In that case, I suggest supplying your clients with .csf files for
the adobe apps, and include your proofer profile.
Way more important than the choice of RGB space (because apart from
the huge ones that you don't want to put in the hands of the
clueless, they all clip some printable colors and all contain plenty
of unprintable ones), is the ability to soft-proof to the
destination. Supplying your proofer profile as the CMYK working
space, and telling your clients to work with CMYK simulation turned
on, is going to do a lot more in terms of avoiding surprises than
choosing any particular RGB working space, because the user can see
the box of crayons they have to play with.
Supplying a .csf that has "Preserve Embedded Profiles" set as the RGB
policy would also make it a ot less likely that you receive untagged
or mistagged RGB.
My $0.02.

Mike,
At this stage in the evolution of the industry, I'd have to say that
the only rule of thumb for supplying RGB is, don't even think about
doing it unless you have an ironclad guarantee from the recipient
that they know how to handle it.
If the recipients know how to handle it, any profiled RGB space
should work just fine. If the recipients open supplied RGB in
Photoshop 4 and convert to CMYK on default settings (which is way
more common than one would hope) all RGB spaces are equally dangerous.

Thanks for the info: I'm sorry if I confused anyone; but we are the
recipients of the rgb files. Our workflow consists mainly of ctp to
printers throughout North America and Asia. Thorough testing allows us to
supply contract proofs either for North American standards or Asian
standards, and to date we have had very little problem with the press
matching our supplied proofs. However; at times when we supply an interim
proof for sign off the designer or photographer may say what we all have
heard before "Why doesn't the proof match what I saw on my monitor". I
don't have problems answering that one; but I believe a lot of those
problems can be overcome with communication at the appropriate time
(before the job starts). If we could begin with a set of "supplied rgb
rules" for all designers and photographers that would be a step forward.
Soooo - do they embed 100% of the time, and NOT in monitor space but in
sRGB or such? Do we advise on things such as royal blues going purple, or
do we quietly fix it in cmyk behind the scenes? If at all possible I need
to be in control of the conversion because of UCR, press type, stock,
etc. That is why I would prefer images supplied in RGB if at all
possible. However, so as not to disappoint the client he should abide by
at least some rules. It is those rules that I am after. Something clear
and consise; something that will not turn off the client; something not
too overwhelming. Sometimes clients when confronted with heavy duty
technical "stuff" would just as soon go somewhere else. It is such a fine
line. Hopefully I have explained myself.
