Frequency-modulated screening. A type of screening that employs irregular clusters of equally sized CMYK pixels to represent continuous-tone images. The placement of these pixels, although seemingly random, is precisely calculated to produce the desired hue and intensity. This process differs from traditional halftoning in which the distance between CMYK dots remains constant while dot size varies to create the desired hue and intensity. Compare AM screening.
frequency modulation screening - A means of digital screening. See also stochastic screening.
A dithering method that uses uniform dot sizes and varies the distance between them. This method is different from conventional halftone screening, which aligns dots of varying sizes on a regular grid.
A means of digital, or stochastic screening. Images are formed by increasing or decreasing dots of a predetermined size.
Screening method for the simulation of continuous tones involving the arrangement of same-size dots at varying distances. The number of dots in a defined area determines the color tone. Though the quality of this kind of simulation is high and no moiré patterns are created, it requires somewhat better accuracy and care in platemaking and printing as well as different work methods. In addition, color areas sometimes appear grainy.
