2-18 Using Color Management Workflows
Color Reference Guide for C9800 - 18
Standard recommended workflow
The Fiery controller is highly optimized for the C9800. ColorWise addresses issues
unique to your printer, including screens, individual toner response, interactions
among toners, natural smoothness of blends, and the capability to render spot and
custom colors. The Fiery distinguishes text and graphics from image elements, so that
black channel information is preserved while parameters used for CMYK
color
separations are maintained.
The recommended standard color workflow uses ColorWise calibration and color
management. The Fiery comes into play near the end of the color workflow.
For this workflow:
• Bypass any color management in the applications and printer drivers.
This ensures that the colors you selected reach the Fiery and ColorWise
in a usable form. Keep in mind, however, that ColorWise fully supports color
management from applications and printer drivers (see
“Using ColorWise and
application color management” on page 1-14).
• Set the CMYK Simulation Profile option in ColorWise to match the CMYK color
space used in the application to select the colors. Any CMYK Simulation setting
(except Match Copy, if available) applies calibration, so the response of the printer
will appear to be stable.
The recommended values for CMYK Simulation are SWOP in the U.S., Euroscale
in Europe, and DIC in Japan—choices that reflect the color standard for each
region. If colors have been selected specifically for your calibrated Fiery, set CMYK
Simulation to None.
• Set other ColorWise print options as appropriate. For a list and descriptions of
ColorWise print options that affect CMYK, RGB, spot, and other colors, see the
Color Guide Chapter 1 .
