A technique is described for producing graininess samples using an ordered array binary imaging device with subsequent photographic and lithographic steps. Such samples could be combined to form a visual scale for use in the rapid assessment of solid area noise of electrophotographic images. The potential advantages of this process include high volume production capabilities and the ease of varying image parameters over a wide range. Analytical models for mean density and Wiener spectrum scale value, WS(0), are developed for the ordered array system and are shown to have general applicability. However, these models are neither precise nor accurate enough for use as predictor equations in most practical situations, but considering their simplistic nature, they work quite well in characterizing the ordered array system.
