Digital BW, The Print

Paul,

I didn't experiment with adding Eboni back in the profiles because the  
results were so good without it.  However, the initial trials I made by  
reducing 100% output suggested that eboni did reduce dmax beyond  
90-92%, but I don't know how much Eboni was actually being used in  
those tests.  I did some more trials with my "K-less" UT1 curves on  
several other RC papers, using the neutral 50:50 blend of the cool:warm  
curves that were developed for Epson Photo Paper,  and got the  
following results:

Epson Photo Paper - dmax 1.932 no bronzing
Epson Premium Semi-gloss - dmax 2.337 slight bronzing
PermaJet Oyster 271 - dmax 2.194 moderate bronzing
Oriental Graphica FB - dmax 1.529 slight bronzing, but mottling, very  
weak blacks, scratches easily
Pictorico Dualside - dmax 2.347 moderate to severe bronzing, warm grays
Ilford Smooth Pearl - dmax 2.328 very, very slight bronzing  
(essentially none)

Despite the lower dmax, I liked the appearance of the Epson Photo Paper  
prints.  This was the only paper with zero bronzing and the soft gloss  
did not produce distracting surface reflections - probably the closest  
to an air-dried glossy silver fiber print .  The Ilford Smooth Pearl  
would be a close second choice for me, particularly where a higher dmax  
is needed.
