I'm surprised about the rgb demand. I haven't had any photo engravers yet
who use three color space files correctly. The only way to limit risk on a
three color file is to send it in self defining Lab , even if the possible
range is altered. Asking questions about how their chain is colour managed
and how outsiders could fit in will be upsetting to them in any case.
Whether or not a profile is included is something you don't have to ask,
rather just send it embedded, and in tiff. If you send EPSf with profiles,
they may be rendered inadvertently in their rip with an unexpected color
rendering. If you send without embedded profiles , it shouldn't change
anything, as , you're sending CMYK that will be process as per their CM,
even if it involves transfer curves on a CTP setter. IF their printers run
the presses to Brunnerscale, Fogra, Dupont , or other standard densities
your file will come out as it was intended.

I once hand measured all the solids off the color bars on Madame Figaro and
entered the Lab numbers in Photoshop , later saving it out as a profile.
E-mail me if you'd like it. Their press densities are all over the place
though and from one week to the next the densities change a lot. Again
reason to separate for a standard or proofer , preview (softproof) their
press and hope that it'll be well printed.
Yes, exactly. If you separate for EuroscaleV2 and they are running to the
above mentioned densities, then your soft proofing will be characteristic of
the other images on the run. Of course this will vary from slightly to
enormous colour differences on press compared to the idealised Euroscale V2
but that's the reason why it'd be nice to have profiles for their presses
even if for only soft proofing.

Hopefully better.

Let's look at the disappearance of scanners. When everyone is digital then
they will have to get their act together. Now it's all to easy to blow off
photographers as most of their source imagery is still film. Some big press
shops have internal workflows that could be adapted to outsourced ICC jobs
yet they are making hard to find details or good advice for their own
presses. Possibly Ifra have made a lot of progress here in France, and I
think Quebecor too. Always strikes me as easy enough to change for the
better, yet blocking progress is a major obstacle for ICC CM to tackle with
these stubborn players.
