Has an R800 owner actually tested this?  It sure doesn't work that way with
MIS glop.

The 2 component polyurethanes can be very strong coatings.  I wonder in the
inkjet setting if the 2 jets of it would overlap properly for mixing.  Even
if they overlap sufficiently, is there enough mixing on the paper to avoid
having the separate components only partially mixed and cured?  I'd also
want to be sure there was no setting up of the PUR on the head or parking
pad.  I'm not sure if the UV cure types stay totally liquid in the absence
of strong UV or if they would slowly cure on the head and parking pad.

With those caveats, however, I think the 2 component approach has great
promise for coatings and inks themselves.
