Digital BW, The Print

Hi Susan;

I don't know the exact volume of ink in the lines of that machine, 
but I measured the 7600 at about 20ml per damper/line. Even at half 
that, repeated switching would be time consuming and expensive. If 
you need to do both color and B&W your best choice might be to leave 
color inks (either UC or MIS equivalents with Eboni K) and run the 
B&W with QTR. There is a good selection of curves available for the 
4000, and you can make some pretty fair ones yourself without a 
densitometer. It wouldn't be as  smooth as the K7s but considering 
the fine dots and high dither available, you would still get some 
very good results.
