Backlit Polyester (FR B1) — Lightboxes

Backlit Polyester (FR B1) — Lightboxes — made to your size in a choice of 2 fabrics, from 200gsm to 260gsm.

This product is offered across more than one fabric because the right answer depends on where the panel is going and how long it needs to last. The table below sets every option side by side on the specifications that actually decide the choice — weight, opacity, finish and weather behaviour — so you can compare them directly rather than opening a page for each one.

About this format

A lightbox panel is a graphic and a light fitting working together. The fabric has to diffuse evenly across the whole face, and the print density has to be set for transmitted rather than reflected light — which is why an ordinary graphic put into a lightbox looks washed out.

Best for

• Backlit lightbox displays
• SEG illuminated panels
• Retail window lightboxes
• Trade-show light walls
• Point-of-sale illuminated headers

Fabric options compared

Which fabric should you choose?

• 200gsm FR Backlit — Built to be lit from behind — a translucent cloth that spreads light evenly instead of showing the lamps.
• 260gsm FR Backlit — Built to be lit from behind — a translucent cloth that spreads light evenly instead of showing the lamps.

Key advantages

• One product, 2 fabric specifications — compare and choose without leaving the page
• Even light diffusion across the panel with no visible hotspots over the light bars
• Print density calibrated for transmitted light, so colour holds up when the box is switched on
• Reads well both lit and unlit, which matters for daytime and after-hours display
• Silicone edge finishing pulls it drum-tight into standard lightbox extrusions

How ordering works

• Send your artwork — Upload print-ready artwork at any stage — we check scale, resolution and bleed before anything goes to press and come back to you if something needs adjusting.
• Made to your size — Every panel is cut and finished to your dimensions. Tell us the finished size you need and how it is being fixed, and we will allow for hems and fixings correctly.
• Printed by dye-sublimation — Colour is transferred into the polyester fibre under heat, so the image becomes part of the cloth rather than a layer sitting on top of it.
• Finished and shipped — Hems, eyelets, pole pockets, silicone edge and other finishing are applied before your order is folded, boxed and dispatched worldwide.

Technical detail

Printing for transmitted light. A backlit graphic is read with light passing through it rather than bouncing off it, so ink density is set higher and the cloth is engineered to diffuse evenly across the face. That is why a standard opaque fabric placed in a lightbox looks washed out, and why backlit stock reads correctly both switched on and switched off.

What to expect from service life. Indoors and out of direct sun, printed polyester holds its appearance for five years or more. Outdoors, published ranges for dye-sublimated polyester run from roughly six to twenty-four months depending on how exposed the position is, with the shorter end applying in high-ultraviolet regions such as the Southwest, Florida and the Gulf Coast, and in coastal or high-wind locations. Sheltered and north-facing installations reach the longer end. Coated and tarpaulin-grade constructions extend beyond that band because the coating carries the UV load.

Best suited to

Illuminated display — lightboxes, SEG light walls, retail window boxes and point-of-sale illuminated headers.

For conventional front-lit display, our tension knit and blockout ranges give denser reflected colour.
