Digital BW, The Print

I'd like to thank everyone for all the advice.  At first, I started 
to reply to each and every response, but I've started to realize that 
I will simply be repeating myself over and over if I reply to 
everyone that's offered their vote on this subject.  Yet, the 
response here is so much more helpful than I've experienced 
elsewhere, I definitely wanted to acknowledge it.  So thanks again to 
all.

Also, one of the posts I just read reminded me of a question I'd 
thought of last evening...

Since the use of colored inks seems to be a source of problems when 
printing B&W with the Ultrachromes, why not just use the Light Black 
to provide the lighter tonalities instead?  I know that 'black only' 
printing results in noticable dots that some find objectionable and 
that the use of colored inks eliminates this, but wouldn't the use of 
the Light Black ink eliminate this also?  In fact, isn't that why the 
Ultrachrome printers have a Light Black cartridge?  So, I'm 
wondering, am I missing something here?  Does the inclusion of 
colored ink somehow produce smoother gradations than simply using the 
lighter tones produced by the Light Black ink?
