Softproofing PDF image files

Softproofing in ZePrA offers a true color presentation of jobs on the monitor, with overprinting elements and transparency effects also displayed correctly.

Creating a softproof:

  1. Go to the Navigation Panel and open Overview/Jobs and Queues Overview.
  2. Right-click on a job in Pending Jobs or Processed Jobs to open the context menu.
  3. Select the option Screen Preview. The file is displayed in a window.

Activate the Softproof Color Management Settings via the colored icon in the title bar of the window.

Simulation Profile: The colors will be rendered through the selected Simulation Profile to the monitor profile. As a default, the output intent that ZePrA has embedded in the processed file will be used and shown in brackets. The setting is similar to the Output Preview in Adobe Acrobat

Note: The Default Profiles on top of the dialog and the Prefer embedded Profiles checkbox are only relevant in the case that the simulation profile differs from the color spaces in the file itself.

Rendering Intent: A color conversion method (rendering intent) must be selected for calculation. Typically, only rendering intent directly from the Simulation Profile chooser needs to be selected. The rendering intents include not only the normal ICC intents and relative + Black Compensation, but also include three special ColorLogic intents:

Relative+ and Absolute+: have an impact if the black point information contained in a relative matrix monitor profile indicates that the black point is lighter than L* = 0. The softproof becomes a little darker as a result of this, which usually leads to a visually better match with a reference proof.

Relative Lightness: Based on the absolute colorimetric intent with paper color simulation. The lightness of the paper color simulation is scaled to the maximum displayable lightness of the monitor, the color of the paper color simulation and the gray balance of the softproof as a whole being preserved. This setting makes sense if the absolute colorimetric softproof is visually too dark, as is often the case in newspaper printing for example.

If there is no Simulation Profile available in the file (no profile shown in the brackets), select the desired profile from the drop down list. For rendering intent, we recommend relative or absolute colorimetric or ColorLogic rendering intents.

For monitor presentation, the monitor profile stored in system is automatically selected.

Click Apply to visually display the settings and Save to save the window with the settings and then close it. Next time the window is opened the settings will be retained.

Note: In order to select the correct softproof intent, it is generally advisable to use not only the monitor, but also a dimmable standardized light box with a reference proof for visual comparison.
