Digital BW, The Print

Paul, I'm missing something....are you saying this inkset will be sold on MIS (say, for my 
2200)? Or is this something we'd have to mix ourselves. Plus, I don't use Create-ICC (tech 
naif), only QTR profiles. But would that be something I'd have to get into in order to use 
Eboni-6?

thank you,
Sarah
