Color setting defaults result in calibrated color outut, if you've selected Enable Color
Management in the Edit > Color Settings dialog box.
The InDesign internal RGB to CMYK conversion results in uncalibrated color output, if
you've deselected Enable Color Management in the Document Color Setting dialog box.
All spot color information is preserved during color conversion; only the process color
equivalents convert to the designated color space. If you're not sure which color choice to
use, consult your prepress service provider.
Leave Unchanged (Export PDF only) leaves each image in its original color space. For
•
example, if the document contains three RGB images and four CMYK images when you
export to PDF, the resulting PDF file will contain the same RGB and CMYK images.
CMYK creates a separable file by representing all color values using the gamut of cyan,
•
magenta, yellow, and black process color inks.
Gray converts all color values to high-quality black-and-white images. The gray levels
•
(shades) of the converted objects represent the luminosity of the original objects.
RGB represents all color values using the red, green, and blue color space. A PDF file
•
with RGB color definitions is better suited for on-screen viewing.
Device Independent (Export EPS and PostScript

enabled color management; it allows an output device to use color management and
profiles to represent colors optimally on that device. For example, InDesign uses source
files for the color conversion, and the separations profile for conversion to CMYK or the
monitor profile for conversion to RGB; otherwise, the InDesign defaults are used.
Process colors created in InDesign are preserved in the exported file; however, process
colors from imported graphics (except placed PDF pages) are converted to the color
mode specified by this option.
Note: You cannot convert color spaces in a placed PDF file. If you intend to create a color-
separable PDF file with placed PDF files that contain RGB color values, do one of the
following: Either return to the creating application and make sure that the document
contains only CMYK graphics, or make sure that color management is on and set up
properly and the output device supports in-RIP separations.
Preview options Determine the characteristics of the preview image that is saved in the
file. The preview image is displayed in applications that cannot display EPS artwork
directly. If you don't want to create a preview image, choose None in the format menu.
Images Specifies how much image data in placed bitmap images to include in the
exported file. For other image options, see
page 369.
High Resolution includes all available high-resolution image data in the exported file

and requires the most disk space. Choose this option if the file will be printed on a high-
resolution output device.
Low Resolution includes only screen-resolution versions (72 dpi) of placed bitmap
•
images in the exported file. Choose this option in conjunction with the OPI Image
Replacement option, or if the resulting PDF file will be viewed on-screen.
