Digital BW, The Print

Charles,


>... 1280 ... UT ink (using the Photo Black) ... lustre paper.
>Adobe RGB... 1440... UT80-N...No Color Adjustment...Photo Paper setting

Those setting are right.  I have not tried luster paper in the 1280 with the
UT80-N curve, but it should be close, based at least on my experience with
the 1160 and UT inks.

>The print was bizarre - pure toner in some areas, pure "yellow"
>(warm grey) ink in other areas, highly posterized. ...

Assuming the image was converted to RGB before printing, the next thing I'd
check is the ink positions.  Print the Purge6 pattern and be sure the toners
are in the magenta and light magenta positions.  The yellow is the lightest
gray, then the light cyan, with the cyan the darkest gray.
