- noun a photograph or image that originally had continuous tones, displayed or printed by a computer using groups of dots to represent the tones
- The process of converting an image with continuous tones, such as a photograph, into an image with appropriately-spaced dots which simulate the original. When digitally printing a grayscale reproduction of such an image, the greater the number of equally-sized dots per unit area, the darker that particular segment is. Another procedure involves photographing the original through a special screen to obtain the halftone.
