Only if you have CMYK access to it, and know enough about CMYK settings to
actually improve things by doing this. None of this actually pertains to the
free drivers, as they are OS level, and will accept RGB only, if you send them
CMYK there is an uncontrolled converion to RGB from there that you definately
want to avoid. So profile as RGB. With the right profiling software and intent,
the results will have an excellent gamut.
