SEG Tension Fabrics & Replacement Covers or Screens for Lightboxes
Printed Lightbox Covers & Fabric Systems For UK Brand Marketing
Vibrant replacement covers or screens for Lightboxes turn brand graphics into vivid, eye-catching visuals. Lightbox displays use internal LED lighting to illuminate a printed graphic from behind (backlit) or from the front (frontlit), producing a bright, professional look even in well-lit environments.
The graphics are typically printed on fabric with silicone edging (SEG) that clips into a slim aluminium frame. SEG tension panels create a taut, seamless face with no visible fixings. Fabriblock and Jet Display (Frontlit / Opaque) fabrics prevent light from passing through while Lumiweave or Lumiweave Eco (Backlit / Translucent) allows light to pass through the print, creating bright, even illumination.

Our sister Company, Northern Flags specialises in dye-sublimation printed fabrics for free-standing, wall-mounted and ceiling lightboxes, delivering foldable, easy-to-transport graphics for all types of lighboxes.
This combination of high-resolution printed replacement covers or screens for lightboxes and LED lighting makes printed lightboxes especially effective for making brands stand out with indoor displays.

Lumiweave is Perfect for: Retail illuminated displays, reception areas, wall-mounted advertising displays, point-of-sale displays LED lightboxes, menu boards, airport signage, and any application requiring backlit graphics with superior light transmission.
