Digital BW, The Print

John,

I can't imagine you'd damage your printer by trying the UC yellow.  I run
MIS, UC and Archival inks through all the smaller printers, and they all
seem very similar and compatible.  I would guess the downside is simply that
it won't give you the reds you want due to the Archival magenta still being
there.

I wonder what Epson did when they "retrofitted" the printers for the UC inks
-- besides make money on the process.  The UC inks carry a higher load of
pigs, so the viscosity might be a bit higher.  However, from my
measurements, all these inks are fairly close.  The only higher viscosity
ink I've run into was the magenta.  The MIS 7600 M was a bit too high for
the 1280, thus the "GP" inkset.  It didn't damage the printers as far as I
know.  The yellow is not that likely to have too high a viscosity because it
is the lightest (specific gravity) of the bunch.

I'm not familiar with the 10000, so I don't know what problems you might
have with chips, etc.

Good luck with the experiment.
