Evaluation of Proof Measurement Data

Evaluate – Proof Evaluation

Evaluate can be used to check whether the proof measurement data from a media wedge fulfills the requirements for a contract proof according to ISO 12647-7 or a validation print according to ISO 12647-8. A fully-detailed report can be created with a pass/fail indicator.

Note: The Proof Evaluate tool supports all color spaces including Multicolor and spot colors. It is a powerful addition to the proofing feature introduced in ZePrA 8, as it allows you to use the reference files of the dynamic media wedges created by ZePrA for proof evaluation.

The Evaluation tab immediately shows the categories related to the chosen standard, the deltas to the reference, and a score with either a ✓ (passed) or an ✕(failed).

An overall score indicates if the proof has passed or failed.

There are two ways of selecting your reference:  

  • Choose reference data: This drop-down menu contains all data loaded under Data Sets that fit the selected proof measurement data as a reference, which means the number of patches and the color space must match. Select the reference that you want to compare with the selected media wedge measurement data. If dynamic media wedges were used in ZePrA, the corresponding reference data can be used for the proof evaluation in ColorAnt.

    Using reference data from ZePrA:
    1. Open the reference file of the ZePrA configuration in ColorAnt. It is located in ZePrA’s Report folder of the corresponding queue.
    2. Select Measure to measure the media wedge in the proof printout
    3. Open the resulting measurement file and click the Evaluate button.
    4. Select the original reference file from ZePrA under Choose reference data in the Proof Evaluation window.
     
  • Choose reference ICC profile: This drop-down menu contains all ICC profiles that fit the selected proof measurement data as reference in terms of the same color space. Choose the reference ICC profile that you want to compare with the selected media wedge measurement data.
    Note: The ICC profile is used to create virtual reference values. Depending on the accuracy of the ICC profile, the quality of the reference data can vary from very exact (e.g. CMYK profiles created by CoPrA) to less exact (e.g. small Multicolor profiles).  

Evaluation method: Select a method to either evaluate a Contract Proof according to the ISO 12647-7 standard or a Validation Print according to the ISO 12647-8 standard.

ISO 12647-7: For the evaluation of a binding contract proof use this method. 

ISO 12647-8: Checks the conformance of printing systems that produces a hard-copy validation print, directly from digital data, which is intended to simulate the expected appearance of material printed per a characterized printing condition.

Note: Recently, other visualizations of the final printed product have found a place in the printing/proofing workflow because designers and print buyers prefer not to go to the expense of using an ISO 12647-7 compliant contract proof any earlier in the process than necessary. In many situations, participants in the workflow require a hardcopy visual reference of lesser quality than a contract proof. In the past, those prints varied widely in quality and were often referred to as design proofs, concept proofs, layout prints, etc. That quality level is here being referred to as a validation print.

Report

The available input fields depend on the selected Evaluation method. Enter the required information according to the selected ISO standard.

Save Report: Choose the file location and the format for the report (PDF, HTML, XML).

The report contains all the information that you have entered, the summary from the evaluation dialog, a list of all patches with their names or IDs, the device color space, the Lab reference values, the Lab measurement value and the delta.

Video Tutorial

How to Use the Proof Evaluation Tool in ColorAnt in combination with ZePrA

Learn step-by-step how to use the Proof Evaluation tool in ColorAnt for the evaluation of a proofing media wedge created with ZePrA. In this example, we will be demonstrating the special feature of ZePrA to create a dynamic media wedge using process and spot colors and how to use the supplied reference data from ZePrA for evaluation of a Contract Proof.

Preferences

View
Choose the tool that opens at startup. Allows quick access to the preferred tool. By activating the checkbox Do not display informational popups graphical information about tools of the Sidebar will no longer be displayed. However, tool tips for features will still be shown.

Profiles
Profiles: Select the location for your profiles. By default profiles are stored in the system profile folder (except for CoPrA SP licences). To store your profiles in a different location, for example a network folder, simply activate the checkbox Custom profile folder and specify the storage path.
Subfolders for the various profile classes and color spaces are created automatically.

Note: Profiles which are not stored in the system profile folder may not be available for other programs.
For Mac users: Create a subfolder in the ColorSync profile folder to store all profiles created by CoPrA in one place. These profiles will still be accessible for all programs using ICC profiles.

 

Overwrite existing preview profiles automatically: Preview profiles can be created when creating DeviceLinks or Multicolor profiles but they can also be created in Batch Overview or Profile Manager. By activating the checkbox Overwrite existing preview profiles automatically existing preview profiles will be overwritten without warning.

Share with ZePrA

Due to the close linkage of CoPrA and ZePrA, DeviceLink profiling settings specified in CoPrA can be used by ZePrA to create profiles required for the conversion of PDF files on-the-fly.

With CoPrA 6 and higher the settings are accessible via a shared folder which has the advantage that CoPrA and ZePrA do not need to be installed on the same computer. The shared folder must simply be accessible by both ZePrA and CoPrA, either over the network, a shared local folder or the cloud.

Share CoPrA Settings with ZePrA Auto Import Folder: Enable the checkbox to share CoPrA’s settings with ZePrA and select ZePrA’s Auto Import folder.

Note: If the checkbox is enabled and the Preferences dialog closed with OK an information message will appear repeatedly asking the user if all shared presets should now be copied to the defined Auto-Import Folder.

ZePrA’s Auto Import Folder
Files (such as ICC profiles, configurations, spot color libraries, gradations or SmartLink settings) that are moved or copied into the
Auto Import folder are transferred to ZePrA’s internal dataset and can then be used by ZePrA.
When the file in the Auto Import folder is replaced by a newer version, it will be updated in ZePrA’s internal datasets as well.
Note: If a file in the Auto Import folder is deleted, it is not deleted in ZePrA’s internal dataset. For example if a SmartLink setting has been deleted in the Auto Import folder, it is still available in ZePrA’s internal dataset and if this setting is deleted in ZePrA’s dataset, it is still available in the Auto Import folder.

Report Creation
Default save path: Defines the location for the Profile Report.

Default report format: Specify whether to create a PDF report with sample images or an XML report with pure data.

Default DeltaE Method: Determines the DeltaE method to calculate color differences for profile reports (dE76 or dE2000).

Open profile reports automatically with default viewer: If enabled, the profile report will be opened and displayed by the default PDF or XML viewer immediately after its creation.

Report Customization
Here you can enter a subtitle or add your own company Logo to the profile report. By default CoPrA’s icon is used.

Protected Mode
The Protected Mode allows to lock and protect all custom settings. If activated – with or without a password – changing a selected profiling setting is denied. This feature proves to be practical if multiple operators in an organization are creating profiles and only a defined set of settings should be used instead of every operator using his own settings. Once the protected mode is activated, options in the Preferences are disabled and importing and exporting of settings is denied.

If you need stricter permissions, the Protected Mode can be used with a password.

Set Password: Enter a secure password and confirm by entering it a second time. If a password has been set, it must be entered each time the protected mode is to be deactivated. To remove or change the password, click Reset Password.

Note: Remember your password well or keep it in a safe place!

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.


Activating a License

Load the license file in the tab License details under Registration to activate the application.

After installing the permanent license file, the licensed modules are displayed under License details.


Using One License File on Multi-User Systems

macOS

Copy the license files of ColorLogic applications into the following folder:

/Users/Shared/ColorLogic/LicenseInstall.

  • Create the folder if it does not exist.
  • Check the folder permissions.
  • When the application is launched, it will check the specified folder by default.

Windows

Copy the license files of ColorLogic applications into the following folder: C:\Users\Public\Documents\ColorLogic\LicenseInstall.

  • Create the folder if it does not exist.
  • Check the folder permission.
  • When the application is launched, it will check the specified folder by default.

Complete instructions on how to download and install ColorLogic applications and how to request and activate a demo license can be found here.

Demo Licenses


ColorLogic offers 14-day trial licenses for the applications CoPrA, ZePrA and ColorAnt allowing the user to evaluate the software features and performance.


Restrictions with Demo Licenses

All profiles created with a demo license in CoPrA can only be used correctly in ColorLogic applications.

A ZePrA demo license gives users a 14-day evaluation period to try all the functions of ZePrA within the application. All files converted with a demo license in ZePrA are watermark protected. If it becomes necessary to test ZePrA within a workflow without the watermark during the test period, contact your dealer for instructions.


Requesting a Demo License

  1. Click on Registration in the lower left corner of the sidebar.
  2. Click on the tab Demo license request.
  3. Enter all required information.
  4. After selecting the country, the software shows a list of available dealers in that region. Select a dealer and click on Send direct request. The relevant demo license will be send to the specified email address within a few minutes.
  5. Save the license file (*.lic) contained in the email on the computer being used.
  6. Load the license file in the tab License details under Registration to activate the respective application.

The expiration date of demo licenses is shown under License details right after activation.

FAQ


Does the license file have to be saved on the USB dongle for USB dongle-based licenses?
No, the license file does not have to be saved on the USB dongle. However, it is recommended if the application is to be used on several computers, as the required license file is then always available.

Why does my software not work anymore?
Please make sure that the USB dongle is plugged in and that the serial number of the license file matches the serial number under Registration.

What is the correct order to start the application with USB dongle based licenses?
First plug the USB dongle into your computer, then start the software and load the license under Registration.

What if the application with a computer-based license is to be used on another computer (e.g. if the old computer is broken)?
In this case, please contact the dealer from whom you purchased the software. He will provide you with a document (License Transfer Agreement) for you to sign, in which you agree to delete the old license file and not to use the software on the old computer anymore. You will then receive a new license file for the new computer.

Important: If a computer-based license is to be used, the application must be installed on exactly the computer on which you want to work permanently. You should also make sure that no USB sticks etc. are present before you start the software and open the Registration dialog.

Tip: If you send the serial number to the dealer, it is best to copy and paste the serial number from the Registration dialog (this is easier than writing it down or sending a screenshot). The permanent license file runs only and exclusively on this computer. If you have a computer-based license, you cannot use the software on another computer.
