- A continuous tone image that has been photographed or scanned and then converted into tiny dots whose variations in size create the appearance of variations in tone.
Light areas, or highlights, have small dots and darker areas, or shadows, have larger dots.
Georg Meisenbach (1841-1912) is considered the inventor of halftone technology.
- Traditionally, a halftone screen is a piece of film with a grid of lines (line screen).
It is used to break down continuous tone images, such as photographs, into half-tone images for printing.
The halftone screen breaks down the image into a symetrically aligned series of dots – known as halftone dots.
Nowadays, this process is generally done digitally, via an imagesetter.
