Digital BW, The Print

Hi,

I print with the piezo selenium ink set.  I have set up a custom dot 
gain curve so that my output very closely matches what I see on my 
monitor in terms of density.  However, I'd like to be able to post 
digital versions of my work to the web that replicate the selenium 
tone of the final output.

I've tried scanning the final print on a flatbed but I'm really not 
happy with the results.  

Has anyone out there developed photoshop curves or some other method 
to slightly tweak the RGB values of a B+W image so that it will 
appear on screen with the subtle selenium tones of the printed 
output?  Thanks,
