"Heidelberg Super-Speed platen printing press". ^ a b Museum of Applied Arts & Sciences.Two models of the press were manufactured: the Original Heidelberg 10" x 15" and the larger Original Heidelberg 13" x 18" that can print on larger sheets of paper. Air suction is used to pick up the next sheet of paper from the feed pile, so the blade can grab it as it comes around. The press is driven by an electric motor that runs a flywheel.
Ink can be added to a reservoir, or fountain, which is then spread evenly via several rollers before reaching the rollers which make contact with the forme.
The Original Heidelberg Platen Press also automatically inks the rollers. The platen then opens up to release the printed page and allow the rollers to apply more ink to the forme. When a rotor has moved a page to the platen, the platen is pressed against the forme to make the impression (where ink is transferred from the form to the paper). The forme has the desired image in reverse: with raised parts where the ink is applied, and lowered parts where the ink is not applied. In letterpress an impression is made on the paper by having a platen press the paper against a forme. Ī clamshell-like mechanism performs the actual printing.
HEIDLEBERG LETTERPRESS REGISTRATION
In addition, if the press is set for precision registration ("with gauges"), the feed arm drops the sheet onto moving gauge blocks that then pull it into precise alignment just before the press closes, then picks it back up to carry it to the delivery rack. There are two blades mounted on opposite sides of the rotor (when one blade is picking up the next sheet, the other blade is releasing the previously printed sheet). There are two blades that rotate from the paper feed, where it picks up a sheet of paper to the platen, where the printing impression is made to the delivery rack, where the paper is released followed by the blade pointing straight up ready to start the next cycle. The printing press is most famous for its windmill-like automatic paper feed mechanism. The company later also produced the Original Heidelberg Cylinder Press and today produces offset presses and printing related products. Īlthough the Original Heidelberg Platen Press is no longer being manufactured, it is still in wide use for commercial and enthusiast letterpress printing. The Original Heidelberg Platen Press was introduced in 1914 and manufactured between 19.
