Colors can be defined in several different color models, the most common being RGB, 
CMYK, and the PANTONE color matching system. Each model requires a different 
color conversion at the Fiery. These different color conversion workflows are explained 
below.

• RGB source profiles and color rendering dictionaries are used to map RGB colors 

through a device-independent color space to a destination space, either the full 
copier gamut in a short-run printing workflow or CMYK simulation in a color 
proofing workflow.

• CMYK colors are device-dependent. In a proofing scenario, colors specified in 

prepress applications are adjusted so the gamut of the Fiery copier can simulate that 
of the press. In a short-run printing workflow, specifying CMYK colors according to 
the calibrated copier output eliminates the need for simulation during printing. 

• PANTONE spot colors are special inks manufactured to run on an offset printing 

press. Spot colors can be simulated using CMYK copier toners or process color inks. 
Two basic workflows exist for printing PANTONE colors to the Fiery:

Spot Color Matching On instructs the Fiery to match the output of the copier to the 
PANTONE spot color.

Spot Color Matching Off instructs the Fiery to match the copier output to a 
Pantone-specified process simulation. This CMYK combination is then printed with 
the CMYK Simulation setting you choose, such as SWOP or Custom, and CMYK 
Simulation Method set to Full.
