160 Chapter 14—Glossary

density

A measurement of the ability of light to be absorbed by an ink and paper combination. A darker tone has a higher density than a lighter tone.

density range

The range of density from highlight to shadow on a film negative or positive or on the printed image. It is calculated as the mathematical difference between the densities of the darkest and the lightest tone values.

device

An individual occurrence of a physical device that reproduces an image. Devices have a type and a customer-specified name. Because the declaration of a device does not include its operating conditions—such as ink selection, type of screening, and paper— you cannot measure the color response of a device on its own. (In ICC terminology, the declaration of a device does include its operating conditions.)

device-independent color space

A color space based on human perception of color, measured using a colorimeter or spectrophotometer. The color space is independent of the color capabilities of any specific device. An example is CIELAB. A device-independent color space may be used as an intermediate color space when converting from one color space to another, for example, from CMYK to RGB.

device link profile

A one-way link or connection between two color imaging devices. Such a one-way link can be between devices such as a scanner and a printer, a scanner and a color monitor, or two printers. Using
