SCREENING ALTERNATIVES -- Screen Out the Competition

However, samples printed with 10 micron stochastic screens were found to exhibit the same degree, or even less, of tone value increase as 20 to 28 micron work despite having more dots. This was because a curve had been applied to the plates, the report continues.

Another factor cited as possibly influencing the amount of tone value increase associated with stochastic screening is spot shape. Spot shapes associated with stochastic screens vary by manufacturer and, in some cases, vary within a manufacturer's screening options.
