Digital BW, The Print

I'm wondering if anyone is using Margulis SWOP coat settings for 
their printing with Photoshop vs. just using canned profiles.

My simpleton understanding is this might be an area to assist blacks 
and metamerism (at least in shadows) with grey color replacement.

Admittedly, I need to re-read, probably several times to comprehend 
but your input is desired.
