ABSTRACT:
An ink package comprising a disposable container is provided for supplying ink to an ink fountain of a lithographic duplicating machine and includes a self-contained, sealed package provided with specially configured nozzle means for dispensing ink from the container directly into an ink fountain. The ink used in the container is designed to be within the higher ranges of flowability for lithographic ink, and hence, due to special design of the nozzle aperture or apertures, is able to flow sluggishly from the container by gravity, whenever the nozzle means is exposed to the atmosphere, to spread longitudinally of the fountain roller, and to form an elongate bead of ink which increases in size until it blocks exposure of the nozzle means to the atmosphere and thereby shuts off flow from the nozzle means. Thus, a substantially constant volume of ink is maintained in the ink fountain as long as any ink remains in the container.
