For RIP developers already supporting n-color ink models, this will
merely be one more implimentation; less troublesome than the 2200,
frankly, since it has enough on-board memory to hold its own
microweave dithering algorithms, so they won't have to be produced
by the RIP and sent over a piece at a time.
According to the programming manual (which I only just found on the
web site), the R800 doesn't support printer weave ("microweave"), so
it's necessary to use softweave. In the event, this shouldn't be much
of an issue, since people who write RIP's already have to support
softweave for every other printer.
For RGB driver
profiling, the extra inks will be invisible, though not in exactly
the same way that light component inks are. Even the possibility of
extra gamut clipping is remote with RGB, since it has peaks at Red
and Blue... CMYK profiles may well miss some of the advantages of
the Red and Blue gamut improvements with some profiling and RIPping
software, however.
I'm trying to work out what to do with all of this in Gimp-Print
(although I first need to get my hands on one of these printers).
This is going to be a really interesting printer to support, that's
for certain.
