Fabrics

Fabrics are most commonly used in banners to provide a roll-up solution for temporary signage needs. Size is practically unlimited, and for very large applications special material can be used which is porous to allow the wind to pass through it.

In a similar vein, rigid and semi-rigid porous materials are available which can be printed with a design on one side and appear opaque, yet can be seen through from the other side. Such materials can often be seen on the back of buses to provide a surface to apply the advertisement to while still allowing the driver and passengers to see out of the windows on which the material is applied.
