Digital cameras that shoot images, monitors that display images, and printers that print images each have a different way of creating color. For this reason, there may be a difference between the color of an image when viewed on a monitor and when printed. A color management system is a system for managing color in order to bring these colors closer together. With Digital Photo Professional Ver.4.x, you can more closely match color between different devices using ICC profiles.
This section explains how to adjust monitors and printers that are suitable for color matching. Additionally, information is provided on Digital Photo Professional settings that can be used to take advantage of the color matching setting.
The Color Matching Process
Step 1. Setting the color display of the monitor
Step 2. Setting the application to reflect the monitor and printer settings 
Printing 
The color display of the monitor and the settings for print results can be adjusted to more accurately match each other.White parts in images may appear reddish or bluish, depending on the monitor. This is because the setting value of monitor is not appropriate to display the colors of images. When performing color matching, the value must be adjusted to reproduce the colors of images accurately.
This value is called color temperature and it indicates light colors in units of temperature called Kelvin (K). The default color temperature setting for most monitors is often set at about 9300K; if the value is not changed, it displays overall blue-tinged images. To reproduce white colors accurately, set the color temperature value to "6500K" (if "6500K" cannot be set, select "sRGB").
For information on how to set the color temperature of the monitor, please refer to the instruction manuals for the monitor.
To adjust the colors of monitor more accurately, using a commercially available color-tuning tool for monitors called a "calibrator" is one way. If you use a calibrator, the colors displayed on the monitor are directly measured and you can create a monitor profile (an ICC profile for the monitor). The monitor profile stores the optimum settings for the monitor and automatically applies them to the monitor, which allows you to reproduce the colors in image data accurately.
Measuring monitor colors with a calibrator
When using a calibrator, please note that the color temperature on the monitor must be set to 6500K (or sRGB) in advance. If you set it to another value, such as 9300K, it will not measure correctly.
The following instructions explain the settings for the software that will handle the images.
Start Digital Photo Professional, select [Preferences] in the [Tool] menu.
The [Preferences] dialog box will appear. Select the [ Color Management] tab.
Color Management] tab.
: Default settings of Work color spaceYou can select the color space to be applied as a default setting of RAW images from five types. The color space set will be applied as the color space when a RAW image is converted and saved or printed.
: Color matching settings for display (color setting of the monitor)Where a profile is attached to the monitor you are using, you can display an image in more faithful colors by setting the profile.
- If you select [Use the OS settings], the color profile set in Windows will also be applied in Digital Photo Professional. If you are using multiple monitors, the profile set for each monitor is applied to Digital Photo Professional.
- Select the [Monitor profile], click the [Browse] button. You can select a profile for your monitor in the dialog box that appears.
NOTE
The monitor profile differs depending on the monitor. For details, please see the instruction manual for your monitor. If you used a calibrator, select the profile you created.
: Printing profile (color setting of the printer)Select the profile for the printer (ICC profile for the printer) to be used.
ICC profiles are files containing color information such as color characteristics and color space for various devices, set by the ICC (International Color Consortium). Most devices such as the monitor we use to view images or the printer we use to print images can be managed (color management) using these ICC profiles and the color between different devices can be more closely matched.
Digital Photo Professional has color management that uses these ICC profiles.
IMPORTANT
When you set a profile for printing in Digital Photo Professional Ver.4.x, set the color adjustment function of the printer driver to off. If it is left on, the image may not be printed in colors close to those displayed on screen.
: CMYK simulation profilesA profile that simulates colors when printing in a CMYK environment (printing machine, etc.). With Digital Photo Professional Ver.4.x, you can simulate color with four types of profile.
For more information for profile, refer to the Digital Photo Professional Instruction Manual.
: Rendering intentsRendering intents are color conversion methods when printing an image. The conversion method of each rendering intent is shown below.
- In the [Perceptual] setting, color balance is emphasized. Before and after conversion, all colors are converted to maintain the relationship between colors. Even where colors slightly change, you can print a natural-looking image which has maintained color harmony. However, depending on the image, the saturation may change overall.
- In the [Relative Colorimetric] setting, color gradation is emphasized. There will not be much conversion to colors which are similar before and after conversion, but colors which are not similar are converted appropriately. Because there are little changes to similar colors which comprise most of an image, you can print a natural-looking image in which the saturation has not changed greatly. However, depending on the image, there are cases where the overall tone of an image changes somewhat as colors which are not similar and highlights change.
