Alternative Colors (RGB -> CMYK)

Overview

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

Using sample data (sample B), you can check the procedure during the actual operation.

• 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.

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.

  • 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.
