Management
This section explains the basics of color management that will help you maximize your printer's
performance and create rewarding work of art (in photographic form).

What is Color Management?

Let's look at the processes involved in printing digital camera photos.
(1) Capture images with a digital camera.
(2) Check the image you want to print and its colors on a computer monitor.
(3) Print it from a printer.
Colors captured with a digital camera, colors that can be displayed on a monitor and colors that
can be printed using a printer cannot be reproduced in the same colors when displayed/printed
on other devices, due to differences between color spaces supported by each device.
The color management system (color matching) is created to uniformly manage device-
dependent colors by using a common color space.
The color management system is generally used to convert each device-dependent color to a
common device-independent color space represented by Lab values (defined by lightness, hue
and saturation), then to color spaces of other devices. The color management system is built into
operating systems under such names as ICM (Windows) and ColorSync (Macintosh).
An ICC (International Color Consortium) profile is required to convert (translate) device-
dependent colors to a color space common to Windows and Macintosh.
ICC profiles are compatible with color spaces for devices such as monitors and printers and
color spaces for digital photo data. By specifying ICC profiles correctly, you can display/print
colors of digital photo data in a common color space.
The flow of color management performed when printing digital photos by using ICC profiles is as
follows:
(1) Captured images are converted to Lab values for a common color space via the input
profile for captured images.
(2) For monitors, the images converted to a common color space are converted to RGB values
via the monitor display profile.
