Use embedded profile
You can specify whether the Fiery server uses the source profile (either RGB or CMYK or grayscale) that is embedded in the print job rather than the source profile specified in the print settings.
RGB
If you turn on Use RGB embedded profile, the Fiery server ignores the RGB source option and uses the RGB profile embedded in the print job (if any) as the RGB source profile. If you turn off this option, the Fiery server uses the profile specified in the RGB source option.
CMYK
If you turn on Use CMYK embedded profile, the Fiery server ignores the CMYK source option and uses the CMYK profile embedded in the print job (if any) as the CMYK source profile. If you turn off this option, the Fiery server uses the profile specified in the CMYK source option.
Grayscale
If you turn on Use Gray embedded profile, the Fiery server honors the embedded grayscale profile information for objects tagged with a grayscale profile and uses the source grayscale profile for gray objects without a grayscale profile.
