Registering the Color Configuration
Overview
When there is a job that is periodically output with the same paper and/or settings, you can register the necessary profiles and settings collectively as "color configuration." Complex color setting is made easy by simply specifying the registered "color configuration" when printing.
Color configuration can be registered by following the next two steps:
Registering the Profile Set
With this function, you save all 9 profiles that are applied to one paper type collectively as a profile set. Operate by following the wizard.
Registering the Color Configuration
Then, register "color configuration," which consolidates several profile sets (used for all paper types for a specific job output) and other color settings information.
Tips
Color Centro allows you to create and save various color output settings as profiles, which can be applied as necessary.
A profile set is a group of the following 9 types of profiles.
RGB source profile, Printer profile, CMYK target profile, RGB-CMYK device link profile (image, graphics, text), and CMYK-CMYK device link profile (image, graphics, text)
• Meaning and Purpose of Color Configuration
In the case of frequently output jobs, by registering the job output settings as "color configuration," you can call the suitable color settings by simply specifying the color configuration when outputting the job, which saves you from repeatedly making intricate settings.
Because you do not need to make the settings from scratch when outputting a job, you can cut time spent on adjusting the settings significantly, not to mention that it saves you from concerns about erroneous settings.
•Register several profile sets, used for all paper types for a specific job output, and other color settings information collectively as "color configuration."
It is also useful for changing the coloration and gradation expression of photographs so as to suit the user's preference.

To specify a color configuration for printing, go to Color Management on the printer driver and select Color Configuration. After the printer driver screen is opened, the color configuration that is set as default with Color Centro is set.
If you are not using color configuration, go to Color Management on the printer driver and make the settings manually in Manual Settings.
To reproduce stable colors, in addition to regular calibration, make other pre-output image quality adjustments as necessary, such as when changing screens or papers or when hue is important. For details, refer to Image quality adjustment using image controller.

Relative Colorimetric: Executes color conversion while regarding the paper color as pure white. The paper color parts are represented as colorlessness after color conversion.
Absolute Colorimetric: Executes color conversion while maintaining the measurement value of the paper color. The paper color parts are represented with the color near the actual paper color after color conversion.
* When you select Absolute Colorimetric, Preserve Mid-Tone and Preserve Solid (except for K) cannot be set.
Preserve Mid-Tone
Reproduces colors composed of single colors using only those colors.
Preserve Solid
Reproduces solid colored parts with the same solid colors as before the color conversion.

Register a Color Configuration
You can create a color configuration with Color Centro and register existing profile sets to activate the color configuration.
The explanation in this section is given based on the premise that profile sets for all necessary paper types have already been created.
As an example, the procedure for creating and registering a color configuration with the following conditions is introduced here.
•There is a job that uses coated GL and colored paper.
•Two types of profile sets: "Sample-coat-GL" for coated GL and "Sample_ColorPaper" for colored paper, are prepared.
•The above two profile sets are registered in a color configuration that is created with the name "Sample_Config."
Start Color Centro, and click Color Configuration on the top screen. (Refer to Start Color Centro.)
The Color Configuration Management screen is displayed.
Click New.
A new color configuration is added to the bottom of the tree with a temporary name new*, waiting for a name change.
Delete the temporary name new* and enter a color configuration name to be registered.
Example: "Sample_Config" is entered as the color configuration name.
From the profile set list on the right, select the profile set to be registered, and drag to the color configuration added to the tree.
Example: Two profile sets: "Sample-coat-GL" for coated GL and "Sample_ColorPaper" for colored paper, are being registered.
Check that the profile sets are added under the created color configuration.
Select the added profile sets and check the settings shown on the right side of the screen.
The correspondence of paper types and profiles, color conversion settings, and other information are displayed.
