Transform your LED lightboxes with high-quality Tension Fabric Replacement Graphics & Covers for various types of LED Lightboxes.

Lightbox graphics are quick and easy to install. A silicone strip is sewn into the edge of the tension graphic and slots neatly into the channel of the lightbox frame. Once fitted it forms a tensioned fabric surface with a seamless, edge-to-edge finish.

Northern Flags specialises in dye-sublimation printed tension fabrics (SEG) for free-standing, wall-mounted and ceiling lightboxes. As specialist wide-format printers we deliver premium tension fabric graphics with superior light transmission, foldable, easy to handle, transport-friendly and perfect for retail displays, exhibitions and interior decor lighting across the UK.

SEG Tension Fabric Graphics for Lightboxes

What Are Tension Fabric Graphics for Lightboxes?

Tension fabric graphics are specially printed fabric panels designed to fit perfectly into LED lightbox frames. These graphics feature silicone edges (SEG) that slide smoothly into the channels of lightbox frames, creating a taut, professional finish without visible fixings.

What We Sell | SEG Tension Fabric Printing

We supply printed tension fabric graphics and replacement covers for LED lightboxes. Choose from the following main fabric types:

  • Jet Display (Backlit / Translucent): Allows light to pass through the print for bright, even illumination. Lit from behind (backlit) to produce vivid colour and uniform glow.
  • Fabric Bloc (Front-lit / Opaque): Blocks light from passing through. Ideal for front-lit displays or when a matte, solid appearance is required.

Compatible Lightbox Types For SEG Tension Fabric Graphics

Tension fabric lightboxes are versatile visual powerhouses designed to captivate in any environment. Whether illuminating high-traffic retail zones, energising exhibition stands, or enhancing interior spaces, they deliver standout visibility. Use free-standing units for 360° brand presence, wall-mounted options to elevate ambience, or ceiling-mounted displays to command attention from above.

  • Free-standing lightbox displays for retail and exhibitions
  • Wall-mounted lightbox graphics for interior decor and retail environments
  • Ceiling lightbox systems for dramatic overhead displays
  • Backlit promotional displays for shopping centres and showrooms

Installation Tips

  1. Inspect the frame channel for damage or debris before fitting.
  2. Confirm orientation marks (TOP / FRONT) on the graphic.
  3. Start at a top corner, insert the silicone strip and work along one side, then opposite tension gradually.
  4. For large frames, use two installers to avoid skewing.
  5. If the silicon strip won’t tuck, check the diameter vs channel and wrapping. You can contact us for rework guidance.
