Paper Abstract

Hardcopy halftone image patterns produced by a high resolution electrophotographic (EP) printer are studied. Reflection optical density is measured as a function of dot area coverage with screen size as a parameter. As screen size increases so does the slope of the optical density curve along with an attendant increase in the size of the saturation region and location of the threshold point. The linear region extends from 10% to 90% tints up to an 81 line screen. A semi-empirical model is used to curve fit the density curves with good results. Auxiliary experiments are discussed involving latent image voltage scans and images produced using only the optics section of the EP printer to give a better understanding of EP process effects.
