Stochastic screening

Stochastic screening or FM screening is a halftone process based on pseudo-random distribution of halftone dots, using frequency modulation (FM) to change the density of dots according to the gray level desired. Traditional amplitude modulation halftone screening is based on a geometric and fixed spacing of dots, which vary in size depending on the tone color represented. The stochastic screening or FM screening instead uses a fixed size of dots and a distribution density that varies depending on the color’s tone.
