Does this mean that if I use the same profile in Scribus and in Acrobat
that I should get similar results?

@Christoph - > What are the variables that you are talking about?  I
understand that there is a whole chain of processing that gets done during
the printing process, but that is completely invisible to me.  Is there a
web site that has a tutorial on this that describes the process?

What I'm trying to achieve is sending a pdf for a circular (flier) to a
commecial printer and have the confidence that the printed results will
match my intentions.  This printing company has a "Prinergy" setup that
does Gray Component Replacement, Sets total ink coverage to 280%, Black
Start @30%, Black Max @90% and Black Strength @ 50%.  At least that's what
the printer people told me.  I understand this only in a general sort of
way, but not really in terms of how it will affect the final product (which
is printed, but I've not seen a hard copy of).

It could be that I'm worrying needlessly about this.  It just seems to me
that if I send the printer a pdf that needs less tweaking by their print
system, then I will be more likely to have the results match my intentions.
