Optimal Photo Printing of Image Data
When people print images taken with digital cameras, they sometimes feel that the printed color tones differ
from those of actual image or those displayed on the monitor.
To get the print results as close as possible to the desired color tones, you must select a printing method
that is best suited to the application software used or to your purpose.
Color Management
Devices such as digital cameras, scanners, monitors, and printers handle color differently. Color
management (color matching) is a method that manages device-dependent "colors" as a common color
space.
For Mac OS, a color management system called "ColorSync" is built into the operating system.
Adobe RGB and sRGB are popularly used as common color spaces. Adobe RGB has a wider color space
than sRGB.
ICC profiles convert device-dependent "colors" into a common color space. By using an ICC profile and
carrying out color management, you can draw out the color space of the image data within the color
reproduction area that the printer can express.
Selecting a Printing Method Suited to the Image Data
The recommended printing method depends on the color space (Adobe RGB or sRGB) of the image data
or the application software to be used.
There are two typical printing methods.
Check the color space (Adobe RGB or sRGB) of the image data and the application software to be used,
and then select the printing method suited to your purpose.
Adjusting Colors with the Printer Driver
Describes the procedure for printing by using the color correction function of the printer driver.
• To print using Canon Digital Photo Color
The printer prints data with color tints that most people prefer, reproducing colors of the original
image data and producing three-dimensional effects and high, sharp contrasts.
• To print by directly applying editing and touch-up results of an application software
When printing the data, the printer brings out subtle color difference between dark and light
areas, while leaving the darkest and lightest areas intact.
When printing the data, the printer applies fine adjustment results, such as brightness
adjustments made with an application software.
Printing with ICC Profiles (Specifying an ICC Profile from the Application Software)
Describes the procedure for printing by using the color space of Adobe RGB or sRGB effectively.
You can print with a common color space by setting up the application software and the printer driver
so that the color management matches the input ICC profile of the image data.
The method for setting up the printer driver differs depending on the application software to be used.
