Is printing your concern or placement. I would say both:
Printing: At 5 feet and on a flex you better have a really nice fixture to keep everything in check. You'll probably have to hand screen it unless your going to get a dedicated custom continuous printer, the largest off the shelf automated one I’ve seen can only do 36". If your only working on the two ends of the flex, like a flex to replace a cable, you might be able to either bend the middle out of the way making it shorter or do one end and then the other.
Placement is easier put one end it a pass through style machine place the left 24-36" rotate it put the other side in fist and place the right 24-36". If you have a table style (MYdata) hopefully you can either put it at an angle and make pray it fits or bend it where nothing is happening.
When I say bend I don’t mean form but just temporarily contour the flex to fit.
