When you are judging the quality of a scanner (on the monitor), what do
you look for? One of my former teachers told me to pull the curves up
high (on the bright side) on a scan, and look for multi-color
pixelation, horizontal lines, and such. B/c sometimes the noise is
obvious and other times, it might not look so bad to the eye when it
comes into Photoshop, surface-wise, but problems show up when it goes to
print.
Thanks, lavina

We use both criteria, plus openness of the system (i.e. as
non-proprietory as possible). No formal guidelines.
