Digital BW, The Print

applied Paul Roark's UT2-EEM different curves to adobe RGB 98
workspace print with predominate sepia (or brown) tone.  Coolest I can
get is light, light cream on a white  backdrop image.  Can't attain
any silver or even blue tones.  I tried not using curves, but changing
color sliders for CMY too, same result.  

Black is eboni, standard T009 UT2 inkset, cleaned heads, printed about
20 images so far.  After applying curves, printing with all color
settings off, same adobe 98 rgb workspace. Tried different paper
settings (matte heavyweight, and others), even printed on Canon Photo
Paper Pro just to see...same tone.

Seems it is the inkset, not the paper or settings?  

Thanks in advance...
