摘要： An improved process is provided for the steam conversion of dilute printer ink washup fluids, and especially those of a single color, in order to permit reuse of the ink fraction of the fluids as reconstituted printing inks. Preferably, the washup fluids are acidified to create a pin floc therein, with a final pH of from about 2-7; the acidified fluid is then contacted with a stream of steam in a hydroheater (16) in order to convert the residual ink fraction and permit reconstitution thereof into printing ink. The acidifying agent is preferably an acid polymer or an inorganic acid such as HCl or H.sub.2 SO.sub.4.

摘要： A method for recovery of printing ink wastes is provided which greatly minimizes pollution problems attendant to the disposal of ink wastes, while permitting formulation of usable ink products from the wastes. The method involves first creating a flowable stream of material including the ink wastes, and directing this stream to a hydroheater (16) along with incoming steam. In the hydroheater (16), the ink wastes are subjected to elevated temperatures and pressures, and intense shear, creating a homogeneous, flowable output. This output may then be dried and powdered, and the powder may be reconstituted as a black ink suitable for commercial printing operations. If desired, the hydroheater (16) output may be treated in a filter press (252) to obtain a filter cake (258), and this cake (258) may be subsequently subdivided and treated with ink carriers to form a processing ink. In a preferred embodiment, dilute printer washup material containing up to 5% by weight residual ink therein may be directly processed in the hydroheater (16); this eliminates the need for preliminary chemical treatment and sludge formation.

摘要： Improved compositions for coating paper stock, methods of forming such compositions, and methods of coating paper stock with those compositions are provided. The compositions comprise an aqueous dispersion including therein from about 20-45% by weight filler (e.g., a starch such as wheat starch) and from about 6-18% by weight wheat gluten. Preferably, the gluten is initially modified with a reducing agent so that the average molecular weight of the gluten is less than about 1,000 kDa. The compositions have a viscosity of up to about 2000 cP and a solids content of from about 25-57% by weight, thus making them suitable for high speed coating of paper stock. The finished, coated stock may be conventionally printed to achieve high gloss end products. The compositions are preferably water soluble, thereby greatly facilitating repulping of the coated stock.
