True, the opposite though, MIS or Piezography inks in Europe, is more 
problematic so OCP is a candidate for Europe.

My goal is not to make nice prints with a BO or Multi BO printer but to 
find the Dmax of a paper for several black pigment inks. That 
information could then represent what a range of quad and color inksets 
could have in Dmax on that paper. It is a 3 picoliter minimum droplet in 
the R200/300 models so already twice the 1430 minimum droplet size but a 
good average droplet size between the 1.5 picoliter of the recent 
desktopmodels and the 3.5-4-6 picoliter droplet of the wide formats.
