Abstract: An apparatus and method for supplying emulsion ink to a printing plate on a printing press is disclosed. The apparatus includes an ink feed and recirculation system and associated control system to quickly and reliably form a high quality emulsion ink. The control system utilizes both feedback and feedforward control strategies. The recirculation of the emulsion ink ensures that the emulsion ink remains stable and makes it possible to reformulate the emulsion ink, if necessary, without waiting for the exhaustion of all of the emulsion ink that is in need of reformulation.

Abstract: A container for dispensing sheet material from a roll received interior of the container, the container having a removable end wall for insertion of a roll of sheet material such as film. The container has a slot through a wall portion thereof from which the sheet material can be dispensed, the slot being formed by inwardly bent portions of the material which forms the container body. Removable seal members carried by the inwardly bent portions are coated with a fabric-like material which substantially closes the slot to restrict entrance of light to the interior of the container.
