Digital BW, The Print

Paul, looking at your diagramms in this paper, I suspect that I 
wasted my efforts last weekend. I was trying to create neutral QTR 
profile for PremierArtBW for 2200 using UT7 inkset. On glossy and 
satin papers, and on some other matte papers with UT7 I was using 
identical curves for M and C, and for LM and LC to get neutral tone. 
Whatever I try on PremerArtBW, I always have one tone (cold or warm, 
mostly cold) dominating. To compensate, I set limits for cold and 
warm inks 3-4 units apart, and still cannot get neutral tone. Sounds 
like this paper is quite unique in its response curve, it may be 
possible that I have to use curves with quite different shapes for 
warm and cool inks.
PremierArtBW shows quite dramatic difference in response to warm and 
cool tones, so may be UT7 inkset doesn't work as designed?

Thanks,
Sergei
