Halftone is a graphic design technique used to reproduce an image by using dots of varying length with one or more colors. It enables image display similar to a continuous tone-like image but on a pixelated or halftone background.
Halftone is a type of static visual effect applied on digital and print images. It works on a very simple principle, where each pixel in an image area is considered a dot with different sizes, some of which take up more space than one pixel. When a picture/image is converted to halftone, the image texture appears as if it has been pasted on top of a collection of infinite but non-continuous dots. The dots are actually not unlimited but equivalent to the image's total resolution. The resulting image/picture is known as a halftone image.
