I've found printing on canvas to be a lot more forgiving than most other papers. It handles easily, doesn't kink as easily and good canvas materials have an incredibly durable surface that's less susceptible to fingerprints, scratching, etc. I've been working with a 5x7 foot print size exclusively for the past few years and the advantages at this size are particularly important. As for color management, you certainly need to print and coat your profiling target as you would your final prints prior to measuring and generating profiles. If you do so, you won't have any issues with blocked up shadows and the like - that's a color management problem, not a canvas problem. If you are having problems with fingerprints and surface durability you might consider switching to a different canvas. Significant advances have been made in just the last year. Applying an liquid laminate to canvas makes them even more durable.
