Quark Publishing System

The Quark Publishing System (commonly known by the acronym QPS) is a collaborative workflow management system first released in 1991 by Quark, Inc.. It allows the creators of large publications to manage the process by which the publications are created, and also track the flow of created materials through the various phases of creation, editing, review, combination, and printing. It is mostly used by the producers of periodical publications like magazines, newspapers and catalog but also occasionally used for producing complicated one-off publications like books and advertising materials.
