Matchprints have a lot more range than the press or an Epson so let's
re-phrase that to "a Matchprint simulating press". Good prepress houses
correctly run their proofers like FujiArt, Matchprint, Polaroid, Kodak etc,
to simulate the paper on the press , however some think that making a pretty
designer proof as Bruce would call it letting the black run to L2 and
brightness the highest possible on the substrate.

See the posts by Terry Wyse and Bruce. I'll add that the variations can be
large in magazine printing to the point of the price of ads are adjusted
according to the output quality at printing time. I'll give you an example;
L'Oreal ad Marie Claire magazine. Normal page rate $20kus. Printed a little
light, losing highlight values; $15k. Printed too dark and red>$10K. Printed
without contrast and green skin tones; free and actual credit towards the
next media space.

You see it is possible depending on the press. When I have the rare images
going on a sheet fed press the results are so close that you barely look at
the final print because it is exactly as intended. When on a rotary press it
depends on the imposition AND paper. On gravure printing seems like hog
tying an elephant. These of course are my biased experiences from the
supplier side and it's certain that printers have their set workflows that
do work for them.
