An alternative to conventional halftone screening that creates tonal graduations by placing same-size microdots (typically 12 to 30 microns) in a computer-controlled, random order within a given area. The computer uses frequency modulation to vary the number and placement of same-sized dots. The random dot pattern eliminates many moiré problems and allows more than four colors to represent the tones in an image.
A form of electronic dot generation performed by screening algorithms. Frequency modulated or FM screening produces almost continuous tone images with very small dots of equal size and variable spacing.
A silkscreening process that conveys the tone of a screened image by varying the number and location of dots rather than just varying the size of the dots within the grid.
A method that uses a pseudo-random dot size and/or frequency to create halftoned images, but without the visible regularity in the dot patterns found in traditional screening.
A halftoning method in which identically sized microdots appear to be randomly placed, as opposed to the regular grid pattern of conventional halftones; also known as frequency-modulated screening.
non-linear screens
Also known as FM (Frequency Modulated) screening. With conventional halftone screening, the variable dot size formed, creates the optical illusion of various tonal values; however, the dot center pitch distance is constant. In the case of FM screening systems, the dots are randomly distributed to create this tonal change illusion. The greater the number of dots located within a specific area, the darker the resultant tone. The dots produced in this way are usually smaller than conventional halftone dots, resulting in improved definition, although greater care and attention to detail is required in platemaking stage.
a digital screening process that converts images into very small dots (14 to 40 microns) of equal size and variable spacing. Second order screen images have variable size dots and variable spacing. Also called Frequency Modulated (FM) screening
Method of image reproduction that varies the distance between the halftone dots, rather than the size of the dots themselves, to create gray tones; also called FM screening.
Unlike conventional the screen is made up of dots which are randomly distributed to create a tonal change illusion. The greater the number of dots located within a specific area the darker the tone. The dots are usually smaller than conventional screening so the definition tends to be better.
An alternative to conventional screening that separates an image into very fine, randomly placed microdots, rather than a grid of geometrically aligned halftone cells. to top
A screening procedure in which a printable continuous tone structure is produced by varying the dot frequency depending on the tonal values. The dot size remains the same (in contrast to halftone screening). The irregular arrangement of the dots creates a moiré effect.
Screening process that conveys the tone of a screened image by varying the number and location of same-sized dots as opposed to varying the size of dots within rigid grid.
An alternative to conventional screening methods in which an image is color-separated using fine, randomly placed dots rather than geometrically aligned halftone dots.
A method turning images into very small halftone dots that are a uniform size placed at varying distances from one another on films and plates.
A relatively new method for creating halftones. Rather than producing the regularly space dots of lined screens, stochastic screening generates randomly placed dots. Because the generation of the dots is frequently modulated, the technique is also called FM screening. Registration on press is slightly more difficult than with lined screens, but the colors rests can be brilliant.
An alternative to conventional screening that creates tonal gradations by placing same-size micro dots (typically 12 to 30 microns) in a computer-controlled, random order within a given area.
