I need an argument settled. A friend of mine is using a drum scanner and
is letting the scanner convert the file to CMYK. My recommendation was to
scan in RGB and let Photoshop CMYK setup handle the conversion process to
CMYK. My argument was for *better* control over the conversion process--
adjusting ink limits and control for dot gain depending on your final
destination device. I told my friend they only thing that needed to be
adjusted on the pre-scan was white/black point setting, but save it as RGB.
He replied that most of his settings were done directly via the drum scanner
including the CMYK conversion.

Ok. Anyone want to tell me the advantages of doing this conversion process
at the scanner? I told him once you're locked into CMYK, there's really no
way to go back. RGB provides more flexibility in the long run, since you
still have control of your conversion process at a later point in time.

IF you have no profiles available or made for both the scanner and the CMYK
output, then yes, possibly, the 4c on the fly scan, if tweaked properly by
someone with alot of experience could be the same or better than someone
who's profiled the works.
If very little adjustment per scan is done,and your friend dosn't use PS at
all then direct to CMYK could save a few seconds.
If you profile, you don't even have to adjust the WP/BP. You're right about
RGB being more versatile for output to well, just about anything.
