An improved method for reclaiming waste printing ink is provided wherein waste offset ink is diluted and, thereafter, free water and waste fibrous material is separated through specific gravity differential. A centrifugal method is provided to facilitate separation and to produce an easily disposable waste cake. A heating step is also provided to minimize the quantity of dilutant necessary to reduce fluid friction.
