Digital BW, The Print

Hello,

I just got my epson 2200 in today, and I wanted to try printing with 
the epson photo black ink in black only.

I set the printer for 2880 dpi, black only, gamma is 1.8.  Anyway, I 
did get a brownish (sepia cast to the print)

Just wondering?  Anyway, the eboni ink I ordered will be in tommorow.

Thanks
Steve Persky
