Chapter 5 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 from 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. Color Management Printing 135

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 from 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.
