Navigator DFE can import a properly generated CGAT file third-party software programs like the Ideaalliance Curve tool. 

This is useful if you prefer to use external tools for grey balancing or calibration. The imported curves are applied as a tone curve, meaning they are added to any calibration curve that may already be present. 

Important Note:
The CGAT file must contain data for the control points that the Navigator DFE expects. Specifically, there must be data for:

 0%, 2%, 4%, 6%, 8%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 85%, 90%, 95% and 100% dots in cyan, magenta, yellow and black channels.

In order to import a tone curve::

  1. Navigate to the Color Profiles tab. 
  2. Click choose file. Browse for a valid CGATs file. Select Import.
  3. Choose the calibration file from the "Additional Tone Curve" drop-down list. 
  4.  Click the checkmark icon to save your settings.
