Stochastic Stochastic Conventional screening creates the illusion of highlight and shadow by altering the size of uniformly spaced dots. Stochastic screening creates the same illusion with very small, randomly placed spots.
More random spots create shadows and fewer spots create highlights.
The random nature of the spots eliminates the possibility of moire and other conventional screening artifacts. Stochastic screening allows for more photo-realistic reproduction of continuous tone images, smoother screen builds, and sharper fine lines and type simulations.
