Before the higher deities wake up and wade into the deep end let me
just get 64.6 cents (one Canadian dollar) in.

The RGB settings are Adobe RGB working space, Apple CMM engine, no
black point.
While the Apple CMM is a nice one, many of my readings here and
elsewhere and testing confirm the Adobe ACE is a more versatile
choice for image work, BPC an individual preference, however; in
profile work I tend to leave BPC on in my color settings and choose
it's use when doing actual Convert-to-Profile functions. If I want a
preferred CMM and intent applicable to a particular profile I set it
in the profile using Steve Upton's Colorthink (profilecity.com) 1.1.
Some vendors give me pretty good results, 50 percent or higher give me
results that are awful.
One recent vendor gave me a contract proof that was so magenta I thought
the tiff file was corrupted.
The most populous portion of our operation here is pre-press. The
fine art division (me) is the only work station(s) utilizing
ICC-based color management. Hired on the basis I knew what Colorsync
and it's implied workflow theories were I dusted off the
pocket-protector, put on my colorgeek cap and demonstrated time and
time again how to manage color-managed files in and out of various
applications (even to a older PantherRIP). But the same 'CM-off'
standard kicks in anytime anyone runs into anything which requires
thinking beyond CMYK in straight percentage values or stumps me with
a question I can't answer.
You have to educate. A good place to start and the best way to finish
is by rewarding those who manage your work well with more work.
You should consider by the information provided you are going to
press from an RGB-based workflow. The transforms down the line
seriously affect your results, especially if you are handing RGB to
someone who converts everything to an undesired CMYK (possibly
through other applications too) or doesn't even know what a profile
is or what happens in the background to a file which looks ok on
screen. If you know the type of press, ink total, dot gain, etc., you
can build your own press (simulation) profiles, do your own
conversions and tape instructions on the operator's screen how to
open an embedded file and print to SAS space out of PS6but the ideal
is to have an actual output profile space to transform to.
Am I doing something methodologically flawed, or is this whole ICC work
flow thing a joke?
No. (My client base is growing as a result of ICC.)
What can I do to help insure quality results from a
variety of press houses.
Stick with the program. Learn more, teach more, demand more.
Stay tuned...
