Digital BW, The Print

Thanks for the replies John and Paul ..

Paul,
I should have added that I use qtr with Carl Schofield's 3pkn
profiles. I edit and print in gamma 2.2 16bit. I used to use the ps
curve you linked to, Paul, when I was printing 3mk, which was what I
did the last year or so. I'll try the curve on a test print tomorrow,
but I have tried similar ones with unsatisfying results.

My workflow is: edit in 16 bit gamma 2.2, flatten, resize, save tif
16bit with profile, open in qtr(2880dpi, unidirectional, curve1
3PKN-IGS-GL,) print.

I might be doing something wrong with qtr, do I have to use all the
files in Carl S.'s /R1800_3PKN.zip perhaps? So far I just added the
quad files to the qtr quadtones folder, and have not used the others.

I'll have to read up a bit more before manually adjusting curves all
by myself... but it seems like the most probable cause for these tonal
effects right now.


sincerely,
Espen
