Abstract

The image quality of idealized dot formed line images is viewed from the perceptual attributes of width, width variation, and line sharpness. Expressions are developed which relate these attributes to the image variables of dot reflectance, dot diameter, and dot-to-dot spacing. Trade-offs are outlined between dot diameter/dot spacing, ρ, and dot diameter for these attributes. Regions are defined in ρ-diameter space where one or more of the attributes dominates the perception of these idealized lines.
