Halftoneteknikken
Halftoneteknikken, or the halftone technique, is a printing method used to reproduce images with continuous tonal variation by means of a grid of small dots. Instead of varying ink density across a smooth tone, the image is represented by the size or density of discrete dots arranged in a halftone pattern. When viewed from a normal distance, the dots visually blend to form shades of gray or color.
The basic principle involves converting a grayscale or color image into a set of interlaced dots. Each
Historically, halftoning emerged in the late 19th century with the development of photomechanical screening techniques. Early
In modern practice, halftoning encompasses several approaches. Amplitude-modulated (AM) halftoning varies dot size on a fixed
