QTR-Quadtone RIP

thanks, this is what I presumed.
All I wanted to do was get some nasty spikes out of the toner channels down near 100% in the existing curves I've been trying.
They are only a problem with some of the PK setups, giving less than ideal gloss differential performance between 90 and 100%.

Regarding creating new raws, should the base file used be rgb-raw-16.psd? It looks to me like the existing raw toner files have been rotated 180% from that.
Does it matter?
