QTR and Color

2005-09-23 by chiron1961

Hi Steve,

---Good to hear you're getting the results you are after.  After Roy informed me that 
neither QTR, nor the Gimp driver, apply any undirected color management, I downloaded 
QTR, looking through it, reading the user's guide, it looked really good.  The next day 
when I went to print some PDN calabration tablets, my controls for QTR looked very 
different.  I printed one palette and got tones of eboni only ---no color.  Becoming 
impatient to produce a negative in the ball park on Azo, I returned to the Gimp driver 
because I am familiar with it, and more importantly, all my calibrations for Azo up to this 
point have been done with it.  Last night, I did finally succeed in printing two very different 
image files on Azo (G3) using the same systematically crafted process adjustment curve.  
The negs were printed with C and Y, no black ----and they showed no evidence of 
banding.  It took a small shift in chemistry and in the wet process and I achieved more 
than enough density.

Now I need to go back, extract and reload QTR and crawl into it again and learn how to 
use it.  Then I'll need to calibrate it to my process.  

I'll be back when I get into trouble.

Thanks for the encouragement and the willingness to assist.  I welcome your comments.

Kindly,

Nathan Jones
