In computers, a character, set of characters, or code attached to a set of data that contains information about that data, such as its identification, and any formatting information pertaining to that data set.
In desktop publishing, a code attached to a specific piece of text that provides instructions for its formatting. Tags applied to text include its font, point size, leading, the paragraph formatting (i.e., ragged or justified), and any other text attribute. Tags can be applied and manipulated within a specific program (such as QuarkXPress) as a shortcut for formatting blocks of text, or added to straight ASCII text composed in another application for input to a page makeup program. For example, tags used by QuarkXPress can be applied to generic text created in FileMaker and then imported into QuarkXPress, eliminating the need to format each aspect of the text file individually, which saves time when creating large Quark documents from FileMaker files, such as an encyclopedia of 10,000 graphic arts terms.
In papermaking, the term tag also refers to a paper grade characterized by high thickness, strength, density, tear resistance and water resistance, used in many heavy-duty applications such as tags, folders, and covers. The surface of tag stock allows printing, writing, stamping, and folding. It is manufactured from any of the various pulping methods—sulfite, sulfate or kraft, and mechanical. Tag papers also undergo calendering to produce a smooth, hard surface. Coated tag stock possesses enhanced printability, and is used for some printing applications. Tag is also manufactured in a variety of colrs, primarily white and manila.
