separated color information for each of the CMYK colors and the

layout. DCS1 format has five separate files. One file acts as the

different channels of CMYK color.

densitometer
An electronic instrument which measures the optical density of film
or reflective media. A transmission densitometer is used to
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.)
