Not much indeed, but I use the (noisy) hair-dryer method. Currently 
I'm trying to fix MPS with a R1800 before moving it to an LFP.

I'm trying my luck with QTR because of the R1800, I'd like to produce 
something even vaguely ressembling Jon's curves. With SP I saw your 
talk about the creation of a spot color : SP let you do that without 
having to linearize it ?
For underinking, as I said I just use a bit of the lighter dilutions 
to help me separate shadows while still reaching Dmax at 100%.

I know you're mostly right, I just hate the idea of re-loading the 
print.
