Understanding color models
Colors can be defined in several different color models, the most common being RGB,
CMYK, and the 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.
•
colors are used when you take output from an RGB device such as a digital
camera or a scanner. Another use of the RGB color model is for displaying colors on
a monitor.
•
colors are what most printers use.
•
, 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
inks). With the Spot Color Matching print option, you can determine
how spot colors are printed at the Fiery:
Spot Color Matching On
uses color tables built in the Fiery to simulate the spot color
with the closest equivalent available using the CMYK toners of the C9800.
Spot Color Matching Off
instructs the Fiery 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 Simulation setting you choose, such as
or
.
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
, such as presentation software, spreadsheets, and word processing
programs, use the RGB color model. They typically transmit only RGB data to the
Fiery.
•
Illustration applications
use both the RGB and CMYK color models, but typically
transmit only CMYK data to the Fiery.
•
Pixel-editing applications
use both the RGB and CMYK color models. They can
transmit either RGB or CMYK data to the Fiery.
