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 make color 
management settings in the printer driver using the 
following two methods. 
O
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.

Driver ICM (Windows only)
This allows you to perform color management 
printing from applications that do not support 
color management.
