Digital BW, The Print

There is an article in Photo Techniques this month on toning monochrome 
prints digitially -- not rocket science, but not something I had 
thought of either.  I tried a slight blue tone on a winter shot I had 
taken recently and really liked it.  The problem comes in trying to 
print the file.  While a print using an R800 captures the blue tone 
nicely, there is a marked loss of quality (versus the same print from a 
1280 using UT2 inks), especially in the midtones.  

Is there a way to get to the same endpoint using Paul Roark's curves 
and the UT2 inks on my 1280?   Or can anyone think of a why to print a 
toned monochrome (now an RGB file) without a dramatic loss of tonal 
separation?

Thanks,

Steve
