Digital BW, The Print

Hello Nick,

I reviewed the paper curve information I had, and reread all the 
densities on the ink calibration chart printed at 75% (darkest black) 
and got the same numbers. I then redid the curves and linearization 
(the old lines were deleted before doing this) and printed an image 
which had been converted to LAB Matte using the files from Roy as 
gray workspace/printspace. The result was still too light compared to 
a UT2 paper curve created using the same method. I now am thinking I 
need to change the gamma on QTR to print a darker midtone section. 

This is the .quad file information that appears to look OK. One thing 
I do need to understand is if any of the inks need to be designated 
as Toners or not. If so which ones?

PS. I just printed the image using =5 gamma and it looks much better. 
What a difference just that one single adjustment makes. Hooray, now 
I can use that old ink and not throw it away.

Your friend in Photography,
