i have found using the v.2 profile for hardware and software gives me the
rgb that is closest to my screen image.  here's the link:
http://www.color.org/srgbprofiles.xalter.  you may not be able to get to
this page directly, because there is an acceptance page you have to go
through first.

sometime back there was a very good discussion on color management and
hardware profiling.  you might want to have a read.  the topic was "how to
use color management" in the archives.  it is very enlightening.  but for my
purposes, the srgb with no black point scaling works for my soft proofing.
getting the cmyk profile from your commercial printer would be a good
thing.  it puts you in the ballpark.

good luck.

cheers,
dwain
