I reprinted an image from the CMYK digital file used by a newpaper the other 
day, and found details in the inkjet print that the 100 lpi original missed 
entirely. I'd say you would need to get well above 200 lpi to match the 
detail in the stochastic dithering in any 1440 dpi Epson. I found it 
interesting that the CMYK press conversion applied at the scanner for the 
newspaper was so limiting in the photo above that I could barely improve on 
the original newsprint version color-wise; any significant attempt to tweak 
the curves created posterization or dark colors that were out of balance. If 
I had the original photo they had scanned I could have easily done a better 
job making my own RGB scan for Epson output. So I ended up with slightly 
brighter colors, a bit denser black, and a bit more open shadows, but no 
drastic improvements, as the seperation was in the colorspace of the press, 
and just didn't contain significant info for improvement.

I'm spoiled by RGB process...
