RiXax, We do a steady amount of these and have for years. You can use any large format printer capable of sewing pole pockets. We get our ratchet straps from Billboard Solutions. We use EMT conduit for poles instead of PVC. PVC tends to bow with pressure and heat over time, or outright crack if installed cold. Circle Graphics is the largest printer in North America and does a ton for Lamar Outdoor. Their standard pocket is 3", so a 12'x24' fave size will finish at 13'x25'. I've attached a few pictures. . The ink will start fading about two years in, but under normal conditions is legible for 4-5 years. The vinyl itself will last for years. The 12'x40' that I've shown the backside of and the A-Frame (Flea Market - Art & Frame Outlet) doesn't have any plywood on it, just 2"x 6" stringers After hurricane Katrina there was an ad in a trade journal showing a pic of the structure with a flex and after with the flex destroyed "Before Katrina, this was the largest off premise outdoor advertising structure in the state of Louisiana, after Katrina, it still is". Impressed me. We started building them with a 2 by frame and quit using plywood. Not a single failure yet.
