When used in combination with the lithographic process, which is based on the repulsion of oil and water , the offset technique employs a flat ( planographic ) image carrier.

    Phototypesetting machines project characters onto film for offset printing. Prior to the advent of phototypesetting, mass-market typesetting typically employed hot metal typesetting – an improvement introduced in the late 19th century to the letterpress printing technique that offered greatly improved typesetting speed and efficiency compared to manual typesetting (where every sort had to be ...
