Management
Even when using the same image data, the
original image and the displayed image may look
different, and the printed results may look
different to the image you see on the display. This
occurs due to the difference in characteristics
when input devices such as scanners and digital
cameras capture colors as electronic data, and
when output devices such as display screens and
printers reproduce colors from the color data. The
color management system is a means to adjust
differences in color conversion characteristics
among input and output devices. As well as
applications for image processing, each operating
system is equipped with a color management
system, such as ICM for Windows and ColorSync
for Mac OS X.
In a color management system, a color definition
file called a "Profile" is used to perform color
matching between devices. (This file is also called
an ICC profile.) The profile of an input device is
called an input profile (or source profile), and of
an output device, such as a printer, is called a
printer profile (or output profile). A profile is
prepared for each media type in this printer's
driver.
The color conversion areas by the input device
and the color reproduction area by the output
device differ. As a result, there are color areas that
do not match even when performing color
matching using a profile. In addition to specifying
profiles, the color management system also
specifies conversion conditions for areas where
color matching failed as "intent". The name and
type of intent vary depending on the color
management system you are using.
User's Guide

Color Management Printing

You cannot match the colors on the printed
results and display by color management
between the input device and the printer. To
match both colors, you need to perform color
management between the input device and the
display as well.
