recurring retouching work on similar image data, or to automatically include color corrections in profile data.

These profiles can then be used automatically on color servers such as ColorLogic ZePrA.

Open one of the supplied EditTargets (for CMYK, RGB or Grayscale) in an image editing program (such as Adobe Photoshop) and make any desired color corrections. Add other images to the chart to customize it. The patch in the upper left corner cannot be covered, as CoPrA will read the patch to create the DeviceLink.

Open the corrected EditTarget in the Editing tool, either via drag and drop or via the Select Edited Testchart button. If a profile is included in the loaded EditTarget, it is automatically selected as the Target Profile. The Source Profile must then be specified manually. If no profile is included, source and target profiles can be assigned manually.

Data of an edited test chart (EditTarget)

The assignment of profiles also has the advantage that the color patches are displayed in with an accurate preview in CoPrA. Another advantage of an edited DeviceLink with assigned source and target profiles is that this profile information is stored in the PSID tag of the profile and an intelligent workflow solution, e.g., ZePrA, can automatically create configurations from it.

Evaluate the edits for each color patch. The original unedited EditTarget serves as a reference. For each color patch the original color value is located in the upper left half of the diagonally divided color patch, and the edited color value in the lower right half. Move the mouse pointer over the chart and the color patches are displayed together with further color information and a difference display in brackets (color space and TAC value). The adapted DeviceLink profile can then be created.

Procedure

  1. Open one of the supplied EditTargets (in the menu Tools > Open EditTargets folder).
  2. Modify the EditTarget in an image editing program until it meets requirements and then save it.
    Note: Never change the size and position of the control elements (patches) in the upper left corner. Do not save the image as a JPEG file.
  3. Open the customized EditTarget in the CoPrA Editing tool and activate additional options if necessary, e.g., for keeping colors pure. More information can be found in the online help.
  4. Name the profile and select the Size and Format of the ICC profile.
    Create a profile report or embed profiles (optional).
  5. Create the new profile by clicking on Save. The progress can then be followed either in the footer or in the Batch Overview.
SaveInk

SaveInk profiles use fewer combinations of Cyan, Magenta and Yellow and more Black ink. The modified black structure allows you to save ink – without sacrificing quality and at the same time control the overall ink application. CoPrA 6 adds the ability to apply ink saving to Multicolor profiles. 

A moderate SaveInk setting primarily stabilizes the printing process.

With a stronger setting, it’s possible to further reduce the amount of colorants. The SaveInk function can also be combined with other functions in CoPrA, such as SaveInk with a color space change or SaveInk for Multicolor profiles.

Settings for creating SaveInk profiles

Procedure

  1. Load the CMYK Printer Profile from the drop-down menu.
  2. Select a Setting for the desired ink saving.
    Optionally: Click on Customize to modify the selected Setting. Detailed information on this can be found in the online help, accessible via ?.
  3. Click Next.
  4. Name the profile and select the Size and Format of the ICC profile.
    You can also (optional) create a profile report or embed profiles.
  5. Create the new profile by clicking on Save. The progress can be followed either in the footer or in the Batch Overview.
Iterate

An existing DeviceLink profile can be optimized based on measured color values by using a custom test chart (can be created with ColorAnt/Custom Chart). The iteration calculates a new DeviceLink profile based on the original DeviceLink profile and the measured values, containing the same settings as the original DeviceLink. The new profile can be reinserted for iteration until the desired result is achieved.

Procedure

  1. Select Iterate in the sidebar.
  2. Select the DeviceLink you would like to iterate from the drop-down menu. Make sure that both the source and target profiles used in the DeviceLink are available in the ICC profile folder of your operating system.
  3. Convert the test chart to be used for iteration with the DeviceLink profile and print it on the printer using the same settings as for the profiling test chart for this printer. The test chart can be converted using CoPrA’s Image Conversion tool.
  4. Measure the printed test chart in ColorAnt, save the measurement data and open it in CoPrA’s Iterate tool.
  5. Click Save to calculate the new DeviceLink profile and save it in the ICC profile folder.

Note: The newly created DeviceLink will have a more accurate color rendering for most in-gamut colors compared to the original DeviceLink profile.

Linearization

DeviceLink Linearization optimizes the tone values of primary gradation ramps for any printer and color combination. The goal of linearization is to produce adequate differences from white to 100% of primary inks, smooth gradation curves and adjust primary colors to a defined, reproducible condition.

Procedure

  1. Print primary ramps on an uncalibrated output device with no color management.
  2. Measure the test chart and optimize the measurement data with and appropriate software (e.g., ColorAnt) and load the measured values into CoPrA; or create the measured values directly in CoPrA using the integrated  Measure Tool.
  3. Click Customize and choose one of the default Settings and Calculation Methods
  4. Click Next and set the profile settings. Generate a Profile Report to get details on the profile.
Recalculate

The Recalculate tool can be used to recalculate current DeviceLink profiles with a new source or target profile. This is particularly useful if the Update Profile tool was used to create an optimized printer profile from a reference profile and then all DeviceLink links that contain the reference profile are to be recalculated with the optimized profile.

Procedure

  1. Load a CMYK printer profile from the Current profile drop-down menu.
  2. Select the ICC profile to replace the current profile from the Recalculate with menu.
  3. Under Saving Options you define whether you want to Create new profiles (DeviceLink profiles) or Overwrite existing profiles.
  4. Define the names of the newly calculated DeviceLinks and, if necessary, the backup copies in the Template text field.
  5. Use the checkboxes to select the DeviceLinks to be recalculated. With the settings All, None and Invert you can activate or deactivate checkboxes all at once.
  6. Start activates the recalculation of the DeviceLinks. The progress can be followed in the Batch Overview.

05 TOOLS

Image Conversion

The Image Conversion converts pixel-based files for profile evaluations, e.g., to find the profile settings that produce the best color reproduction, or when evaluating a demo version of CoPrA. It is also useful for testing the profile quality within CoPrA on images, since typical applications often do not support all types of DeviceLinks (e.g., RGB to CMYK) or Multicolor profiles. 

When testing a demo version of CoPrA, file conversion allows images to be converted with CoPrA demo profiles (encrypted profiles) for further evaluation in other programs (e.g., Photoshop). File formats supported are PSD, TIFF and JPEG files that can be converted using ICC device profiles or DeviceLink profiles. 

Converting pixel-based files for profile evaluations

 

Profile Manager

The Profile Manager allows to manage, organize, analyze, compare and customize profiles without leaving the CoPrA working environment. The main window displays the profiles available on the computer. The Profile Manager can handle all profile types, including DeviceLink and Multicolor profiles.

The six tabs (General, Curves, Gamut, Colorants, Workflow, Notes) gives access to all essential functions. Quickly and comprehensively check the quality of your profiles by creating a profile report (right click).

Managing profiles with the Profile Manager

Batch Overview

Batch processing allows profiles to be calculated and other profiles to be prepared in parallel.

Advantages of batch profiling: 

While a profile is being calculated the next measurement data can be loaded, profile settings can be defined, or different variants of a profile can be created. All profiles that are processed appear in the Batch Overview window and are processed one after another. Thus you do not have to wait with your next steps until the previous profile has been calculated.

Profiles automatically appear in the Batch Overview when the creation of one or more profiles is started, for example, when recalculating DeviceLink profiles.

In the upper left area of the Batch Overview window there are three buttons allowing to start and stop the calculation of profiles or to remove profiles from the view.

The Batch Overview shows the status of the profile calculation
