yes, i realize that quadtoning in this way is only 'pseudo quadtoning'. the purpose is not to 
get neutral tones, but to simulate the effect, eg, of selenium toning.

i've experimented with most of these.

original color space is adobe RGB
printer color space is epson's 1440 dpi profile for enhanced matte
relative colorimetric (tried others too)
blackpoint compensation on (and tried off)

in the driver, under print settings:
advanced settings, 1440dpi (tried 2880 too), not high speed, enhanced matte paper
under color settings:
no color management

i've also tried advice from luminous landscape -- color controls set to photorealistic to get 
better shadow details.

none of this seems to help.

i should say that this effect is quite subtle: its only noticeable on some prints, and only in 
certain areas.
