Black duvetyne and commando cloth are common stage-masking materials. Compare weight, opacity, nap, flame-treatment documentation and rigging load for the exact product; use a physical light test when a source will sit behind the panel.
Why duvetyne reads black on camera
Duvetyne is a cotton twill brushed to raise a short, dense nap. That nap scatters incident light in every direction instead of reflecting it back, so the fabric reads as a true hole in the frame. Plain black cloth picks up a sheen along any curve and photographs dark grey; duvetyne does not.
Choosing the weight
| 12oz duvetyne | 16oz commando cloth | |
|---|---|---|
| Opacity | Lighter; verify with the exact light setup | Heavier; usually selected for greater light control |
| Light behind the panel | Physical test recommended | Physical test still recommended |
| Weight to rig | Easier to carry and hang | Heavier; needs more support |
| Best for | Touring, trade shows, frequent strikes | Permanent masking, stage legs, blackout |
Where each goes
- 16oz — stage legs and borders, backstage blackout, permanent studio masking, cyc surrounds, any panel with a source on the far side.
- 12oz — touring sets struck nightly, trade-show booths, location work where truck weight matters, flags and floppies lit from the front.
If anything is lit behind the panel, test the exact cloth under the intended distance and exposure. Weight is useful guidance, but opacity also depends on construction and lighting.
Practical notes
- The nap has a direction — hang panels consistently or they read at different densities.
- Check fiber and care instructions before allowing for shrinkage.
- For complete light control, the material also needs adequate overlap at every joint.
- Do not assume FR or NFPA 701 compliance. Require documentation for the exact material and treatment.
