QTR-Quadtone RIP

I did do the reduced modification of LC=LM=20 and it is about perfect, maybe slightly 
blue and a bit dark compared to the Epson driver.

Will next reduce LK a bit as you earlier suggested.  If that isn't perfect, will try the mods 
you suggest below.  I suspect that a bit less LK will make it great though cuz it is so close.

Interesting how ones opinion can change:  I had thought of the Epson driver print as very 
cold; now it looks a bit warm compared to LC=LM=20 with the "20" print being cold 
neutral.

or is the Epson cold neutral and the "20" print a bit blue?  sigh...

will take a bit of relooking as time passes to decide.  Both nice though ("to date")

Thanks
Scott
