Desktop publishing

Desktop publishing (also known as DTP) is the creation of documents using page layout software on a personal computer.

The term has been used for publishing at all levels, from small-circulation documents such as local newsletters to books, magazines and newspapers. However the term implies a more professional-looking end result, with a more complex layout, than word processing, and so when introduced in the 1980s was often used in connection with homes and small organisations who could not previously produce publication-quality documents themselves.

 History 
Desktop publishing began in 1985 with the introduction of MacPublisher, the first WYSIWYG layout program, which ran on the original 128K Macintosh computer. The DTP market exploded in 1985 with the introduction in January of the Apple LaserWriter printer, and later in July with the introduction of PageMaker software from Aldus which rapidly became the DTP industry standard software.

Before the advent of desktop publishing, the only option available to most persons for producing typed (as opposed to handwritten) documents was a typewriter, which offered only a handful of typefaces (usually fixed-width) and one or two font sizes.  Indeed, one popular desktop publishing book was actually titled The Mac is not a typewriter.Robin Williams, The Mac is not a typewriter: A style manual for creating professional-level type on your Macintosh (Berkeley: Peachpit Press, 1990), 11. The ability to create WYSIWYG page layouts on screen and then print pages containing text and graphical elements at crisp 300 dpi resolution was revolutionary for both the typesetting industry and the personal computer industry. Newspapers and other print publications made the move to DTP-based programs from older layout systems in the 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 software in contrast to the expensive commercial phototypesetting equipment of the day.

Behind-the-scenes technologies developed by Adobe Systems set the foundation for professional desktop publishing applications. Although Macintosh-based systems would continue to dominate the market, in 1986, the GEM-based Ventura Publisher was introduced for MS-DOS computers. While PageMaker's pasteboard metaphor closely simulated creating layouts manually, Ventura Publisher automated layout through its use of style sheets. This software automatically generated indices and other body matter. This made it suitable for manuals and other long-format documents.

During its early years, desktop publishing acquired a bad reputation as a result of untrained users who created poorly-organized layouts — similar criticism would be levied again against early Web publishers a decade later. However, some were able to realize truly professional results.

 Terminology 
There are two types of pages in desktop publishing, electronic pages and virtual paper pages to be printed on paper. All computerized documents are technically electronic, and are limited in size only by computer memory or computer data storage space.

Virtual paper pages will ultimately be printed, and therefore require paper parameters that coincide with international standard physical paper sizes such as "A4," "letter," etc., if not custom sizes for trimming. Some desktop publishing programs allow custom sizes designated for large format printing used in posters, billboards and trade show displays. A virtual page for printing has a predesignated size of virtual printing material and can be viewed on a monitor in WYSIWYG format. Each page for printing has trim sizes (edge of paper) and a printable area if bleed printing is not possible as is the case with most desktop printers.

A web page is an example of an electronic page that is not constrained by virtual paper parameters. Most electronic pages may be dynamically re-sized, causing either the content to scale in size with the page or causing the content to re-flow.

Master pages are templates used to automatically copy or link elements and graphic design styles to some or all the pages of a multipage document. Linked elements can be modified without having to change each instance of an element on pages that use the same element. Master pages can also be used to apply graphic design styles to automatic page numbering.

Page layout is how the elements are laid on the page orderly, aesthetically, and precisely. Main types of components to be laid out on a page include text, linked images that can only be modified as an external source, and embedded images that may be modified with the layout application software. Some embedded images are rendered in the application software, while others can be placed from an external source image file. Text may be keyed into the layout, placed, or (with database publishing applications) linked to an external source of text which allows multiple editors to develop a document at the same time.

Graphic design styles such as color, transparency, and filters, may also be applied to layout elements. Typography styles may be applied to text automatically with style sheets. Some layout programs include style sheets for images in addition to text. Graphic styles for images may be border shapes, colors, transparency, filters, and a parameter designating the way text flows around the object called "wraparound" or "runaround."

 Comparisons 
 With word processing 
While desktop publishing software still provides extensive features necessary for print publishing, modern word processors now have publishing capabilities beyond those of many older DTP applications, blurring the line between word processing and desktop publishing.

In the early days of graphical user interfaces, DTP software was in a class of its own when compared to the fairly spartan word processing applications of the time.  Programs such as WordPerfect and WordStar were still mainly text-based and offered little in the way of page layout, other than perhaps margins and line spacing.  On the other hand, word processing software was necessary for features like indexing and spell checking, features that are common in many applications today.

As computers and operating systems have become more powerful, vendors have sought to provide users with a single application platform that can meet all needs.

 With other electronic layout software 
The key difference between electronic typesetting software and DTP software is that DTP software is generally interactive and WYSIWYG in design, while other electronic typesetting software  requires the user to enter the processing program's markup language without immediate visualization of the finished product. 
This kind of workflow is less user-friendly than WYSIWYG, but more suitable for conference proceedings and scholarly articles as well as corporate newsletters or other applications where consistent, automated layout is important.

One of the early and comprehensive reference books on the art of Desktop Publishing is Desktop Publishing For Everyone by K.S.V. Menon.  This publication deals with virtually every facet of publishing  and nearly all tools available as at the time of the publishing of this book in the year 2000. It is currently out of print.

There is some overlap between desktop publishing and what is known as Hypermedia publishing (i.e. Web design, Kiosk, CD-ROM).  Many graphical HTML editors such as Microsoft FrontPage and Adobe Dreamweaver use a layout engine similar to a DTP program. However, some Web designers still prefer to write HTML without the assistance of a WYSIWYG editor, for greater control and because these editors often result in code bloat.Roughly, a heavy load of code often makes computers slower to react in real time, and printing systems slower to print drafts. 'Higher level' software is easier to learn and use, but usually results in less efficient coding.
