I own a prepress company that finds ourselves in this situation all too
often.
Submitting an rgb image to a separator is only a bit further along than
submitting a chrome. It still has to be color separated and proofed on a
standard printing proofing system.
Submitting RGB requires that you have pre-arranged agreement with the
prepress vendor to color manage your work. Don't just assume that will
happen.
My conceren as a vendor would be mapping the image from your Fuju to my
prepress proof.
While this can be done with good results it can also still leave some
color correcting to be done to get an exact match. You would be expected
to pay for the time and additional proofs to accomplish this.
I don't think "this whole ICC workflow" is a joke but I do see it
setting unrealistic expectations. There are many differnces between
proofing systems that can't be compensated for even with color
management.
For example, hue variations in the primary colorants when dealing with
pure color items. It's very difficult to reproduce things like bright
colored flowers that need pure magenta when the two magentas are
different. If the color is not in the destination color space, it's just
not going to happen.
You should ask the printer if they have ICC profiles of their proofing
systems. This will make the situation better but still has issues.
The person who converts the image to CMYK has the final responsibility
for how it will print.
In theory, if you take your image from your working rgb to your fuji
and I take it from your embedded rgb profile to my cmyk output, the
color would be the same.
That's the theory. As one who has been there many times I can tell you
it has only marginal success.
