8-2 Page Layout Applications
All RGB images placed in a document are affected by the RGB Source and
Rendering Style settings. The iR C2100/2100S color management system
applies the specified RGB Source setting to all RGB data and then uses the
specified Rendering Style (CRD) to perform a color conversion. An excep-
tion to this occurs if you assign ICC profiles to RGB images using the appli-
cation’s color management tools (see “Tips for advanced users” below). In this
case, the application performs the color conversion of the image and sends
CMYK data to the iR C2100/2100S.
NOTE: To take advantage of RGB Source and Rendering Style settings for
images imported into QuarkXPress 4.02, either save images in the EPS
format, or use Quark’s PrintRGB XTension, which outputs RGB TIFF image
files without converting them to CMYK.
Tips for advanced users
If you place multiple RGB images, some non-photographic and some
photographic, a single CRD may not be suitable for all the images. In this
case you may want the photographic images to bypass the CRD altogether.
To accomplish this, separate the image to CMYK data with a pixel-editing
application such as Photoshop and perform color correction on it. Then save
it as an EPS or TIFF file and import it into the document.
Or you can save the RGB image in TIFF format and assign it an ICC profile
and rendering intent when you import it into the document, if your
application supports this feature.
CMYK simulation
You can specify a CMYK Simulation and a CMYK simulation method for
the job with the CMYK Simulation Profile and CMYK Simulation Method
print options (see page 1-7). The CMYK Simulation setting affects all
CMYK color data sent by the page layout application. It can also affect RGB
data if RGB Separation is set to Simulation.
• If the document contains CMYK images that were separated for an offset
press standard, apply the corresponding CMYK Simulation setting. For
example, for images separated for SWOP, choose SWOP as the CMYK
Simulation setting.
If you print separations to the iR C2100/2100S and choose use the
Combine Separations feature in conjunction with Full Simulation, the
result may not match that of the same page printed as composite.
