Clients often like to see a match to the paper
they’ve chosen for their project. Hard to argue with that really.

off the simulation is something I generaly disagree with,

the client just doesn’t like to see dots in the non-image area

loupe. That will lead me into discussions of accuracy with them.
Nothing wrong with doing general proofing using the white point of
SWOP3 (or
5 or Gracol 1), but our clients have always requested a closer white
point
simulation of the actual paper in use ..for the fact that it does
improve
the visual match between proof and press sheet.
Of course it all depends on the context in which the proof is
generated. I agree that matching the color of the actual printing
stock is more desirable than just matching a spec such as SWOP. For a
Kodak or FinalProof you can usually proof ON the actual stock, which
is even better. However, this all assumes you KNOW what stock the job
is printing on. As a printer, you usually do know. As a photographer
or retouching house, you usually don't. When the final stock is
unknown, or images are being prepared for multiple uses, it is very
useful to use a know spec like GRACoL or FOGRA39, because this is a
"neutral" visual appearance that everyone can agree upon. If I just
eliminate paper simulation and go to the color of the proofing paper,
then I'm NOT going to the spec.

As for the difference between the SWOP3 standard and the actual
paper used in your publication, well, the SWOP3 reference is
obviously not the one to use. If you cannot find an "off-the-shelf"
reference profile that is close enough you might consider editing
the white point of a standard profile of the same type (e.g. coated
web) to match your press substrate.
This assumes that the proof is being generated by the publication or
printer. If I am a repro house or creative agency, when releasing ads
to publications, it's not really feasible to try to determine the
actual color paper of each individual publication and then build a
separate proofing queue for each one. We often have to release the
same creative to dozens of publications at once. If we have a separate
proofing look for each one, clients are quite likely going to want us
to make color adjustments to get them all to match the "approved"
color. Release schedules are usually just too tight to allow for this.
By going to SWOP3 (paper white and all), we can get a fair average of
the paper for most U.S. pubs. Beyond this, most U.S. pubs now state
right in their specifications that they want a proof that has the
IdeAlliance control strip and is certified to SWOP2006_Coated3.
