Custom Curves

Custom Curves

2005-04-16 by sauganashkid

I find the HELP information jargon on CURVE CREATION in QTRgui to be 
generally incomprehensible. Not that it would do me much good even 
if I could understand it because I don't have a densitometer or 
spectrophotometer which I believe are essential tools required for 
creating accurate curves

I do essentially all of my printing on an Epson 2200 with Epson UC 
ink and either Epson Watercolor Paper-Radiant White or Velvet Fine 
Art Paper. Using either of these two papers and the canned curves 
that came with QTR in the combination 70% UC-EEnhMatte-coolSe and 
30% UC-EEnhMatte-warm I get what I consider to be acceptable quality 
neutral tone ptints. What I'm wondering is, could I do any better if 
I had custom made curves specifically generated for the two papers I 
actually use in place of the canned curves for Epson Enhanced Matte 
Paper? Is there any possibility that the family of curves that came 
with QTR will be expanded in the future to include Velvet Fine Art 
and Watercolor Paper? Is there any one who has created custom curves 
for these papers who would be willing to share them with others who 
for one reason or another aren't capable of doing the job for 
themselves? Is there any particular place one can go to to find 
other custom curves that can be downloaded and used with QTR?

Donald, you must have read my mind because I was about to post the same question on this forum.  I really hope someone can provide some answers to the issues you've listed as it would greatly help me as well.
