= Frequency modulated screening. A screening process in the printing sector that works with very small pixels of the same size. The image reproduction is achieved by varying the density of the dots. Light image areas have few pixels, deep image areas more.
In contrast, the conventional amplitude-modulated screening method (AM screening) controls the image reproduction by varying the dot sizes and screen angle. FM screens are not moiré-prone and allow photorealistic half-tone reproduction. An unstable image can appear in smooth surfaces, homogeneous screen surfaces or gradients.
