Abstract: A method and apparatus for automatically printing a pattern of features from a plurality of hologram masks on a lithographic machine, which method includes arranging the plurality of hologram masks on first faces of a plurality of prisms such that the pattern of features recorded in each hologram mask can be printed by an exposure beam illuminating second faces of the plurality of prisms; providing an exposure position at which any of the prisms and hologram masks can be arranged such that the patterns recorded in the hologram mask can be printed; providing a prism storage and transport system in which the prisms and hologram masks not at the exposure position can be arranged and for transporting the prisms and hologram masks between any of the exposure position and prism storage positions; and providing a control system for the prism transport and storage system.
