Charging Characterization of Colloidal Dispersions by a Plate-Out Cell
Abstract:Charging property of liquid inks is the key in determining the performance in liquid toning. Depending on the charge density and mobility of the toner particles and other charged species in the carrier liquid, the toned images can be formed quite differently. This report describes an approach to obtain the charging property of colloidal dispersions. By bring together the experimentally measured plate-out current, the numerical models are designed to automatically determine the charging characterization of the dispersions. A charge transport model is used in which no change in the charging of all the charged species due to the variation of external field is assumed. The applicability of this method is examined with the experimental data using both regular liquid inks and dispersions of only micelle particles.

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.
