Halftone is a mechanical printing process used to reproduce continuous-tone images using ink. The technique converts shades of grey or colour into a pattern of tiny dots, which vary in size or spacing to simulate the original tones.
Halftone printing is essential in newspapers, magazines, and books, allowing photographs and illustrations to be reproduced accurately with standard printing presses. Understanding halftone helps photographers and designers ensure their images maintain tonal quality when transferred to print media.
