Using ColorWise and application color management
The Fiery color management system, ColorWise is designed to provide both casual and
expert users the best color output for a variety of purposes. Several applications also
provide their own color management system. This guide describes how to optimize
print output using both ColorWise color management and application color
management.
The Fiery can intelligently manage the printed appearance of RGB, CMYK, and spot
colors. You can allow the Fiery to manage color for most color printing jobs without
adjusting any settings.
A desktop (host-based) color management system uses ICC profiles to convert colors
from one device gamut to another (see Appendix 8). The color data is converted when
it passes from one application to another or when the job is sent to the printer; thus,
the processing occurs on your computer, as opposed to the Fiery.
Conventional color management systems typically address only color conversions,
and they occupy your computer processor. When you use ColorWise, jobs leave
your computer faster, and are processed more quickly on the Fiery.
The advantages to ColorWise color management versus desktop (application) color
management include:
• Relieving your computer from performing additional processing. Delaying color
conversions until the color data reaches the Fiery frees your computer so that you
can continue working, and color conversions on the Fiery are, in most cases, much
faster than similar conversions on a host computer.
• Eliminating the potential for undesirable color management-related conflicts,
such as iterative color conversions and inconsistent color. The Fiery applies global
corrections to specific groups of RGB, CMYK, and spot colors to avoid such
conflicts.
• Accepting RGB files in addition to larger CMYK files from applications, which
minimizes network traffic and enables jobs to print faster.
