Re: Create ICC Soft Proofing question . . .

2005-10-24 by Tyler Boley

I should keep my mouth shut because I'm not real up on create icc, but
I think BPC is built in so is always on? The other options like paper
white can be used at will depending on what is most useful at the
time. I think it's washing out your blacks because "black ink"
automatically comes on with it by default. I find it bears more
resemblence to the print on than off, but the initial shock when
turning it on is difficult. Turn away when switching it on, and come
back a minute later, it'll look more acceptable.
Regarding which output to profile, Ernst's post was most revealing.
Despite my arguement earlier than in a hypothetical sense profiling
will equalize out various initial settings or linearizations, it's
best to find a setting that prints as closely as possible "same as
source" as it will when printing with a profile. The first reason is
that it minimizes potential tonal loss. Secondly, the less work the
profile conversion has to do, the better job it will do. Lastly, it
sounds like CreateICC has trouble with reversals, so at the least your
output should progress from light to dark even if gamma is off, as you
suggest. Regarding other problem papers, you might want to play with
media settings as well.
