The Tutorial for Conversion of Ordinary Image to Duotone Image

What is Duotone?

Duotone is halftone reproduction of image over the other image or picture by the superimposition technique. Traditionally black color will be superimposed over the color pictures.

Duotone is the generic name for multitone printing, which can be done with two, three or four inks. This process requires that the press be set up with special inks, usually PANTONE-designated colors, instead of the standard CMYK inks used for process color printing. Usually the images are printed with a dark base color and a lighter second color, overprinted to fill in, tint and tone the photo or graphic.

Duotone color mode in Photoshop supports between one to four colors of ink. Because home inkjet printers are far better at printing full-color images than black and white, many photographers and designers use Photoshop Duotone processing to improve their artwork/prints. Photoshop's Duotone mode is also commonly used for creating sepia toned prints, using black and yellow inks, sometimes with a third color.
