As Kathy said, I don't think you can beat Epson's Ultrabright and Durabright inks for the kind of work you're doing. I've not actually tried the art canvases on my printers. I use the craft fabric for children's books and find the inks wear nicely and are even washable. I figure if a toddler can't ruin it in a year, the ink has to be good. The colors are also nice and bright on the fabric. I've also printed from Painter X using the same printers, but not on the fabric. For Painter X stuff, if I want it printed on art canvas, I send it off to someone else to giclee.

I can second the "thumbs up" view on the R1800 - very good price for what you get, very hard wearing ink, and prints fine on "real canvas" paper :)
