Digital BW, The Print

I have been doing color digital printing for a while now.  I do have experience in the BW 
wet darkroom and I want to dabble in digital BW printing.  I do not want to dedicate my 
Epson 2200 to BW inks but I do have a Epson C64 and I am wondering if I could start with 
this?  I did notice that MIS offers Ultratones for C84 and I believe that the C64 and C84 use 
the same cartridges so is it safe to assume that I can use the MIS inks with my C64.  
Thanks in advance for any help on this matter.
