I do all of my own printing on Canon large format printers that utilize 16-bit print technology. Paper prints are guaranteed to last more than 90 years when properly displayed behind UV-protective glazing and away from direct sunlight. Canvas prints also have a 90+ year longevity rating, and are easy to care for using a soft damp cloth for occasional dusting.
Prints larger than 11"x17" will be shipped in a heavy duty 3-ply kraft mailing tube, insured for the amount of your purchase. Smaller prints will be shipped flat, sandwiched between heavy duty protective cardboard.
Multiple rolled canvas prints should be unpacked, unrolled, and laid flat as soon as possible after receiving them. They should also be stretched within one month to prevent any small stress cracks from forming in the protective varnish along the edges of the stretching frame.
