I found this description of durabright ink. It seems to be a variant
of pigment based inks.
http://www.epson.co.jp/e/technology/duratech.pdfThe question is if the print head is really any differet for pigment
based inks. The cleaning system and regiment is probably different.
But the head could be identical.
When someone takes one apart, take a picture of the holes in the head
or put it under a microscope next to a penny... Then we can see the
hole size relative to Lincoln's nostrils.
