In the past week, I've profiled a few papers with the 225 patch target
and today started to add Extended Grays to the profiles. Since I'm
color-challenged, I read all targets twice and use the PFP Readings
Compare program in the files section to get each pair within a couple
of Delta-E.  After tossing a couple of incompatible papers, I've no
real complaints, but a question.

When looking at bars to the left of the MacBeth ColorChecker Chart in
the color test image, I was surprised that two matte-surface papers
had better resolution using the profiles built without the use of
Extended Grays, Epson HW Matte and Epson Watercolor.  If I didn't use
Extended Grays, these two had the best resolution of any non-luster
papers I've tried, but that advantage is gone if I include EGs in the
profiles.  Confusing.

Any thoughts?

Thanks
