Alternative Colors (Changing RGB Colors to CMYK Colors)
You can use Color Centro to register a new alternative color. By enabling the alternative color setting of the printer driver when printing, you can print using alternative colors.
This section introduces how to register the following alternative color for the original RGB color and how to print upon replacing the color.
• Original color: R=0 / G=130 / B=205
• Alternative color: M=100 / Y=100 (red)
Tips
The example in this section is for cases where the original color is an RGB color. For CMYK colors, refer to Alternative Colors (Changing CMYK Colors to Different CMYK Colors).
Meaning and Purpose of Alternative Colors
With the image controller, you can replace any given RGB color or CMYK color with another predefined CMYK color (alternative color) for printing. The original color and the corresponding alternative color are defined in an alternative color table. You can create multiple tables.
Using Color Centro, you can create, register and edit new alternative colors.
Alternative colors are primarily used to change the colors of an illustration or text.
When to perform
When you want to replace a certain RGB color in the original with a specific CMYK color
When you want to use a spot color (CMYK color equivalent to the spot color) with an application that does not allow for spot colors to be used (MS Office, etc.)
Intended Environment
Operating system | Windows 7 |
Application | Color Centro 2.1, Adobe Acrobat Reader DC |
Image Controller | Image Controller IC-605 |
Printer driver | PS Plug-in driver |

Workflow
Precautions
The specified original colors are all replaced by their corresponding predefined alternative colors. Check that the texts, graphics, or images that you want to print in their original colors do not include the colors specified to be replaced by alternative colors. Particularly in the case of RGB colors, use caution to prevent unexpected replacement of colors in images.
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 Adjustment Flow when changing the screen, Regular adjustment flow: Normal and Regular adjustment flow: High Precision.
