Where Do Color Profiles Come From?
Color Profiles are created by either Kodak scientists or other color
professionals using specialized software packages, sometimes known as
profile building tools.
Kodak scientists use sensitive, specialized equipment to measure the color
characteristics of a representative example of each device, as supplied by
the manufacturer, to determine the intrinsic properties of the device.
From these measurements they develop a "characterization" of the device,
called a Device Color Profile, for each make and model measured.
The Color Profile includes color tables that relates the device's color space
to a Profile Connection Space, as well as information about key attributes
of the device for use by CMS-based applications.
A Word about Source and Destination
People often get confused about what is the "source" of an image and what
is its "destination," so let's clarify this.
In general, the "source" of an image refers to where the image currently
is, and the "destination" is where you want the image to go.
In CMS terms, "source" means the Color Profile used to bring the image
data into the Profile Connection Space (PCS). "Destination" means which
Color Profile is used to get it from PCS to the destination device. For
example, when you scan in an image, you want it to appear on your
monitor. So the source is your scanner, and its related Color Profile, and
the destination is your monitor, using its Color Profile.
