I have been a member of DDAP (Digital Delivery for Advertising
Production) and the Digital Ad Lab in NYC for many years. One of the
things that has come out of many debates at these meetings is that one
should NOT prepare files to match a particular press, unless you work at
that particular printing company.
The approved procedure is to match SWOP specifications. As someone from
RR Donnelly pointed out, "We have 384 presses. How do you know which
press we are going to run your ad on? It's our job to match the SWOP
standard proof on our presses."
Profiling for particular presses, unless you REALLY know where the file
is going, just contributes to entropy.

Subject: Re: CMYK output profiles & dotgain
The one area where profiles may not compensate for dot behavior is in
the transition zone from minimum printable dot to paper white-it
depends on the target that was used to build the profile, and the
press behavior.
I find that it's best to determine the minimum dot the press can
hold, then manually set detail white to that dot value, letting
specular whites blow out to white paper.
If the profiling target has a rich set of patches in the highlights,
you may not have to do this, but if it was built from an IT8/7.3
target, you almost certainly should.
