In the past, most newspaper images were woodcuts or wood engravings made from hand-carved blocks of wood, often copied from photographs but more akin to hand-drawn sketches. While there were earlier mechanical printing processes that could imitate the tone and subtle details of a photograph, notably the Woodbury type, cost and practicality prevented their use in mass commercial printing that used relief printing. The first printed halftone photograph in a Canadian magazine, October 30, 1869Ī multicolored postcard (1899) printed from handmade halftone plates. The semi-opaque nature of ink allows halftone dots of different colors to create another optical effect: full-color images. See Film Grain for details.Īs color photography has evolved with the addition of filters and layers of film, color printing is made possible by repeating the halftoning process for each subtractive color – most commonly using what is known as the “CMYK color model”. At a microscopic level, developed black and white photographic film also consists of only two colors and not an infinite series of halftones. This rendition relies on a basic optical illusion: when the halftone dots are small, the human eye interprets the patterned areas as if they were smooth tones. When halftone images contain an infinite range of colors or shades of gray, the halftoning process reduces visual reproductions to an image printed with just one color of ink in dots of varying size (pulse width modulation) or spacing (frequency modulation). “Halftone” can also be used to refer specifically to the image created by this process. Halftone is the reprographic technique that simulates halftone images by using dots that vary in either size or spacing, creating a gradient-like effect. Right: Example of how the human eye would see the points from a sufficient distance. This article is about graphics technology.
