   2. Perform one of the following actions:
      • If you already have a P2P25, P2P51, or other measurement data file for your print device, you can import it.
      • Measure a built-in P2P or P2P51 chart. You can also use a Full Color chart.
5. Define the G7 calibration:

   3. Click the Process Inks tab and select G7.
   4. Optionally Click View Curves... to check the shape of the calibration curves. If the curve correction appears too aggressive in the 3/4-tone and shadow region, adjust the 3/4-tone Correction slider. This may occur if the 100% CMY patch has a strong cast.

Note: If the calibrated output device condition has extended process inks, they are calibrated to linear Spot Color Tone Value (SCTV) response. The curve method is renamed Gray Balance and Spot Color Tone Value.
