I am new to this forum and a newbie with QTR.
I am currently testing QTR for my own usage and it is possible to create a curve for printing with the black only (BO) ink. I have created one for the regular Epson matte ink (MK) with my Epson R3000 and I assume using the photo black PK will be similar. Paul Roark on his website http://www.paulroark.com/BW-Info/ provides a few black only (BO) qtr curves for another Epson printer but it can serve as an exemple.
Being based in Europe I am interested in your attempt to use the carbon inks from farbenwerk.com. Can you please share your experience?
