Digital BW, The Print

Hello,
Yes I also have spend weeks and a box off 50 A4 sheets to get neutral 
results with GB but was not very successful because of the fact that 
under every other lighting the color shifts in to olive or magenta.( 
matarism) Good for Epson paper sales but not good for my purse!;-)I 
have downloaded the powerRip 2000 and just have done my first B&W 
test.
It looks much better so far. I only see a very small cast of yellow ( 
the water mark looks a bit gold)I printed on AM with color controls 
on. No ICC so far. Daniel could you make your RIP curve available to 
the group? And advise on your tests would be welcome. I wil do when I 
have done more testing. I wonder how your configuration looks like to 
print GrayScale with the Black and light gray together
