Abstract

A method and apparatus for the automatic production of business forms, wallpaper, newspapers or the like from a web of continuous printing material comprises an endless movable belt having at least one printing station. An image is projected to a surface of the belt. The image is transferred to the web of continuous material at the at least one printing station. Immediately after image transfer, the image is erased from the belt so that a remaining portion of the image may be projected onto its surface at the printing station. 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. Two more printing stations may be associated with one endless belt for printing two or more colors or two sides of the web. Furthermore, the operation of the printing station and associated activities may be controlled by a pre-selected computer program.
