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.

dot area

The percentage of an area covered by halftone dots, ranging from no dots at 0 percent to a solid ink density at 100 percent. The size of a single dot is stated in a percentage of the area it occupies.

dot gain

A printing effect which results in dots being printed larger than they should be. It occurs as a result of ink spreading on the printed page, and if not compensated for, can lead to an image appearing too dark.

element

Any item within a job—including an input file, page, page set, signature, surface, or separation.
