2-6 Simple and Advanced Workflows
The iR C2100/2100S comes into play near the end of the color workflow. To
ensure that the colors you have selected reach the iR C2100/2100S and
ColorWise in a usable form, you should bypass any color management from
applications and printer drivers. Keep in mind, however, that color
management from applications and printer drivers is fully supported by
ColorWise (see "Advanced workflows" on page 2-7).
You must print with the CMYK Simulation print option set to match the
CMYK color space in your application when you selected the colors. Any
CMYK Simulation setting (except Match Copy) applies calibration, so the
response of the copier/printer will appear to be stable.
The recommended values for CMYK Simulation are SWOP in America,
Euroscale in Europe, and DIC in Japan—choices that respect the color
standard for each region. If colors have been selected specifically for your
calibrated copier/printer, set CMYK Simulation to None.
See the table on page 1-3 for the list and descriptions of ColorWise print
options affecting CMYK, RGB, PANTONE, and other colors.
Workflow 3 bypassing ColorWise—not recommended
Bypassing ColorWise color management, while an option, is not a
recommended workflow. When you bypass ColorWise, you must choose
colors using only CMYK formulas designed specifically for your copier/
printer, and you must print with the CMYK Simulation option set to Match
Copy. The iR C2100/2100S still prints pages using your PostScript files, and
drives the copier/printer and its accessories, but it does not perform CMYK
color transformation, nor does it consider the calibration of the copier/
printer. Calibration is needed in order to get consistent output, since the
color response from your copier/printer varies significantly depending on
wear, heat, humidity, and service.
The diagram below indicates that no modifications are made to colors in this
workflow.
