GLOSSARY 83 I ICC profile An industry standard color profile format developed by the International Color Consortium (ICC) that describes the color capabilities, including the gamut, of a color device based on the differences between an ideal and the current device. The ideal is often provided by the manufacturer as a color reference file. ICC profiles are implemented on Mac OS computers in ColorSync and on Windows computers in Image Color Matching (ICM). The Color Server color management system, ColorWise, supports ICC profiles. imagesetter Raster-based film output device; a high-resolution laser output device that writes bitmapped data onto photosensitive paper or film.

I
ICC profile
An industry standard color profile format developed by the International Color Consortium
(ICC) that describes the color capabilities, including the gamut, of a color device based on the
differences between an ideal and the current device. The ideal is often provided by the
manufacturer as a color reference file. ICC profiles are implemented on Mac OS computers in
ColorSync and on Windows computers in Image Color Matching (ICM). The Color Server
color management system, ColorWise, supports ICC profiles.
imagesetter
Raster-based film output device; a high-resolution laser output device that writes bitmapped
data onto photosensitive paper or film.
J
JPEG
A graphics file format defined by the Joint Photographic Experts Group committee of
International Standards Organization (ISO); a standard for digital compression of still image
graphic data.
L
Lab
A uniform device-independent color space in which colors are located within a three-
dimensional rectangular coordinate system. The three dimensions are lightness (L), redness/
greenness (a) and yellowness/blueness (b). (Also referred to as L*a*b* and CIELab.)
M
metamerism
Phenomenon in which two colors composed of different combinations of light wavelengths
appear identical under a specific light source, but may look different under other light
sources. The colors are called “metamers.”
moiré
An undesirable pattern in images made using halftone screens. Moiré can be caused by the
improper line frequency of the screens, improper screen angles, improper alignment of
halftone screens, or by the combination of a halftone screen with patterns in the image.
