Digital BW, The Print

Jim,

Today I've been using the PS 6 Preview/View, Proof Setup, Custom
Profile/Tyler post method (all in a single function keystroke PS "Action"
now).  So far it's working very well and very easily.

Or maybe I was doing something wrong.

I can see where your procedure would work, but it involves a lot of extra
steps.  Try the method Tyler outlined and program a PS Action.  That way
there is no need to open and close files (and some of mine are huge) or go
through this stuff endlessly as you work.  Just open the file and hit a key
to apply the preview/custom dot gain profile, with no concerns about
inaccurate mapping to the RGB printing space.  It really works well as far
as I can see.
