Color Management Guide
A third possibility should be tested if the first two are not the
cause of the imaging problem: a source color mismatch may
exist between the queue and the job’s input color space. For
example, if the intent of the job is to render a CMYK document
which was originally designed for a SWOP™ press, you need to
select “SWOP™ Coated CMYK” as the source CMYK color
space. If FOGRA Gloss is selected in Job Properties and
SWOP™ CMYK is selected in Queue Properties a mismatch
exists.
