Digital BW, The Print

The basic, low-level commands to the 4000 do not allow you to use
both matte K and photo K on the same page.  It has nothing to do with
any of the RIPS.  All drivers or RIPS treat the printer as a 7 ink printer
while printing a page.  The selection of which black is to be used is
determined in the initial setup for a page -- once the black is selected
only that black ink can be used for the entire page.   This is not something
that can be gotten around unless Epson changes their firmware in a way
that would be incompatible with the existing interface -- so it's unlikely.

BTW, this is in contrast to the R800 which allows all 8 inks to be used on a page.
