A method of transferring sheets from one printing unit to another on a sheetfed press (especially that used in offset lithography) in which a large-diameter transfer cylinder carries the printed sheet from one impression cylinder to the next. The actual size of the transfer cylinder varies according to press design, and may be designed to hold one or more sheets at any one time. The transfer cylinder typically possesses one of a variety of devices or means to avoid marking or smudging wet ink, and may contain a gripper-bowing device. It may also be an air-transport drum. (See also Air-Transport Drum, Chain Transfer, Three-Drum Transfer, and Transfer Cylinder.)
