Most people can't say "advertising literature" with a straight face. The people at Penn Lithographics can because they print the stuff. The company produces full-color, press-finished advertising literature and other marketing materials. Products include posters, postcards, calendars, mini-catalogs, brochures, CD holders, and point-of-purchase merchandise. It also provides digital pre-press, binding, and fulfillment services, which include custom assembly and mailing. To save a trip to the shop, customers can send their printing projects to Penn Lithographics through its Web site. The family-owned company was founded in 1934 and serves clients in the western US.
