Digital BW, The Print

Roy & Paul,

I tried the UT1 inks with Eboni K in my 1270 using a neutral curve in  
QTR and printed to Epson Photo Paper.  The Eboni rubbed off and showed  
a gloss differential only in the 100% patch.  However, by applying a  
curve adjustment layer and limiting output at 100% I was able to get  
rid of the rub-off and gloss differential.  The "optimal" 100% output  
limit in terms of dmax was at 92% and there was no rub-off or gloss  
differential.  Print looked great with no bronzing either.  Dmax  
numbers (see chart below) were not that great but the blacks still  
looked good.  I did no spraying with Print Shield for these tests.  I  
wonder if more C position gray ink were laid down under the Eboni if  
dmax would be higher.  Roy, could this be accomplished with a higher  
GRAY-OVERLAP?  I was using 10%.

95	1.609
