Measurement of the Dielectric Properties of Paper
Abstract:Dielectric properties of non-impact printing papers are seldom measured. However, dc resistivity alone does not predict the behavior of paper very well when paper passes through a transfer nip. If the electric field changes with time, all anisotropic frequency-dependent electrical properties of paper should be considered.
We present a new method for the measurement of the electrical properties of paper in the principal directions of the sheet. In the frequency range from 20 Hz–1 MHz, permittivity ε′ and dielectric loss factor ε″ or electrical conductivity σ can be measured. Results on coated and uncoated commercial papers are presented.

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.
