Digital BW, The Print

Thanks for the tip, Steve.

Used that workflow to print out a 21 step greyscale stepwedge at 
2880dpi using stock UC inkset with matte black on EAM. A stepwedge 
is, in my opinion, the ultimate test for greyscale output. The 
results were the best I've seen using the Epson driver but still not 
quite up to aftermarket dedicated black inksets (I've no experience 
using a RIP, IP5 caused my computer to crash). Wedge was neutral from 
45% to 100% black. A slight magenta cast from 30% to 40%, neutral 
again from 15% to 30%, very slight magenta at 10% and neutral at 5%. 
Viewed under tungsten light so I suppose due to UC ink's metamerism 
tomorrow morning when I move the print over to a window the magenta 
casts will turn to green casts. Pretty darn close, though. Thanks 
again.
