The influence of the developer drum voltage on screen dot formation

In electro photographic printing with the phase developing, the ink is applied on photoreceptor, and the toner is formed image. In the developing process the voltage influences the toner quality applied on photoreceptor, which primarily influences the future print. The aim of this work is to analyze in details the influence of the developer drum voltage on the process of the black liquid ElectroInk application. Influence on the reproduction of the tinniest printing elements is investigated through the quality of the average screen element by measuring of the optical reflectance. Grayness is examined with the image analysis in the area from 10% to 30% halftone value. The optimal reflectance from the printed dot is achieved with the medium voltage.
