Unless there's some control I've missed, the 1160 won't do microweave on
any setting but 360 dpi, and I don't recall "super microweave" at any
speed.

This material wasn't scanned, it was purely made in photoshop -- a
fabricated 13 step test strip: 13 flat rectangles of graduated density.
The effect was faint very straight lines about 1/64th inch apart running
the length of the test strip (vertically) but in the print only visible
(faintly) in the highlights. So far seen only in the test strip print. I
thought it might be an artifact of the flat planes, which I think the
printer resents. Or anyway has trouble with.

Actually it was awful. I'd picked a difficult image,faces were very
spotty & the curve smoothed them wonderfully. Except at 360 dpi looked
like measles again.

Hmmm, that's not clear -- I have to choose one or the other. Both options
are available on most settings.

The b---ards never let you be. As I recall, I had more printing options
in Photoshop 4. This is 7. I've considered going back to 4 for these
negatives, but someone told me you shouldn't run both on same computer.
Is that true, or another urban myth?
