  • Ink conditioning device for removing excess water from emulsions of ink and water during lithographic printing
    Patent number: 5044274
    Abstract: A device for removing excess water from an aqueous emulsion of lithographic printing ink comprises a pair of rollers co-operating together to form a nip. Emulsified ink is fed to the nip and is broken down into an ink phase and an aqueous phase by the pressure exerted by the nip. The aqueous phase is displaced away from the ink phase by gas jets. The ink phase remains on the surface of one of the rollers and is removed and returned to the printing press.
