Working with Digital Images

Duotone mode. In Duotone mode, one to four custom inks can be used to make up the

colors in an image. Figure 1.14 shows Duotone-mode channels, options, and curves. A

dutone can be used to add a color tint to a black-ink photo printed in a brochure that

uses only black ink plus one other color. A quadtone with custom inks can give a rich

and uniquely colored look to a photograph. Pantone offers reference books that show

sample duotones printed in various inks and their ink percentages.
