What do the terms FM (frequency modulated), diffusion and stochastic mean?
• The simplest definition of an FM halftone is: a field of dots that modulate in distances from each other. The term halftone is defined by its context. Halftone is either the generic term for all bitmap fields produced on a printer, or a cluster of micro-dots occurring at regular intervals. • All halftones describe a bitmap by the distance between dots (frequency) and by the size of each dot (amplitude). When amplitude receives the most processing time then that halftone is called a halftone. When the frequency receives most of the processing time then that halftone is labeled as FM, diffusion or stochastic. Many halftones combine frequency and amplitude processing times. These halftones are hard to name and are called by their trademark names or simply hybrids.
