Abstract
Method and apparatus for automatic production of business forms. An image including character data to be included in the form are projected onto a photoconductive surface of a printing cylinder by a plurality of lasers. Toner, in the form of finely grained powder, is applied to the cylinder and the data is thereafter transferred to the web as it is continuously fed past the cylinder. After transfer of the character data to the web, the image is erased so that a new image may be projected onto the cylinder. As a result, printing is not limited by cylinder size, and a continuously varying image may be transferred to the web. As many as four printing or more cylinders may be arranged in series, each applying one of four primary colors to the web. The composition of the forms and the operation of the press are controlled by pre-selected computer programs.
