The next curve starts before the peak of the lighter one. You'll often see in in the QTR "Show Curves" graph that there are actually two distinct turning points. Only Roy knows the algorithms he's using, but when that first distinct turn-down in the positive slope of the light ink starts is probably where the darker ones starts. You can to into the *.quad file and see for sure if you're interested in the exact point.

Paul,

OK, this is me, slapping my forehead… duh!
It’s not like I’ve never seen one of these before. I’ll use tunnel vision as my excuse, OK?

Anyway. Looking at the curves, would I be correct in thinking that the peak of each curve represents the point where that ink has been set to take over from the next darker ink? In other words, how is the positioning of each curve determined in relationship to the previous curve?

Show curve" function in the QTR Windows GUI is very helpful.
