Hi Ian
I have a Canon 42" and prints very well on canvas, BUT….
my opinion is that the canvas market is saturated and is tough to do well in if you are only starting now, I tried and failed but could be because it was a side line project, I still advertise it on my site but all I do now with the printer is posters and banners.
Also the size you want will only do small prints, remember that the canvas has to wrap around the back of the frame so your actual face area for an image is small, you will have to have at least 4 inches to wrap it so max image will be 20".
If you are thinking of starting it up think carefully and do a lot of research first, if you think you can do it and will work in your area then go for it.
Hope that helps
cheers
Warren
