What is Stochastic Screening? | Brumley Printing

2016-10-27 · Stochastic screening (also frequently referred to as FM (frequency modulated) screening) developed in the 1970s. Stochastic screening is a commercial printing method that produces more lifelike tonal representations, and a broader CYMK color gamut than traditional halftone, or AM (amplitude modulated) screening does not.

Stochastic Screening - PrintWiki

2019-4-17 · Stochastic screening exhibits frequency modulation, which means that the frequency of the dots is modulated or varied, while the size remains constant. (For this reason, stochastic screening is also known as FM screening .) Stochastic screens utilize microdot s which are typically 15:20 microns in diameter and vary in line count by the tonal ...

New Screening Techniques for CTP - WhatTheyThink

2006-10-29 · Frequency modulated (FM) screening or stochastic screening uses a different approach than AM, holding dot size constant and varying the distance between dots. Because the dots are smaller and closer together over most of the tonal range, FM screening results in more apparent detail in the midtones and also removes a major source of moiré patterns.

The Good, The Bad and the 4 Ugly’s of Stochastic Screening

The FM waves are equally high but spaced differently with resulting equal size dots that are variable spaced (it helps to draw it). The Good News. There are a number of benefits of FM technology. Since stochastic screening does not employ screen angles, moires due to the interfaces of patterns from screening are eliminated.

AM Screening Vs FM Screening : Advantages and ...

2018-8-30 · AM screening and FM screening both has its advantages and disadvantages. In general FM screening are more suitable for details images, highlights, and shadows. AM screening performs better in mid-tones. FM are more consistent in its ink delivery, therefore, some say that it is able to produce a very stable appearance.

2009-3-31 · FM screening — also called stochastic screening — is a way to print a tint of a color more like an inkjet than a traditional halftone. That is, instead of a regular grid of spots that get bigger (in darker areas) or smaller (in lighter areas), you make a bunch of tiny spots closer together in darker areas and farther apart in lighter areas.
