I see a lot of good suggestions here and I believe Rich Apollo's
advice is spot on. A grayscale will do just fine for publication
magazines. There is no real need to introduce the CMY inks if all
you're printing is a B&W image unless you can't live without that
extra boost in density. Sure, the proof has be SWOP standard, but
the images can be a 20% or 22% grayscale and would be perfectly valid
for SWOP specs.
However, if the images are mostly neutral but have some color
elements in the pictures, you may want to take Terence Wyse's advice
and experiment with extreme K separations.
We use an extreme K separation profile for publication printing of 4C
neutral images and the idea is very similar to Terence Wyse. However,
I set the black start point very early in the separation and then
aggressively curve the black upwards in the midtones using a Heavy
GCR setting. The result of the separation should be nearly identical
to Richard Booth's method but far less labor intensive. We have had
excellent results with this profile for two years running.
Email me if you'd like a copy of my profile but for best results I'd
build a new Extreme K profile from GRaCOL. Cheers!
