Device Profiles
Device profiles are the most important part of the color manage-
ment puzzle, because without an ICC profile within your image
chain, you can’t implement color management. Profiles serve
three very important functions:
✦
They describe what color the RGB pixel values actually rep-
resent.
✦
They relate device-dependent RGB values to device inde-
pendent CIELAB/Yxy values.
✦
They contain data to convert between the RGB value that
each device produces, and the CIELAB/Yxy number value.
TECHNICAL NOTE:
CIELAB refers to the Commission Inter-
nationale de l’Eclairage, and L= the “lightness”; A= the posi-
tion of a color on a red-green axis; and B= the position of a
color on a yellow-blue axis. Yxy refers to a specification where
a color is specified by its x and y coordinates on a chromaticity
diagram graph.
