Demonstration of Printwise: a "near-zero" lithographic ink and blanket wash system. 1997.

TURI Technical Report No. 39. This report presents the results of a demonstration of the Printwise lithographic ink and water-based presswash printing system, designed to reduce emissions of Volatile Organic Compounds (VOCs) to near-zero levels. The Printwise system employs vegetable oil-based ink containing a "solubility conversion mechanism" that reacts with the presswash to become water-soluble. Its use could allow printers to reduce or eliminate their major source of VOC emissions: conventional petroleum-based presswash.
