QTR-Quadtone RIP

There is definitely a terminology problem, which I think comes down to trying to use 2 words to identify 3 things:
1. icc profiles
2. QTR curves, which are really much more than curves which is why I prefer to call them profiles
3. an actual curve within a QTR profile such as a Gray Curve (which is either a set of input/output number pairs or a link to a Ps acv file), which is what I mean when I use the term curve

Unfortunately, the QTR interface uses the term Curve where something else might have been more appropriate. You get used to it after a while and realize that the term is used in 2 different ways. Maybe, at least in writing, we could use “Curve" (capital C) for the larger sense, and “curve” (small c) for the smaller sense. 
Does that make any sense?

PS - BTW, this is a thread from last summer, and I see I never responded to Calvin’s last post. Nor did anyone else. Are you still there Calvin?

I prefer to use the work "curve" for QTR's .quad/.qifd (.txt on a Mac) files and the word "profile" for an ICC file.  Otherwise the word "profile" is used for both and confusion ensues.  Keith used the term "ICC profiles" to make the distinction, but the problem with this is that it's all too easy for the "ICC" part to get dropped.

Learn to use the included profiles first, then move on to custom profiles if you need them. "
