Jenny,

I hope this does not sound too complicated. But there are ways of 
doing this with QTR.

If you want neutral highs, your pbservation is correct that using the 
lightest K7 ink may not be sufficient, as the overlap between the 
next density CS will dominate. So the best thing to try is to use the 
following inks: (1) Black, (2) Dark CS, (3) Medium CS, and (4) Medium 
K7, and (5) Light K7. When you create curves, make sure you set (4) 
to copy curve from (3). Now you should get a more seamless transition 
of hue from the high-mids to the highs.

Still another alternative is to use the follwing commbination of 
inks: (1) Black, (2) Dark CS, (3) Medium CS, and (4) Medium K7. My 
gut tell me this will work better from a hue perspective. When 
creating curves for this setup, make sure you type in a LOWER than 
true density for (4), and a HIGHER than true density for (3). This 
will force QTR to partition these inks in the split way you desire. 
The rest you will have to play with ink limits. You will have to 
REDUCE inks limits on (4) and INCREASE limits on (3)

Good luck. It can be done. I know, because I have done it with QTR on 
a 1280. The exact look, well that in your eyes, I hope you find it.
