Dye Sub instead of UV would be my recommendation first of all. The biggest question is whether you have the capital and the available room for the entire workflow. Direct Disperse Dye Sub like a Telios machine will save you time/footprint area because the output is already heat set instead of having to run it through a separate calender or heat press (rotary is my choice). The downside of that is that those machines are much much more expensive than a printer and heat press separately, and many of them are not designed for the heavier knit fabrics that are used for tension fabric displays. Many are designed to be "Flag Printers" because they run very light flag fabric through them. When I was looking at them last year we were looking at a much more expensive machine that could print/calender the heavier knit and stretch fabrics like you're talking about.
Unless you are doing very long runs, consistently, I can't see that an all in one machine makes sense. Just the amount of fabric it takes to web up a machine like that is significant. And if you're doing small projects, it may be best to print to paper then transfer it to fabric using a rotary heat press.
The other thing to consider is that you will need to add sewing capabilities to your workflow, along with space and labor to do it. Sewing this type of product isn't as simple as hiring someone that is good at sewing banners. For SEG only with square frames, it's not so bad but there is a definite learning curve. Sewing pillowcase graphics for stretching over tube frames is an entirely different animal. In either case, there are considerations like material stretch and fit and finish around curved areas. The table space needed is also significant.
Our setup was a 102" Dye Sublimation (Direct Disperse) printer that we would print, then sublimate using a 10-meter rotary calendared heat press. Once sublimated, we would trim it and sew the silicone edge to it on a 5' x 30' table. Many of the graphics we did were for huge backwall graphics that were 8' tall by 20-40 wide. We had a Juki industrial sewing machine and trimmed everything by hand with a heat knife.
