• Using color matching tools—the Fiery provides several tools to
preview colors available on a device and define them within an
application.
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.
• RGB 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.
• 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 color 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 ES3640e MFP.
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
SWOP or DIC .
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.
