Duotone

Duotone
A duotone image, made using black and blue inks in Photoshop.

Duotone is a halftone reproduction of an image using the superimposition of one contrasting color halftone (traditionally black) over another color halftone. This is most often used to bring out middle tones and highlights of an image. The most common colors used are blue, yellow, browns and reds.[1]

Now due to recent advances in technology, duotones, tritones, and quadtones can be easily created using image manipulation programs.

History

Duotones hail from Cyanotype and halftone prints. Color images in newspapers and comic books are usually halftone prints and occasionally duotones.

Modern use

Duotone color mode in Adobe's Photoshop uses an imaging process that computes the highlights and middle tones in a black and white image then allows the user to choose any color ink as the second color.

Fake Duotone

A fake duotone, or duograph, is done by printing a single color with a one color halftone over it. This process is generally not preferred over a regular duotone as it loses much of the contrast of the image.
