What are Silicone Edge Graphics (SEG)?

SEG stands for Silicone Edge Graphics. It is a modern display system designed to look "frameless."

  • The Fabric: We print high-density polyester fabric using Dye-Sublimation.
  • The Keder: A thin silicone strip (keder) is sewn directly into the edge of the fabric perimeter.
  • The Frame: The fabric is inserted into a grooved aluminum frame. You simply press the silicone edge into the frame channel.
  • The Result: The fabric is pulled drum-tight, creating a perfectly flat, borderless image that looks like a rigid panel but has the softness and vibrancy of texture.

Types of SEG Displays We Sell

We offer custom fabrication for any space.

1. Backlit Fabric Lightboxes (Illuminated)

This is our most popular high-impact product.

  • Internal LED Lighting: We install powerful LED lights inside LED lightbox display the frame (edge-lit or ladder lights).
  • Backlit Media: We print on specialized "Backlit Fabric" which is designed to diffuse light evenly.
  • The Effect: When the light hits the dye-sublimated ink from behind, the colors explode with vibrancy. It grabs attention instantly in dim environments or busy trade show halls.

2. Non-Lit SEG Frames (Wall Murals)

Perfect for office decor and retail walls where internal lighting isn't needed.

  • Low Profile: These frames can be as thin as 0.5 inches, sitting flush against the wall like a canvas.
  • Acoustic Benefits: The fabric naturally dampens sound, making these excellent for conference rooms and noisy lobbies.

3. Freestanding SEG Stands

Double-sided frames with feet, used as retail dividers or trade show kiosks.

Why Switch to SEG Technology?

Smart NYC businesses are replacing heavy rigid signage with SEG Fabric Lightboxes for specific ROI reasons:

  • Easy Graphic Swaps: Once you install the frame, you never need to replace it. When you launch a new campaign, you just order a new Replacement SEG Graphic. Your staff can swap the fabric in minutes without tools.
  • Glare-Free & Frameless: Unlike glass-covered posters, fabric has no reflection. The "frameless" look maximizes your visible graphic area.
  • Cost-Effective Shipping: A large 8ft x 8ft rigid board is a nightmare to ship. An 8ft x 8ft SEG graphic folds into a small envelope, saving you hundreds in shipping costs.
  • Vibrant Color Depth: Our Dye Sublimation Signage process ensures deep blacks and rich colors that look stunning when backlit.

The Digital City Advantage: Precision & Speed

SEG requires extreme precision. If the fabric is 1/4 inch too big, it wrinkles; too small, and it won't fit. Digital City Printing ensures a perfect fit every time.

  • In-House Sewing Department: We don't outsource. Our skilled team sews the silicone keder on-site, ensuring the tension is calibrated perfectly for your specific frame.
  • Custom Frame Fabrication: We cut aluminum extrusions to custom sizes right here in Midtown Manhattan. Need a specific 43" x 92" lightbox? We build it.
  • Rush Production: We can produce replacement graphics in as little as 24 hours.
  • Installation Services: We offer professional installation for large wall-mounted lightboxes throughout NYC.

Answer:  Yes, we offer dimmable transformers for our lightboxes upon request, allowing you to control the brightness for different environments.

Answer: We can build lightboxes as large as 10ft x 20ft or even larger by seaming the fabric (though we recommend seamless up to 10ft).
