Digital BW, The Print

QTR can use any inks you want to use.  For the UC inks the following 
generally applies.  Most of the warm (carbon) profiles use just K and 
LK.  Neutral and cool profiles will add LC and LM to cool or neutralize 
the warm tone of the LK and, more recently also C and M to 
cool/neutralize the warm Epson UC K inks (PK and MK).  Sepia adds LM 
and Y, in the proportions desired so that when mixed with LK a sepia 
tone is obtained.  A "cool Selenium" tone is generated by adding 
slightly more LM relative to LC when making a neutral or cool tone 
profile.
