Digital BW, The Print

Maybe an “expert mode tag” in the text file to override the BP to a specific
L* value?

Best regards,

Bob,

The quote from Bruce Fraser was very useful.  I also like a later paragraph
after
describing the various Simulate options:

"An obvious question is, which of these three simulations is correct? The
truth is, all of
them are, and none of them are. No proofing system has ever provided a
perfect match to
the final product: We learn to interpret proofs, and therefore, like any
other proofs, you
have to learn to interpret the soft proofs offered by Photoshop. Each one
tells you
something slightly different about the way the image will appear in print. A
handy rule of
thumb, though, is that for glossy stocks, the default view with Paper White
and Ink Black
unchecked will be the closest, while for uncoated stocks, the view with
Paper White
checked will generally be the most accurate." -- Bruce Fraser

I think this is especially important to note -- you must get used to a
particular
soft-proofing setup and learn to judge it.  I suspect that I am fairly used
to the black
not changing i.e. not dulling down but that doesn't make it more "right".

---------------------

The forward profile I think is pretty fixed -- it has to match
white-to-white and black-
to-black.  Its the reverse profile that can be done in various ways.   From
reading and
trying variations I think the white end should be "illuminant white" this
makes the
default white of the print show as the white of the monitor.  If you were to
set it at the
actual white the result would be the same as Simulate Paper White so the
checkbox
would do nothing and there would be no way to see monitor white.   The black
end
is currently (2.3.2) set at the actual black, but the internal BPC by
default maps this to
monitor black. (Note this is not the BPC you see in the dialog which
controls the
forward BPC).   The using of Absolute in the reverse profile would explain
why the
two checkboxs Paper White and Ink Black are linked.  Although it seems to me
they
could have uncoupled it.

I also tried mapping the black end into monitor black rather than actual
black in the
reverse profile.  This is basically doing the BPC in the reverse profile in
the tables.
This allows the Paper White without Ink Black option but of course you can't
get the
Ink Black at all since it's already been removed.

Putting the black end somewhere in between the actual and monitor black is
an
interesting idea.   It might be a compromise between the optimistic monitor
black
and dull actual black.
