Digital BW, The Print

Speaking of dot size for the older machines, I've never found an official
rating for the 7500 and its siblings.  Inkjetart.com has a couple of
statements regarding this generation of printer:

"[T]he 7500 is a static 8 picoliter droplet size (according to one Epson rep
we spoke to at the PMA show)."
http://www.inkjetart.com/news/archive/IJN_02-20-01.html

On the other hand they also have an old comparison that mentions a different
measurement: "The Epson Pro 5000 printer and the new Epson Pro 9000
wide-format printer are a different "breed" ... These two printers have
Epson's Micro Piezo Dual Density Droplet (DX3) Print Technology which offers
precise 11-nanogram dot size for remarkably small, clean, sharp dot
placement, and achieving remarkable photographic clarity."
http://www.inkjetart.com/news/dot_comp.html

I'm not sure how the 2 different measures compare.  I'd guess that the
specific gravity of the ink should be used to equate the 2.  If so, that
would put the ink at about 1.38.  I've never measured it precisely, but I
was of the impression it's about 1.2.

The name of the head technology suggests it might support a variable dot,
but I've never heard that any rip actually accomplishes this.
