Artwork fabrication
The artwork is added after the structural elements are in place. The method of application depends on the design of the sign. Some advertisements are hand painted directly onto plywood sections that are directly attached to the billboard frame; others use lithographic prints prepared on large vinyl sheets, which are pasted onto the sign face. Usually, hand-painted billboards are used for small campaigns that want to achieve a higher quality look.
Electrical connection
Typically, local electrical contractors are hired to install the power and lighting systems. In many cases, both sides of the sign are used for artwork, so lighting assemblies are required for both sides. In addition, the sign may require special wiring to operate moving parts or other special effects. All wiring must be done in accordance with relevant electrical codes.
