Color Management
CMYK Simulation
There are several print option settings that affect output when printing press proofs or
simulations. These options affect CMYK data only.
The CMYK Simulation setting specifies the offset press standard or other color gamut
that you want to simulate. You can also create up to five custom Quick simulations and
five custom Full simulations using Print Calibrator (see the Job Management Guide).
The CMYK Simulation setting you should specify depends on the press standard for
which the CMYK data was separated. For example, for images that were separated for
SWOP, choose SWOP-Coated as the CMYK Simulation setting. For images that were
separated using a custom separation (such as a device-specific separation or a
separation produced with an ICC profile), choose None as the CMYK Simulation
setting.
The Match Copy setting bypasses DocuColor 40 CP calibration to simulate the color
of a copy produced by the copier.
The CMYK Simulation Method setting specifies the quality of simulation to perform.
Quick simulation applies one-dimensional transfer curves that adjust output density
only. Full simulation provides a more complete and accurate simulation by applying
four-dimensional transfer curves that adjust hue as well as output density. Depending
on image size and resolution, Full simulation may take more time than Quick
simulation.
Automatic DocuColor 40 CP color management features
Some DocuColor 40 CP color controls are always enabled for optimal color quality.
These color controls, described below, are not affected by print options settings or
Setup options.
Pure Black Text and Graphics
The Pure Black Text and Graphics feature optimizes the quality of black text and line
art by printing one-color black at the full density of your copier. It also minimizes the
amount of toner used when printing documents consisting of a mixture of color and
black-only pages.
