The drying time for the ink between each stroke of the printer is longer
when the print is larger. The chance ink will bleed gets much higher on a
6x9 print. The 2880 dpi shouldn't chance that or make it worse as (to my
surprise) the higher the dpi the more ink is used in Epsons. There's one
thing that slows down the printer more or less relative to the image size
and that is the time the head has to stop and reverse its direction between
strokes. If you place four 6x9 images next to one another and print them in
the same way you printed one 12x18 image and you still get better quality
for the last then you can throw my theory in the waste basket. There will be
detail lost on a 6x9 and viewed at arm-length but I presume you didn't mean
that.
