Digital presses are something of a different (color) bird from "regular"
presses. One very frequent problem I see with folks sending files to a
digital press is that -- typically because they're not aware of how defaults
can kick in on them -- they end up sending a SWOP CMYK to a digital press.
But a digital press is far from SWOP. The dot gain is very different --
close to nonexistent. The pigments are far from SWOP, and require fully
separate curves. And, the gamut of a digital press tends to be much wider,
part due to the digital press's ability to hold more toner without typical
press issues of wet trapping.
Many of the default profiles for digital presses are very good and, as we
might expect, heavily optimized for device space. Here's one time when a
wide-gamut RGB file (Adobe 98, for example) will give the press enough data
and gamut to "do its thing" well. Try that for starters.
