What is stochastic screening?

Answered by Stanley Rosen, Creo Americas, Inc.

What is stochastic screening? Is that the same thing as FM screening and/or staccato screening? If so, why are they called something different? If not, how are they different?

Stochastic screening is a digital screen process that converts images into very small dots of equal size and incorporates variable spacing (or difference in frequency) of these dots to give greater tone range. More dots are "clustered" together for darker tones. This is very often referred to as FM (frequency modulated) screening. There is no difference between the two.

Staccato® is a registered trademark name of FM screening from CreoScitex.
