Latest Patents
Cain's latest patents include a method for the recovery of printing ink wastes. This innovative method greatly reduces the pollution problems associated with the disposal of ink wastes while allowing for the formulation of usable ink products. The process begins by creating a flowable stream of material that includes the ink wastes, which is then directed to a hydroheater along with incoming steam. In the hydroheater, the ink wastes are subjected to elevated temperatures, pressures, and intense shear, resulting in a homogeneous, flowable output. This output can be dried and powdered, allowing it to be reconstituted as a black ink suitable for commercial printing operations. Additionally, the hydroheater output may be treated in a filter press to obtain a filter cake, which can be subdivided and treated with ink carriers to form a processing ink. Notably, this method can directly process dilute printer washup material containing up to 5% by weight residual ink, eliminating the need for preliminary chemical treatment and sludge formation.
