Rendering styles
The Rendering Style option is used to specify a CRD for color conversions. The following
table describes the various color rendering styles (
CRDs
) provided with RIP Station
software and provides guidelines on when to use each one. Each color rendering style uses a
different gamut mapping method designed for a particular kind of color usage.
CMYK Simulation
The CMYK Simulation print option allows you to print press proofs or simulations. This
option affects 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 ten custom simulations using ColorWise
Pro Tools (see “Using ColorWise Pro Tools” on page 29).
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 DIC,
choose DIC 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 CMYK Simulation setting also determines whether or not CMYK data is affected by
the Rendering Style setting (see page 60).
• With a CMYK Simulation other than None, choose one of the Color Proofing
Rendering Styles.
• With None as the CMYK Simulation, the CMYK data is converted to device-ready color
data using a default PostScript conversion scheme.

ICC rendering style:
Photographic—Preserves tonal relationships in images
rather than exact colors. This rendering style maps out-of-
gamut RGB colors to printable colors in a way that retains
differences in lightness. Color accuracy is sacrificed slightly
in favor of presenting color relationships in the way the
human eye perceives them. Photographic rendering
typically gives less saturated output when printing out-of-
gamut RGB colors than Solid Color rendering does.
Continuous tone photographs,
including scans and images from
stock photography CDs
Image and Contrast and
Perceptual
Presentation—Creates bright saturated colors. This
rendering style does not try to match printed colors
precisely to displayed colors but instead provides vibrant,
dense colors. Photographic images, however, are treated the
same way as by the Photographic rendering style.

Color Proofing (Photo)
— Provides a close match to the
CMYK device being simulated, regardless of the media
being used.
Prepress proofing when a background
color is not desired.
Relative Colorimetric
Color Proofing (Solid)
— Provides the closest match to the
CMYK device being simulated, including rendering the
paper color as the background.
The most accurate prepress proofing.
