Definitions for "Master Page"
A feature found within page layout software that allows the user to create quick consistent page layouts. Any printing element or non-printing guide will appear on all pages of the document.

It may contain headers, footers, page numbers, ruling lines, margin features, graphic elements, layout guides, and any repeating text.
