You can define colors in several different color models, most commonly RGB, CMYK, and a spot color matching system (such as PANTONE). Depending on the application you use, you may or may not have a choice of the color model.

RGB colors are used when you take output from an RGB device such as a digital camera or scanner. Another use of the RGB color model is for displaying colors on a monitor.

CMYK colors are what most printers use.

Spot colors, such as PANTONE, are special inks manufactured to run on an offset printing press. Spot colors can be simulated using CMYK toners (also known as process colors). With the Spot Color Matching print option, you can determine how spot colors are printed at the Fiery Server:

• Spot Color Matching On - Uses color tables built into the Fiery Server to simulate the spot color with the closest equivalent available using the CMYK toners of the printer connected to the Fiery Server.

  If your Fiery Server supports the Spot-On application in Command WorkStation, you can customize the spot color definitions used by ColorWise.

• Spot Color Matching Off - Instructs the Fiery Server to simulate the spot color using CMYK equivalents defined by the spot color manufacturer. These are the same CMYK values used by applications that include spot color libraries. This CMYK combination is then printed with the CMYK/Grayscale Source setting that you choose, such as SWOP or DIC.

The color model your application uses determines the methods available for choosing colors, as well as the way color data is transmitted to the Fiery Server:

• Office applications, such as word processing, spreadsheet, and presentation graphics applications, use the RGB color model. They typically transmit only RGB data to the Fiery Server.

• Illustration applications use both the RGB and CMYK color models, but typically transmit only CMYK data to the Fiery Server.

• Pixel-editing applications use both the RGB and CMYK color models. They transmit RGB or CMYK data to the Fiery Server.
