A model of the imaging process involving both the checkerboard process and the analog process of imaging has been developed to describe both the granularity and the grey scale characteristics of the microencapsulated imaging process. The model is shown to provide a quantitative rationale of sensitometric and microdensitometric behavior of the system. The results of the analysis demonstrate that while the analog process governs the grey scale character of capsule images, there is a significant contribution from the digital process. This digital process manifests itself primarily in the granularity characteristics of the image and, except in special cases, contributes relatively little to the grey scale of the image.
