The Color / Image Quality Tabs
The Color tab allows for simple or very detailed color adjustments. For
many applications, Standard Color will provide a strong correlation
between Windows color (sRGB) and the output on the printer.
Fiery Expert Color settings (shown below) allow all aspects of the
image/content to be fine tuned. Custom profiles, rendering intents and
spot color matching can be applied here. For additional detail, please
refer to the Fiery Color Technical Reference, the Fiery Printing for
Windows (Mac) Reference, and the Fiery Print Options Guide on the CD.
