Digital BW, The Print

Bert,

Roger Clark and others could tell the difference between 300 and 600ppi in 
blind tests:-

and he puts the resolution of the human eye at between 700-1000 ppi

Printing with a 2200/2100 at 2880 can certainly resolve lines at 600 per 
inch, but if you haven't got 20/20 eyesight, you won't see all the detail.

I have no experience with the larger printers, but I have looked at my 2200
output with images from 240 to 720 DPI and I see no difference. I haven't
used a 10X loupe, but I don't expect people looking at my prints will be
using one either.
