measure films while a reflection densitometer is used to measure
photographs and ink laydown on press sheets.
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
device link profiles helps shorten the conversion path in certain
applications and saves computing time.
device profile
A type of ICC profile that represents the relationship between
colorant tint values of a device and the resulting color. It has two
sets of color mapping tables: one set maps device colorant tint
values to the profile color space while the other set maps the
profile color space to device colorant tint values.
