Spot Pro optimizes one or more selected spot colors for a given media or substrate and an output profile. Optimization may reduce the color difference (∆E) and provide a better colorimetric match.

1. In Spot Pro, select one or more spot colors.
2. Click Optimize.
3. Select the measurement instrument from the list.
   Note:

   Only supported inline measurement instruments are shown.

4. Click Next to the Job Properties window.
5. Set the media or substrate source.
   Note: Do not change the color settings.
6. Click Print to print a chart of the spot colors to be optimized.
7. Follow the on-screen instructions to measure the chart.
8. Click Next.

   Spot Pro displays the achieved average ∆E and the maximum ∆E.

9. Click Iterate to repeat the optimization procedure until no further optimization is possible.

   In the optimization table, the last iteration result is shown, and click Finish to save your optimization.

   You can select a particular iteration and delete it from the optimization table.
