Fine, but the way it's done I'm not so sure. 
I'm having a desperate time trying to properly output MPS K7 on glossy 
media. 
I somehow managed (finally) a proper linearization using the 51 
stepwedge, but when the profile is created and used with percep. w/ BPC-
on in CS3 to convert the piezography.psd target, the 
100/99/98/97/96/95% patches get clustered together in a 
100/99/99/99/98/98% ramp given a L*14.5 Dmax. What this leads to is a 
blocked shadow area at the end of the greyscale.
Perceptual intent compresses the tonal range but here the compression 
is very agressive.
