Digital BW, The Print

Hi,

I've been reading the forum messages for some time and have learned a lot.
On the other hand, I still have just one printer and the standard color ink
set.

I am attempting to print using duotones and quadtones.  I use digital
cameras and Photoshop6 and a Canon S800 printer.  I profile my monitor and
my printer.

I am a little confused about the proper Photoshop color settings.  In
particular, what should the setting be for the "Gray" working space?  Any
other tips about duotones and Photoshop settings would also be appreciated.

Thanks for your help and the interesting forum.
