I sub out banner orders. With a lot of these companies charging less tan $1 a foot it's just not worth the headache of making them in house.
Right, this is a huge aggravation to me. I can take the same image that goes on a banner, but print it to some vinyl the mount that vinyl to a signboard and be able to charge, say $12 sq. ft. It took the same amount of time, usually less, since there isn't any hemming and grommeting involved. Even way less time if I could direct to print to the board! Banners are a huge money pit now, when other shops are eagerly scrapping away at that market for $1 sq. ft. I say let them do it, I'm going out for brunch, maybe a matinee. And I'm still ahead vs. time I wasted creating the banner in-house. It's all about time management and your hourly labor costs.
Seriously, unless you have at least a 3.2m wide printer, and say a weldmaster dual sided hemming machine, with in-line grommet punch... it's not worth it to be in the banner game. BTW, when you order scrim banner material that wide, you can get the rolls for $100, and full solvent ink is like $40 a liter!
