Electrophoretic Deposition of Liquid Toners in a Plate-Out Cell – An Numerical Analysis
Abstract:This numerical study was inspired by an intriguing experimental observation of some unexpected motion of “toner sheet” in a plate-out cell. In this report, numerical models for electrophoretic deposition of liquid toner are described. It takes into account the space-charge effect. The numerical results indicate that the toner deposition is strongly influenced by the space charge accumulation in a stationary plate-out cell. The motion of “toner sheet” gives a good indication of the charging characteristic of the liquid toner and other charged species, co-ion or counter ion, in the liquid inks. By comparison of numerical and experimental observation of the motion of toner in regular liquid inks, for example, it can be concluded that toner mobility is roughly an order of magnitude higher than the other charged species existed in the inks.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
