For high-volume runs, web printing is an economical way to go. It is an offset process but rather than printing on single cut sheets of paper, web printing uses mounted rolls of paper in order for a continuous stream of paper to run through the press. Once printed, it is trimmed into sheets and/or bound at the other end.
Web offset printing is used for high-volume publications such as catalogs and brochures. Some web presses transfer text and images to only one side of the paper at a time, while others can print on both sides simultaneously.
