Paper color simulation (white point correction) in v4

Introduction

If you selected the option "Paper Color Simulation" when you configured your queue (Proofing tab of the Queue Options), you can change the simulation of the paper color in ProofMaster Calibrator. This function changes the white point in the printer profile in accordance with the reference profile.

To edit the paper color simulation (white point correction)

  1. In ProofMaster Calibrator, click the DeviceLink tab.
  2. Select the queue of which you want to change the paper color simulation. A reference profile and a printer profile need to be specified for this queue.
  3. Fill in the target values ( in Lab or LCh) of the simulation of your choice. Notice the CMYK values of the inks at the bottom of the White point correction dialog box.
  4. Click Print to print two patches: one with the current values and one with the adjusted values. A job named “paper white target” is added to the queue. If the values you specified are out of the printer’s gamut, it will be indicated on the print.
     
  5. Adjust and print the values until the result is satisfactory.
    Note: Take in account that the color information of the printer profile (dfp) also matters into this process.
  6. Click Save and, if necessary, change the name of the printer profile. The printer profile you have just saved will automatically be used by the respective queue.

Example

  1. Without the “Paper color simulation” option set into the queue – render the file, in our test file the result is as follows:
  2. With the “Paper color simulation” option set into the queue –– render the file, the result is as follows:
  3. With the “Paper color simulation” option set into the queue –– go to “Calibrator->Device link->Paper color”, modify the paper color and click "Save" in order to save your paper color correction into the output profile. Render the file again, the result will be as follows:
     

Notice: 

When using a Device link in your proofing queue:

If you change the name of the profile after you modify the white point, the tuning profile will not be remembered in the queue.

So, when you change the white paper color, do not change the name of the profile (dfp) and both the tunning profile and the modified paper white will be remembered.
