QTR-Quadtone RIP

I'm getting lower dmax than for matte, but if I push it too far (60%),
QTR won't linearise, and if I back off part way (55%) I get the bumpy
curves.  50% seems to give a reasonable compromise.  I may still be
able to get lower dmax with these longer drying times I'm using now.

Are you really linearising your curves?  I find it hard to believe
that the curve creator is able to linearise with that sort of shadow
compression and "inversion".  And if it did somehow, surely there are
blocked up shadows alongside your open highlights?  Probably blocked
up midtones as well.
