Backlit Lightbox Trade Panel (150gsm FR)

Backlit Lightbox Trade Panel (150gsm FR) — Built to be lit from behind — a translucent cloth that spreads light evenly instead of showing the lamps, specified for trade-show graphics.

Backlit fabric is engineered around light diffusion. The construction is deliberately open and even so that light entering the back emerges across the whole face without hotspots over the LED strips. Print density is calibrated for transmitted rather than reflected light, which is why a backlit graphic printed on standard fabric looks washed out and one printed on this does not.

Trade-show graphics travel. They get packed into a case, flown or driven across the country, assembled by whoever is on the stand that morning, and taken down again three days later — repeatedly, across a season. Fabric earns its place in that cycle because it folds without permanent creasing and pulls flat again under tension.

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

• SEG tension-fabric walls
• Pop-up and curved displays
• Backlit lightbox panels
• Booth headers and hanging signs
• Retractable roll-up banners

Key advantages

• 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
• Lightweight and rollable — ships and stores flat between campaigns

Specifications

Choosing the right specification

Measure your frame system before anything else. SEG extrusions differ between manufacturers, and a graphic cut for the wrong groove will not seat cleanly, so tell us the frame make and model when you order. It is also worth checking your venue's own exhibitor rules early, since they can set requirements on materials and rigging that are easier to design around than to fix on site.

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.

This is the 150gsm version. The same specification is also made as SEG Backlit Light Box Panel — the fabric, print method and finishing are identical across them, so the only decision is which size fits your setup.

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.

Also in this range

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