Image Quality: Using Spot Colors
You can use Color Centro to create and edit spot colors.
Using sample data (sample B), you can check the procedure during the actual operation.
• Meaning and Purpose of Spot Colors
Spot colors specified by the application are replaced by and printed in CMYK colors according to the spot color table.
The image controller is provided with a spot color table for printing "DIC," "CF," "HKS," and "PANTONE" spot colors in CMYK colors.
Using Color Centro, you can create, register and edit new spot colors and spot color tables. This function allows you to add custom spot colors that are not registered in the machine's spot color table, and adjust and replace colors that are not reproduced as desired.

•Samples
Sample B: B_sample.pdf
Provided in the "/contents/sample/" folder on the [User's Guide CD] supplied with this machine.
•Workflow
Create and save a new custom spot color that is not registered in the machine's spot color table.
"SampleTable - SampleColor" in "Sample of Color Patch" for sample B is used as an example. Register a spot color called "Sample Color" and print out the original image with its red color replaced with "C100%."
To clearly show the replacement of color, the CMYK color "red" is replaced by "blue" in this example. In actual use, you can use this function to define and replace subtly different colors.
If the spot color is not printed as desired or if you want to replace the spot color with another color, you can edit the spot color to adjust the output CMYK color.
"Pantone 300C" in "Sample of Color Patch" for sample B is used as an example. The blue color in "Pantone 300C" is replaced by "M100%" for printing.
To clearly show the replacement of color, the "blue" color is replaced by "red" in this example. In actual use, you can use this function to adjust and replace subtly different colors.
Apply and print the registered/edited spot color.
•Precautions
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 Pre-output Image Quality Adjustment.
