Digital printing refers to a method of printing a digital-based image directly onto a substrate. This is often referred to as professional printing, where small batches of jobs from desktop publishing and other digital sources are printed using large format and/or high capacity laser or inkjet printers. Digital printing has a higher cost than traditional offset printing methods for each printed object, but can generally be cost-effective by avoiding all the technical steps in between that are required to make the printing plate, thus counteracting the higher price. Digital printing also allows on-demand printing, shortens turnaround times, and even allows modification of the image of each printed copy. The saving in labor and the increase in digital capabilities means that digital printing is reaching a critical point where digital printing can match or replace the ability of offset printing techniques to produce larger print volumes of thousands of prints at low prices.
