Trade show, conference and exhibition support services design trade show booths, portable and custom exhibits, and related marketing materials. They also register companies for trade shows, conferences and exhibitions; perform setup and teardown activities; and manage logistics. Trade show, conference and exhibition support services that design trade show booths may use computer-aided design (CAD) software to produce conceptual drawings and scale models. Companies that specialize in the design of custom or portable exhibits can produce displays that are light-weight, durable, inexpensive to ship, and easy to setup. The ability to produce attractive, high-impact, trade show graphics is also an important consideration when selecting trade show, conference and exhibition support services. Many trade show services can produce dimensional and architectural signage, computer-cut vinyl graphics, trade show banners, and large-format printing.
