LAB Values out of Order - QTR

2006-09-29 by Walker Blackwell

Hey everyone. I'm experimenting with a 101 patch setup in QTR and I'm creating a Piezotone 
curve using K1, Selenium K2, Selenium K3, and WN K4.  Of course, this is throwing my "ab" 
values off but L is still showing up fine. I'm wondering if there is a way to turn off color-
valued linearization and just focus on L/density in QTR so I can actually linearize an 
environment that has a split tone with more than just 21 patches. Even 21 patches is a hit-
and-miss for large splits like this. 51 would be fine too. By looking at the L values, seems like 
QTR is really only dealing with 51.

My TXT in and out files are at: http://www.blackpointeditions.com/files/print_environments/

take care, Walker Blackwell
