The first printed photo using a halftone in a Canadian periodical, October 30, 1869 A multicolor postcard (1899) printed from hand-made halftone plates. While there were earlier mechanical printing processes that could imitate the tone and subtle details of a photograph, most notably the Woodburytype, expense and practicality prohibited their being used in mass commercial printing that used ...
When an image has a transition from light to dark, the error-diffusion algorithm tends to make the next generated pixel be black. Dark-to-light transitions tend to result in the next generated pixel being white. This causes an edge-enhancement effect at the expense of gray-level reproduction accuracy.
A duotone image, made using black and blue in Photoshop. Duotone (sometimes also known as Duplex) is a halftone reproduction of an image using the superimposition of one contrasting color halftone over another color halftone. [1] This is most often used to bring out middle tones and highlights of an image.

Rather than take a postive image and turn it into a negative halftone, the low-budget newspaper process used the same darkroom and the same photograph enlarger to create a positive image which could be placed on a page of typesetting to be photographed by a process camera onto a printing plate (without any additional halftoning.)
A continuous-tone image is one in which each color at any point in the image can transition smoothly between shades, rather than being represented by discrete elements such as halftones or pixels. [1] Many printing methods use discrete halftone dots of cyan, magenta, yellow, and black .
Minor second. A semitone, also called a minor second, half step, or a half tone, [3] is the smallest musical interval commonly used in Western tonal music, [4] and it is considered the most dissonant [5] when sounded harmonically.
In a facsimile system the halftone characteristic is either: . the relationship between the density of the recorded copy and the density of the original, or; the relationship between the amplitude of the facsimile signal to either the density of the object or the density of the recorded copy when only a portion of the system is under consideration.
