Tonal gradation is defined with microdots spatially distributed in a carefully randomized manner.
The significantly smaller stochastically screened dots were more susceptible to dust and dirt during film processing. Today a small group of publishers are using stochastic screening, with interest building steadily. Some publishers print single pages stochastically while others run the entire magazine with it. Banta Publications Group is helping to lead the way, printing a number of business and special-interest titles stochastically.
