Digital BW, The Print

Has anyone here made digital negatives?  I'm going to try my hand at carbon transfer printing.  See: http://www.alternativephotography.com/articles/art110.html if interested.  Since it's a contact process, I'm going to try making digital negatives, as per Ron Reeder.  See: http://www.ronreeder.com/page8117.html if interested.

Currently, I use an R2400 with MIS K4 inks, although with QTR I do occasionally get banding issues.

Would an Epson 1400 with it's smaller drop size be a better choice?  Anyone have info on the UV blocking abilities of the various inks? So far, I've heard that MIS inks block significantly less UV than Epson's K3 inks.
