Digital BW, The Print

I've seen some examples of piezography prints that are just beautiful and 
what I like about them is that they don't look digital.   From what I understand 
(which isn't a lot) it that the not-digitally rendered look occurs because there is 
no dither pattern.  I just saw an example of an "ultrachrome" print on a 2200 at 
a friend's studio and it looked great, but it had a dot pattern that was 
distinctively digital.  I have yet to see a "real world" example of a MIS print next 
to a piezography print.  Is there a way to get the MIS system to communicate 
to the printer in a similar fashion to make distinctively "non-digital" look?  How 
would I find examples of this?  This may be a different question but can you 
export to the Piezography driver with the MIS inks on a 1280? 

I'd appreciate feedback from anyone who has had experience with both 
systems.

Thanks.
