UNISIGN · Lightbox material selection
PVC Flex Face Material for Light Boxes
Choose a translucent PVC backlit roll that fits the lightbox, print method and edge system. Then approve the same printed sample with the lights off and on.
UNISIGN supplies unprinted PVC backlit rolls for sign makers, printers and distributors. Use this guide to shortlist a material for your frame and print trial.

Start With the Cabinet Design
| Material route | How it is used | Choose with |
|---|---|---|
| PVC flexible face | A reinforced PVC face held by a matched tension system | The frame, edge method and printed sample |
| SEG textile | Fabric with a silicone edge fitted into a matching frame channel. See LightBox Fabric. | The fabric, print method, cut size and edge/channel fit |
| Translucent adhesive film | Film applied to a suitable supporting sign face | The approved film/substrate combination and adhesion |
A backlit roll and a translucent sticker serve different roles. Confirm whether the job needs a new flexible face, a fabric graphic or film to decorate an existing face.
Balance Brightness and Even Light
| Check | Simple meaning | Look for on the sample |
|---|---|---|
| Transmission | How much light passes through | Brightness and colour in the complete sign |
| Diffusion | How light is spread | Bright spots, stripes and dark edges |
| Blocking | Where light is stopped | Opaque borders or masked areas when the design needs them |
Use backlit material for the lit image area. The material, ink and light source work together. An extra diffuser can hide the LEDs while also reducing the light reaching the viewer. Record LED type, spacing, light colour, cabinet depth and any diffuser.
Approve One Sample in Two Lighting States
Print a test with white space, brand colours, dark areas, fine text and a smooth colour fade. Keep the same sample in the same lightbox for both checks.
1. Lights OFF
- White face and brand colours
- Dark areas and fine text
- Print bands, marks and wrinkles
- Flat edges and aligned joins
2. Lights ON
- Colour and dark-area density
- LED spots, stripes and dark corners
- Visible scrim, pinholes or shadows
- Bright or dark seam lines
For comparison photos, keep camera exposure, white balance and viewing position fixed. Label each image with the model, print mode and lighting state. These are sample-check steps, not measured results for the listed models.
Set the ink for the job
- Use the media profile for the exact printer, ink and material.
- Tell the printer whether the sign must look good both lit and unlit.
- Compare ink settings before the full run; a richer lit image can look darker with the lights off.
- Follow the ink supplier’s drying or curing instructions before finishing.
- Check adhesion and appearance after the planned edge work.
The product pages list solvent, eco-solvent, UV and latex ink families. They do not set one ink limit or curing temperature for every machine. For weight-specific checks, see the 680 GSM backlit banner guide.
Match the Frame, Edges and Seams
- Get the drawingRecord visible size, full cut size and the frame name.
- Match the edgeConfirm the clamp, bead, strip or other attachment method.
- Plan the layoutAllow for margins, trim, edges and any panel joins.
- Fit a trial faceCheck flatness, edges, tension and the lit image.
Follow the frame supplier’s cutting and tensioning instructions. Roll width is not the finished image width. Compare a wider roll with a joined layout, including waste and handling.
If a seam is needed, make a sample with the planned process. Check its strength and its appearance with the lights off and on. Let the cabinet supplier and project team approve the complete face and fixing design.
Use the 3.2 m roll-width guide for the difference between nominal roll width and usable print area.

Lightbox Material Questions
Is every backlit banner a fit for a flex-face frame?
Choose the roll with the frame supplier’s material and edge requirements. A printed and finished trial should confirm the fit, retained tension, seam appearance and lighting result for that combination.
Is there one best light-transmission percentage?
Set the target for the actual cabinet, light source and printed image. If a numeric value is required, ask for the selected model’s measured result, test method and sample conditions. Photo brightness and GSM do not give a transmission percentage.
Should I always use more ink for a lightbox?
Use a tested backlit or day/night profile for the exact printer, ink and material. More ink can help lit colour in some workflows, but can also make the unlit image too dark or change drying and curing needs. Approve both views.
Can PVC replace SEG fabric in the same frame?
Treat them as separate material routes. SEG uses fabric and a matching silicone edge/channel. PVC flex face uses the edge and tension system specified for that face. Confirm a complete approved combination before a change.
Can I make a lightbox face without a seam?
Compare the full cut size with the roll and usable print width. Include all frame and finishing allowances. If a join is needed, approve a joined sample with the lights off and on.
