Subject: [Digital BW] Re: Eboni-6 inkset - Bases

 

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
