Understanding color models

Colors can be defined in several different color models, the most

(such as PANTONE). Depending on the application you use, you
may or may not have a choice of the color model.

such as a digital camera or a scanner. Another use of the RGB

• CMYK
• Spot
run on an offset printing press. Spot colors can be simulated
using CMYK toners (also known as
Spot Color Matching print option, you can determine how spot
colors are printed at the Fiery:
Spot Color Matching On
simulate the spot color with the closest equivalent available

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 Simulation setting
you choose, such as
The color model used by your application determines the methods
available for choosing colors, as well as the way color data is
transmitted to the Fiery:
•
Office applications
spreadsheets, and word processing programs, use the RGB color
model. They typically transmit only RGB data to the Fiery.
