Large format printing” (also often called “wide format printing”) refers to printing on materials that are much bigger than what a standard office printer can handle. It usually requires specialized printers that can output on large sheets or rolls (often from 18 to 100 inches wide or more).

Because of its scale, large format printing needs high-quality inks, proper color management, and durable substrates to ensure crisp images and longevity.
