A printing press is a device that transfers ink to a surface (such as type or printing plates) which is then pressed against paper (or fabric or other substrate) transferring the image onto the paper. Johannes Gutenberg is credited with the invention of the printing press that revolutionized the dissemination of information and the mass production of books, starting with Gutenberg's printing of the Bible. The first printing presses were hand-operated followed by steam-operated then today's printing presses that usually run on electricity.
Printing presses come in all sizes and styles for different printing methods and volumes. While some can sit in the corner of a room, others can fill a room or an entire building.
Web and Sheet-fed Printing PressesIn terms of desktop publishing and graphic design, the web press and, most commonly, the sheet-fed press are used for commercial printing of desktop publishing projects.
In brief, a web press prints on continuous rolls of paper. A web printing press is typically used for very high volume printing such as for magazines and newspapers. Printing presses for flexographic printing, often used for packaging, are usually web presses. A sheet-fed press prints on individual sheets of paper. Brochures, business cards, fliers, pamphlets, and booklets are typically printed on these sheet-fed presses, most commonly using offset lithography.
Printing With a Printing PressAlthough some individuals may have small printing presses, such as a letterpress, for personal use, most printing presses are found at quick print shops and commercial printers and service bureaus.

Preparing Digital Files for the Printing PressUnlike printing to your desktop printer, where you often just click the print button from within your software, desktop publishing files require some more specific and sometimes exacting preparation before being ready for printing on a printing press. Generally, the digital files sent to your commercial printing service or quick print shop will be used to produce printing plates for use on the printing press.
- Sending Files for Commercial Printing covers file types, fonts, and images.
- Use a Preflight Checklist to make sure your files will render properly.
Printing Without a Printing PressDigital printing (including with desktop printers) uses dye sublimation, inkjet, solid ink, thermal wax, and laser technologies. While the inner workings of a printer and the process of getting ink (or toner) onto paper bears a resemblance to a printing press, it uses different processes.
