This thesis addressed the question of what level of resolution was obtainable from the electrostatic plate. Resolution was defined as the ability of a material to record fine detail. Two types of plates were compared, one photomechanical and the other an electrostatic. The photomechanical plate consisted of a light sensitive coating applied to an aluminum1 base . The electrostatic plate consisted of a fused toner image on an aluminum base. The intent of this research was to determine the final resolution, not the forces and factors which effected it. The hypothesis stated that the resulting resolution of the electrostatic plate will be lower than that of the photo mechanical plate. This research addressed the following questions; What minimum and maximum percent dot, and maximum screen ruling could the plate produce?
