摘要
Xerography consists of a number of complex individual processes which in concert define the image quality of the output print. This paper describes a model which bypasses the complex individual processes and attempts to empirically model the output by use of a few key parameters, motivated by physical insight. Building on a prior modeling approach, a model is defined to empirically fit the microscopic toner mass distribution of halftone patches to measured luminosity (L*) across the Tone Reproduction Curve. The simplified model proposed here accommodates the microscopic toner mass of the patch, the Yule-Nielsen effect on paper, and certain key luminosity measurements. Comparisons are made between the simulated and experimental L* values and the optimization procedure used to fit the parameters is described.
