Fair enough. Note that I said rendering resolution, not print
resolution. An IJ printer (rip) advertising 720x2880 dpi print
resolution will typically render at 720x720 ppi (!) since very few
rips (or drivers) can handle asymetric rendering resolutions. That
means that sending data down at anything more than 720x720 ppi is
just a waste of bandwith and time, and it might actually result in
artifacts depending on how the rip handles downsampling.
I can certainly confirm that sending even as much as 720x720 to an
Epson is a waste of time and bandwidth. It actualy produces less
detail. I had a student who thought that 720x1440 meant she had to
send a 1440-ppi file, and was wodnerig why the results were hideous.
But there are a lot of variables, the paper being a big one. (I have
found minute differences on Epsons printing to glossy paper at
720x1440 and 720 x 2880, but they're only detectable with a loupe.
That and the fact that the latter takes four times longer to print
also leads me to believe that the epson driver is doing something
with that asymmetric resolution. Whether or not it's worthwhile is
another question entirely. On matte papers the higher res in one
direction seems a total waste of time.
