Not all printers do large format printing. It requires special equipment and special expertise. This particular kind of banner is an inkjet printed product created on either a roll-fed or flatbed inkjet press. After the commercial printing process, the flat sheet of vinyl has to be hemmed for edge protection. Often the printer will punch holes around the perimeter of the banner and then strengthen these holes with metal grommets, so the banner can be suspended from the wall with ropes.
In the case of this banner, though, presumably the top and bottom would need to be folded over and sewn to create a “tunnel” through which the top and bottom metal pipes of the banner stand would go in order to keep the banner flat and vertical, in spite of its weight. (These are called “pole pockets.”) If you can imagine drapes with a curtain rod going through the top under a flap of fabric, you’ll have a good idea of what I’m describing.
A thorough search online came up with an alternative, which involved tying the banner to the stand in numerous places around the perimeter of the image.
I also found very elaborate structures that resembled temporary walls with the inkjet printed fabric stretched over them. I noticed in the ads that these often cost over $1,000, while the simpler banner stands cost about a quarter of this, or a little more.
With this information in hand, plus my client’s description from her email, I sent a request for bid to two vendors.
(Why did I choose brick-and-mortar printers when these banners are also sold online? Because I have worked with these vendors before. They provide support and good ideas, and they back up the quality of their work. Not that online vendors don’t. I just don’t have long-term relationships with any at the moment. If my client balks at the pricing I get, I’ll do more research on the Web and give her some online “web-to-print” alternatives.)
