Hi Ernst,

Thanks for the detailed information.  It'll take some time to digest 
the information in those links.

You mentioned the dither as a variable, and I've been wondering if 
that is another stake in the piezo heart.  With the semiconductor 
type fabrication, these thermal heads are able to economically have 
an enormous number of nozzles.  Among other things, this may allow 
them to have more advanced dithering that avoids the overloading when 
additional inks are added to the 100% black patch.

Then again, I think there is a lot of advanced chemistry that is 
going into these pigments.  Carbon has the history, but my brother, 
who did his Ph.D. thesis on the vaunted carbon-carbon double bond, 
did not think carbon alone would be the ultimate inkjet black 
pigment.  I think we'll see more neutral, blacker, and possibly even 
more lightfast black pigments in the future.
