What may not be evident is you can also make a proofing setup for

That's a good tip for users who only link the RGB working space and
the monitor space while editing. But one step further down the road,
I kind of doubt this is the best way to work, now that we have RGB
working spaces that support more ink sets than monitor size RGB
working spaces (: ColorMatch RGB, Apple RGB etc), and some that
support the full scanner and camera RGB space (: EktaSpace,
ProPhotoRGB).
The classical Linocolor way of working is arguably smarter. The
concept here is that you actually finescan into three channels, but
color correct to four to make sure that your finescan separates well
to your choice of typical print production process.
So what you do is this: Start with the full scannerRGB film space,
chain the print production space to compress the gamut you can't see
on the monitor anyway, and then link the monitor space so it hold has
to hold as much of the print production space as a monitor space is
able to, and not the full scanner or camera space. IOW edit in CMYK
simulation mode, rely on the perceptual gamut mapping in the printer
profile to manage the colors you can't see anyway, and concentrate on
what you can see on the monitor and the proof prints you can pull off
your large gamut PostScript inkjet.
You can edit in Lab simulation mode in Linocolor, of course, but this
means that the full gamut of the scannerRGB film space is matched
with relative colorimetry to the much smaller monitor RGB space. This
creates the same problem as in the RGB to RGB chain in Pshop.
Simply adding SWOP TROO1 or ISO 12647-1 to the profile chain in Pshop
6, but staying in four channels now that we can do so, is a way of
handling the WYSIWYG problem with huge RGB working spaces.
It's the sociology of the two workflows that creates the anxiety over
non-WYSIWYG colors. Linocolor users start off by chaining the print
production profile as a matter of course, Pshop users chain the print
production profile as it were as an afterthought.
Maybe there's a more elegant way of phrasing this, after another coffee -:).
