QTR-Quadtone RIP

I am trying to set up my 2400 using Cone Color Inks on Enhanced Matte
to print B&W with QTR.
After determining an ink limit of 55% I measure the 2nd print of the
calibration target using this ink limit of 55%. The max density of the
LLK measures density 0.46 which matches about 29% on the LK strip. The
LK max density measures density 0.99 which matches 33% on the K strip.

If I plug in these values the graph of the different inks looks very
jagged where the LK and LLK overlap and the print looks bad. If I go
ahead and linearize these values the curves look even stranger and the
print is even worse.

Any ideas on what is the problem.

Thanks for any help.

You should put density of LLK as a percent of K (Not LK). It should be 
somewhere in the 10% range.

Good luck.

Thanks so much, that did the trick. I wish that someone connected to
QTR would sit down and write a comprehensive manual and then keep it
up to date. Not the esoterica of the program or various workflows but
a good solid explanation of the features and where and how to start.
Ther esoterica could be covered here. That's my two cents, thanks again.

Cheers,
