I use it in most all art paper profiles, meaning both matte art papers (and 
any other matte papers, for that matter, but all my matte papers are art papers 
<G>) and the new "gloss art papers", meaning Silver Rag, F-Type Gloss, etc. 
This really has to do with the difference between gamma 2.2 and L*. If you 
print a Gamma 2.2 gray ramp, read it, and graph the L* values from your Lab 
readings, the shadows appear clogged. If you run the 5 point adjustment, it fixes 
that clog. Of course, the clog wasn't there in the first place in gamma 2.2. So 
an L* workflow might fix this in advance. But whatever the cause or percieved 
cause, I prefer the more open shadows in both color and B&W, and I usually use 
the same profile for both anyways, so the adjustment applies to both. Sorry 
for the tangent... <G>
