T E R M M E A N I N G
Adobe RGB An RGB working space that provides a relatively large gamut of colors and
is well suited for documents that will be converted to CMYK.
Camera Raw A camera manufacturer's proprietary format that captures all of the raw
camera sensor data, along with metadata, that describes the camera
settings.
CIE Commission Internationale de l'Eclairage. This committee developed a
color model based on human vision.
Color conversion The process of translating color values from one color space to another.
Color gamut The total range of colors produced by a device. A color is said to be "out
of gamut" when its position in one device's color space cannot be directly
translated into another device's color space. For example, the total range
of colors that can be reproduced with ink on coated paper is greater than
that for uncoated newsprint, so the total gamut for uncoated newsprint is
said to be smaller than the gamut for coated stock. A typical CMYK gamut
is generally smaller than a typical RGB gamut.
Color settings file A color settings file (CSF) controls the key aspects of each application's
color management behavior. Adobe Creative Suite 2 comes with several
CSFs—each based on a common workflow—that offer preset color man-
agement policies and default profiles.
Color space A color space is a model for representing color in terms of intensity values;
a color space specifies how color information is represented. It defines a
one-, two-, three-, or four-dimensional space whose dimensions, or com-
ponents, represent intensity values.
Destination profile An ICC color profile representing the device or color space for which color
values are converted in order to preserve color appearance.
ICC International Color Consortium (ICC), the group established by eight indus-
try vendors (including Adobe Systems) for the purpose of creating, pro-
moting, and encouraging the standardization and evolution of an open,
vendor-neutral, cross-platform color management system architecture. For
more information, visit the ICC web site at www.color.org.
ICC profile A file describing the color gamut and reproduction characteristics of a
device, such as a scanner, monitor, or printer by mapping color values to a
device-independent color space like CIE XYZ or CIELAB.
Rendering intent The method used for mapping colors from one device's gamut to that of
another. The four methods are Perceptual, Saturation, Relative Colorimet-
ric, and Absolute Colorimetric.
Source profile An ICC profile describing the color gamut and reproduction characteristics
of a device or color model from which images are captured, scanned, or
stored, such as a digital camera, scanner, or standard working space.
sRGB A standard working space developed by Microsoft and Hewlett-Packard
describing the color of the "average" or "standard" home computer
monitor.
U.S. Web Coated A CMYK working space profile based on the U.S. standard for publication
(SWOP) v2 printing presses, governed by the Specifications for Web Offset Publica-
tions (SWOP). This standard was developed in 1972 for publications such as
magazines and catalogs printed on offset presses.
Working space Default ICC profiles used by the application for the RGB, CMYK, or Grayscale
color models.
