Actually just saying it is a mess and discussing it comes up a bit short of what really CAN be done:
- Someone who feels sufficiently competent, write a hint that
describes an intelligent approach to using RGB, CMYK, and ICC in a work flow. 2) Each person who has access to the hint and regularly uses the same print service could discuss with someone at the service what they mutually know about implementing such a work flow. 3) After said discussion, perhaps the printer could be persuaded to publish the work flow, or their local modification, to their public web presence. This need not be the front page or any page that is readily found, but somewhere a customer who understands the issue could be directed so the shop and the customer could bring their work flows together.
If this is done often enough, the knowledge will become "Common".
Amen to that :) Any takers?

The physical printing press will either use spot colors or the process colors of CMYK. That is the target. That is how modern printing presses work. They mix those four colors and not Red Green and Blue. So I suggest:
1. Use CMYK from the beginning to develop a print document. This gets around the smaller gamut problem.
2. For exact colors don't depend on a monitor representation, calibrated or no. Take the CMYK values and look them up on e.g. Galaxy Color Gauge Color Pro. This still won't be "exact exact" but it will be the closest you can get without having the printer produce a proof copy.
As my father used say, don't fight the problem. Printing presses use process colors AKA CMYK. Work backwards from that.
The software products Photoshop, Scribus, Krita, InDesign, TeX, Open Office etc. all can work in and produce a pdf file with CMYK generated colors. So they solve the problem insofar as it can be solved. Inkscape needs to be added to that group IMO.
