SC-T7000 Series/SC-T5000 Series/SC-T3000 Series User's Guide Color Management Printing Color Management Printing 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. 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. 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.

Printing
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. 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.
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.

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.
❏
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.

“Color management printing by ColorSync
(Mac OS X)” on page 87
❏
Driver ICM (Windows only)
This allows you to perform color management
printing from applications that do not support
color management.
