Spot Color Optimization
// WEB«
Using the SPOT COLOR CORRECTION tab you can optimize the spot color
correction file (*.SCG). This will not adversely affect process colors, as
they are corrected by a separate color table.
1. Click the EDIT button.

2. Click CORRECTION WIZARD and follow the instructions on the screen.
3. Select, configure and test your measurement device.
4. Select the spot colors to be optimized.
We recommend not to select any out-of-gamut colors. You should
optimize them manually after completing this wizard.
5. A test chart is created and printed automatically using the settings of
the selected queue. The current spot color correction file is applied.
6. Measure the test chart. The spot color correction file is optimized
automatically, i.e. the CMYK values are recalculated for the printer.
7. Evaluate the delta E values. If required, continue optimizing, i.e.
reprint and remeasure the test chart. Stop when you notice that there
is no longer a considerable reduction of delta E.
