granted that we are a forum of experimenters, have you checked out any of the vendors that sell B/W ink sets for Epson printers? I used to buy my refill inks from MIS before I found Precision Colors. I remember that MIS had B/W ink sets for four color Epsons that could be purchased with different tones - warm, cold, etc. They might have sets for the six color printers also. Their email address is http://www.inksupply.com/inks.cfm.
