About Color 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. A
color management system is included with operating
systems such as Windows and Mac OS, in addition to
image processing applications. Windows and Mac OS
X include the ICM and ColorSync color management
systems, respectively.
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 the profile 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.
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.
Color Management Print
Settings
You can perform color management printing using
this printer's printer driver in the following two ways.
Choose the best method according to the application
you are using, the operating system environment, the
aim of the print out, and so on.
Setting color management with the applications
This method is for printing from applications that
support color management. All color management
processes are carried out by the application's color
management system. This method is useful when you
want to obtain the same color management print
results using a common application among different
operating system environments.

Setting color management with the printer driver
The printer driver uses the operating system's color
management system and carries out all color
management processes. You can configure the color
management settings in the printer driver using the
following two methods.
❏ Host ICM (Windows) / ColorSync (Mac OS X)
Set when printing from applications that support
color management. This is effective in producing
similar print results from different applications
under the same operating systems.

(Windows)” on page 81

(Mac)” on page 82
❏ Driver ICM (Windows only)
This allows you to perform color management
printing from applications that do not support
color management.
