I realized in my excitement I didn't really explain what I was doing or my equipment. Sorry about that. I spent so many days searching the internet for people using my specific printer with canvas so I would know it worked before I bought everything I needed but never really found the confirmation so here it is for other people in my shoes. I have an Epson R2400 and I use the roll feed. Some people cut the canvas and use the back feed (where you feed Velvet Fine Art Paper, but I don't see the point). You have to work the canvas a bit to make sure it is loaded properly but you'll know when it is because the printer will grab it. Epson has directions for loading roll paper and canvas on their website if you lost the instructions that came with your printer like I did. I chose to use The Epson PremierArt Water Resistant Canvas, mainly because of price and the fact I could get it in town for the same price as online.
As for color, it is pretty good if not quite as saturated as you see on screen or as what prints on photo paper. The print settings I used were obviously set to roll then Premium Presentation Paper Matte, the color controls were set to 1.8 gamma, epson vivid. I also made sure that borderless was checked and that high speed and edge smoothing were UNchecked. These settings seem to work for me but all printers and monitors are different so it helps if you already have an idea what your printer does and work with it from there.
I suggest having several prints ready to go and just let it print then trim them off. Be very careful not to touch the surface to be printed before or after printing on it. Let it dry at least 48 hours though I'd really suggest 5 days. Helps keep corner cracking to a minimum when you stretch it. After stretching, it will need a protective coat. I picked up a jug of PremierArt Eco Print Shield. Kind of pricey but it protects the image from dings and evil sunlight.
Also, realize the biggest prints you can get are going to be 11 inches wide if you are stretching the image (with the R2400 anyway. I have been looking at bigger printers since starting this). If you want a standard frame size then 11x14 but you could technically print 11 by the length of your roll if you wanted. Very nice for panoramic images. Of course it helps if there are stretcher bars the size of your image so plan ahead. I make sure my image is at least an inch larger on all sides so that I can do a gallery wrap of the image. I like it when the image continues over the side of the stretcher bars.
Hope this helps someone out there. This is the info I wanted to know before trying it but went ahead and jumped in anyway. Luckily things worked though I had one print that didn't feed properly and ended up with the image all squished together. Luckily, it was an image of a stand of trees and it ended up looking good despite what happened. Mistakes are pretty pricey but the results are worth it. It's funny what ends up looking really good on canvas. Not necessarily the same images that look good printed on photo paper.
