Quark Software Inc. (founded 1981 in
Denver, Colorado) is a privately owned software company which specializes in omni-channel enterprise publishing software for automating the production of high-value customer communications. The company's original goal was to "create software that would be the platform for publishing", just as quarks are the basis for all matter. The company is best known for its desktop page layout and design software,
QuarkXPress, although this has now become secondary to its enterprise software solutions.
