Digital BW, The Print

I have the 1280 and Ultra Tone (UT) inks running.  Using the standard 1280
driver, the results, including with the warm/carbon curve, are probably the
best prints I've yet seen.

I had some initial clogging, but I suspect it was caused by residual OEM dye
on the parking pad.  And the problem appears to be easy to solve. This
should only be an issue for those who have just used dye in the printer
before installing the UT inks.

MIS has found that the Eboni black ink can react with the OEM dye.  There is
not enough dye in the heads of desktop printers to be a serious problem.
(Large format printers must purge.)  However, I think a problem can come
from the dye that is on the parking pad.  This 1280 (that had just been used
with OEM dye) often took a cleaning cycle to get a clean nozzle check after
even a short sit on the pad.  I've never had any UT clogs like this on
printers that had not previously used dye ink.  So, on the 1280 I cleaned
off the parking pad by flooding it with Windex and wiping it with a paper
towel.  I also wiped the head with a Windex-soaked paper towel.  The
clogging now appears to be gone.  So, for those who have used dye in
printers, I'd recommend cleaning the parking pad with Windex before
installing the UT inks.

I'll have the first (EEM/EAM) curves set ready to ship to MIS and others
today.
