122 ScanWizard Pro for Mac OS X
When you print the image, the CMS again translates the image data from the
monitor’s RGB color space to the printer’s CMYK color space—using the
information about both devices as stored in their Color Profiles.
So, although all of the devices in this example use different device dependent
color spaces, the CMS is able to translate between them and produce accurate,
predictable color.
What are Device Color Profiles
Color Management Systems use Device Color Profiles to interpret color data
between devices. DCPs are a collection of one or more ICC Profile data files. ICC
Profiles contain color characteristics of a given device (input, display, or output).
ICC profiles conform to the International Color Consortium profile specification,
allowing the same device profiles to be used across multiple platforms.
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
