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.
