Paper Abstract

We quantitatively define a metric of image graininess and derive an analytic expression that relates toner number fluctuations in halftone dots to graininess. We then go on to define the random sequential adsorption (RSA) model, a simple model of particle deposition from which the statistics of development can be numerically calculated. Using the RSA model we find an analytic expression that gives the graininess as a function of toner size. The model is then extended to allow for the effect of a finite toner size distribution. We find that low graininess can be achieved for quite large toners, and the effect of finite size distributions on graininess is minor.
