So far I have observed no effect. But between Stephen and Roy, an
authoritative answer ought to be available; the control appears to be
undocumented in QTRGui help.

Matte vs. Photo ink applies only to black, and then only if both blacks
are housed in the printer. At present, this means the Epson 4000 only.
And QTRGui has a separate control for selecting photo vs. matte black.

Yes, which is what I meant by "curves" (internal to the Epson driver).

Suction is a feature of wide format printers only. Possibly the "Media
Type" setting in QTRGui controls this, but I don't know. Which is why I
asked.

Perhaps you are referring to ICC profiles? The Epson driver certainly
changes ink loading (what I meant by "curves") as a function of media
type no matter what color management scheme is in use. Of course,
certain media settings are synonyms for certain others in some printers.
