Digital BW, The Print

Steve,

I now use the MIS UT2 inks (with Eboni K) in my Epson 1270 with QTR 
(and IJC/OPM) profiles that exclude the Eboni K for printing on either 
Epson Photo paper or Ilford Smooth Pearl.  The Epson Photo paper needs 
no spraying nor waxing because there is no bronzing, but waxing will 
increase dmax and add more gloss (I prefer the low gloss appearance 
without wax).  Ilford Smooth Pearl has some slight residual bronzing 
that can be eliminated with just waxing, but the wax goes on easier 
after a preliminary spray (one coat) with PremierArt PrintShield.  I 
was using the UT inks in my 2200 for awhile and got similar results, 
but for now I'm back to the UC inks in the 2200 because the MIS 2200 
carts are just too unreliable (lots of cleaning cycles are needed to 
restore air blocked nozzles, which wastes a lot of ink and loads up the 
ink pad).  I understand that some new 2200 carts may soon be available 
that eliminate this problem and I may go back to using either the UT or 
UT7 inks in the 2200 when the new carts become available.  I gave up 
trying to use the 2200 with UC inks for printing on the RC papers 
because of the bronzing issues caused by the light inks (LC, LM, and 
LK).  The dmax numbers you cited below were without spraying or waxing 
and will increase significantly with either treatment.  I don't have 
any dmax data for silver prints.  I think that the UT inks (UT, UT2, 
UT7) give much better performance on RC papers than the the UC inks.  
Bronzing is less of a problem and it is easier to control tones with 
the UT inks.
