Projects and layouts
QuarkXPress files are referred to as projects, and each project contains one or more layouts. Every layout is stored within a project, and every project contains at least one layout. Each layout can contain as many as 2,000 pages, and can be as large as 48″ x 48″ in size (or 24″ x 48″ for a two-page spread). A project can contain an unlimited number of layouts.
Because multiple layouts can be stored in a single file, you can easily share content between different versions of a document — for example, a letter with identical text in US letter and A4 layout sizes.
A QuarkXPress project can contain three types of layouts: Print, Web, and Interactive. You can use one project to create content for various media — such as print, PDF, SWF, and HTML.
