Digital BW, The Print

Robin,

I would suggest that you see if you can return the cartridge to MIS since
there is no workflow for those inks in that printer. Piezo doesn't support
it either as far as I can tell. If you do want to use quad inks in a 780 I
think that you will be on your own a bit as far as developing a workflow.
You could try the MIS VM ink set and then try modifying some of the RGB
curves used by other printers. Or the original Quads and try the Brandin or
Nevins methods.

In all honesty, I would suggest that you pick one of the printers that is
more widely supported for grayscale inks. Your life will be much simpler.
