Desktop publishing (also known as DTP) combines a personal computer and page layout software to create publication documents on a computer for either large scale publishing or small scale local economical multifunction peripheral output and distribution. Users create page layouts with text, graphics, photos and other visual elements using software such as QuarkXPress, Adobe InDesign, the free Scribus, Microsoft Publisher, Apple Pages and (to some extent) any graphics software or word processor that combines editable text with images. For small jobs a few copies of a publication might be printed on a local printer. For larger jobs a computer file can be sent to a vendor for high-volume printing.

The term "desktop publishing" is commonly used to describe page layout skills. However, the skills and software are not limited to paper and books. The same skills and software are often used to create graphics for point of sale displays, promotional items, trade show exhibits, retail package designs, and outdoor signs.

History

Desktop publishing began in 1985 with the introduction of PageMaker software from Aldus and the LaserWriter printer from Apple Computer for the Apple Macintosh computer. The ability to create WYSIWYG page layouts on screen and then print pages at crisp 300 dpi resolution was revolutionary for both the typesetting industry as well as the personal computer industry. Newspapers and other print publications made the move to DTP-based programs from older layout systems like ATEX and other Eoach programs in the early 1980s.

The term "desktop publishing" is attributed to Aldus Corporation founder Paul Brainerd, who sought a marketing catch-phrase to describe the small size and relative affordability of this suite of products in contrast to the expensive commercial phototypesetting equipment of the day.

Often considered a primary skill, increased accessibility to more user-friendly DTP software has made DTP a secondary skill to art direction, graphic design, multimedia development, marketing communications, administrative careers and advanced high school literacy in thriving economies. DTP skill levels range from what may be learned in a few hours (e.g. learning how to put clip art in a word processor) to what requires a college education and years of experience (e.g. advertising agency positions.) The discipline of DTP skills range from technical skills such as prepress production and programming to creative skills such as communication design and graphic image development.

By the standards of today, early desktop publishing was a primitive affair. Users of the PageMaker-LaserWriter-Macintosh 512K system endured frequent software crashes, the Mac's tiny 512 x 342 1-bit black and white screen, the inability to control letter spacing, kerning (the addition or removal of space between individual characters in a piece of typeset text to improve its appearance or alter its fit) and other typographic features, and discrepancies between the screen display and printed output. However, for that moment in time, it was received with considerable acclaim.

Behind-the-scenes technologies developed by Adobe Systems set the foundation for professional desktop publishing applications. The LaserWriter and LaserWriter Plus printers included high quality, scalable Adobe fonts built into their ROM memory. The LaserWriter's additional PostScript capability allowed publication designers to proof files on a local printer then print the same file at DTP service bureaus using optical resolution 600+ ppi PostScript-printers such as those from Linotronic. Later, the Macintosh II was released which was much more suitable for desktop publishing because of its larger, color screen.

In 1986, the GEM-based Ventura Publisher was introduced for MS-DOS computers. While PageMaker's pasteboard metaphor closely simulated the process of creating layouts manually, Ventura Publisher automated the layout process through its use of tags/style sheets and automatically generated indices and other body matter. This made it suitable for manuals and other long-format documents. Desktop publishing moved into the home market in 1986 with Professional Page for the Amiga, Publishing Partner for the Atari ST, GST's Timeworks Publisher on the PC and Atari ST, Calamus for the Atari TT030, and even Home Publisher, Newsroom, and GEOPublish for 8-bit computers like the Apple II and Commodore 64.

During these early years, desktop publishing acquired a bad reputation from untrained users who created poorly-organized ransom note effect layouts — criticisms that would be levied again against early web publishers a decade later. However, some were able to realize truly professional results. For example, .info (magazine) became the very first desktop-published, full-color, newsstand magazine in the last quarter of 1986, using a combination of Commodore Amiga computers, Professional Page desktop publishing software, and an Agfagraphics typesetter.
