Abstract

The electrographic marking characteristics of 16-level halftone gray scale images are investigated by calculating the electrostatic latent image density ( i.e. developability ) as a function of the receptor thickness and the pixel size. Both the developability of a solidgray area and the contrast developability between two different gray bar-patterns are considered. The numerical results obtained provide a guideline to determine the ideal receptor thickness for optimum image quality. The image qualities expected from different types ofhalftone patterns are compared.
