    摘要: The invention is a simple, inexpensive, wash-free integrated cover for a printing transfer cylinder (preferably, but not necessarily, in a Komori press), comprising a flexible jacket covering permanently attached to a cylinder base cover. The invention provides advantages over T-Y paper and non-tack film in that dampening solution, washing, and cleaning causes failure in both over time, whereas dampening solution is beneficial to the present invention as such is retained in the flexible jacket cover and helps to prevent ink buildup and marking. The flexible jacket covering is moveable relative to the cylinder base cover, thereby further reducing ink buildup and marking. The integrated cover is disposable, which reduces periodic maintenance and cleaning of the transfer cylinder coverings and provides for fresh, clean substrate support surfaces upon each new installation. The flexible jacket covering and cylinder base cover are integrated into a single, convenient unit, thereby speeding and simplifying installation.
