Digital BW, The Print

Hi Paul;

Having 2 or 3 different mulit-ink curves that mix different cross-
over points is  more effective at hiding flaws, no doubt about it. 
but a couple weeks back when Clayton was working out a 2K curve to 
get his R200 going again, we noticed that even if the 2 Ks were 
identical in slope, having them contribute a siginificantly different 
percentage to the overall quantity seemed to help  a bit with the 
microbanding. 

Of course if Epson had chosen to manufacture this printer to the 
standards of, say, the 780, ($79.00) or the R200, ($90.00), or even 
the R300 (180.00), we would not be having this discussion. It will be 
interesting to see how it goes with the R1400.
