Printing press.

摘要

A method and apparatus for the automatic production of business forms, wallpaper, newspapers or the like from a web of continuous printing material (W) comprises a printing station (12) including an endless movable printing device such as a rotating cylinder (40). An image is projected to a surface of the device. The image is transferred to the web of continuous material (W) at the printing station (12). Immediately after the printing station, the image is erased from the device so that a remaining portion of the image may be projected onto its surface. In this manner the device appears to provide a printing surface of indeterminate length and so is designed without relation to the image to be projected. A plurality of such printing stations may be arranged in series for color printing. Furthermore, the operation of the printing station and associated activities may be controlled by a pre-selected computer program.
