Create an L*a*b* optimization file
You can repeat the optimization procedure as often as required and select which L*a*b* optimization file to apply. After each optimization, Color Tools displays the achieved average dE, peak dE, paper white and the percentage of colors that are within the target gamut.
- Click Print.
- Wait for the ink to dry. Then, follow the on-screen instructions to measure the chart. The first measurement forms the basis for the optimization.
This step is not necessary if you selected an embedded measuring device and used the criteria for optimization control.A green arrow pointing upwards indicates that the profile can be optimized further. A Stop sign indicates that no further optimization is possible.
Repeat the previous steps until no further optimization is possible.
It is useful to perform a visual check on the final printed chart to make sure that the color gradations have not been negatively affected by over-optimization.
- In the optimization table, click the best set of results, and then click Finish.
- Click Yes to confirm that you want to save the selected iteration as the new profile.
- Type a name for the L*a*b* optimization file, and then click Save.
Do one of the following:
Click Yes to select the L*a*b* optimization file for the workflow.
Click No to save the L*a*b* optimization file to the C:\ProgramData\EFI\EFI XF\Server\Profiles\Balance folder. You can select it later in Command WorkStation.
