Fabric scrims are used often in visual productions for the interesting effects they create.
When light is stronger on the (audience) observer's side of a mesh fabric, visibility is poor through the net. In fact as shown in the videos below, the user is actually projecting onto the mesh.When the scrim mesh is back lit and light is stronger on the opposite side of the net. Images behind are illuminated. The key is light differential or comparative intensity of front vs back lighting.
Black Theatre Scrims
While white is most commonly used, black has its own visual effect. This is an example of a techniques popular for decorating Halloween homes. The resolution on the black no-see-um theatre scrim for these 7ft tall images is far better than the camera is able to pick up in these photos. The advantage of black is that it is nearly invisible and projections have an eerie holographic effect. Flip on the back lights cut the projector and it is crystal clear. Black Shade improves resolution, but is denser.
Fabricated Theatre Scrims
We custom fabricate any size adding a sturdy perimeter webbing with fasteners like Velcro®, Grommets, Marine Snaps, or even rig it for our overhead tracking. We are VERY good at rigging ideas and are happy to help. All fabrics are pulled from 10ft(wide) bolts and our most popular, Shark's tooth scrim, is pulled from a jumbo 12ft(wide) bolt. Often, clients need very large scrims. To make a 96ft(wide) x 30ft(tall), we would rotate the panels and vertically seam them in 8 panels that are 30ft(tall) x 12ft(wide) using a serge stitch less than ¼ inch wide to be as unnoticable as possible yet very strong.

Comparison of Theater Scrim Colors / Mesh
Imagine you are in the audience at a theater looking at the scrim. The audience side of the scrim is unlit and the lighting behind the theater scrim is bright. You are viewing either a painted or projected image on the theatre scrim . Each mesh/color will have a different resolution of the image on the scim and a different visibility through the scrim to see what is behind. Sometimes you just need white or just need black, but we want to characterize the effects. The photos to the right (Black Shade) are for a different application but gives you a feel for density and transparency with different lighting.
White Shade: The densest, most opaque material and will have the best image resolution for painting and projecting, but poor transparency of back stage objects.
White Sharks Tooth: The most commonly used theater scrim material. Less dense, good image resolution, and very good ethereal transparency of back stage objects. Black Shade: Is a dense Adam's family material. It is dense for painting, projects fairly well and will have transparency similar to White Shark's Tooth. Black No-See-um: Think black window sheer. Bad for painting, images are ghostly when entire theater and backstage are dark. Crystal clear when back lights go on.
