Yes, if you use a good up-scaler like lancos within qimage
(ddisoftware) then you can add sharpening and other things to the
final output before sending to the printers.
Personally, I find its easier to work out what the printers can
handle, then up-scale before sending, with qimage (and no I dont work
for them, lol) its quite often better than most printers RIP software.
