Lightbox graphics

Identify the frame you actually have

The way a graphic attaches decides what can be printed. Snap frames open at the edges and hold a thin rigid or film insert. Fabric systems use a silicone edge pressed into a channel, so the print must be sewn to a tight tolerance. Older sign boxes may have an acrylic face panel that the graphic is fixed to. Photograph the unit, including a corner opened up if you can, and look for a label. That usually tells us more than a written description, and it avoids a graphic that will not fit.

Measuring so that it fits the first time

Three numbers are easily confused: the outside frame size, the visible window, and the graphic size that sits behind the frame lip. You need all three. Measure in millimetres, at more than one point, because older frames can flex out of square. Keep logos and text inside the visible window with some breathing room. If you have an old graphic, measure that as well, or send us its dimensions. If you have a brand template from head office, share it, since many chains specify these details already.

Film, fabric and the look you want

Printed film gives sharp detail and suits close viewing, so it is a natural fit for menus and product shots. Stretched fabric glows softly, hides light spots well and folds for transport, which is why fabric banners have much in common with exhibition lightboxes. Whichever you choose, remember that colours shift when lit. If your unit has dim or uneven lighting, a new print will not fix that, so check its condition using our backlit displays guide.
