But what's the dot resolution of the IRIS? Does it put 96pl of black ink on
1440x2880 dots in a square inch? That would be 32ml of ink to cover an 8x10
image. Something tells me they put out 96pl of ink because they have
somewhat lower resolution. If they're, say, 720x1440, then that would be
roughly equivalent to 22pl drops at 1440x2880.
