Disable color management for any imported images that use adaptive or indexed Web-
•
safe color palettes. Images that use indexed color palettes (such as Web-safe palettes)
are like CMYK images in that their color values are already optimized for a specific kind
of output.
Convert RGB and CMYK images to sRGB IEC61966-2.1, the Web standard RGB

color space.
Color-managing colors you create in your document
Any color you apply or create within InDesign automatically uses a default source profile
that corresponds to the color model you used. If you switch color modes, the CMS uses the
appropriate source profiles to translate the color to the CIE LAB gamut, and then to the
new color model you choose. You normally won't need to think about this if you've set up
your default profiles properly.
When defining a process color using a CMS, select your colors from a process color-
matching library. You can ensure that the process colors you specify will be adjusted
correctly for the press by choosing a CMYK source profile that matches your printing
conditions. Changing color management settings or profiles can change the final output
of process colors, because the CMS will adjust the final process color values as necessary.
It can be difficult to exactly reproduce a spot color on a monitor or proofing device,
because many spot color inks exist outside the gamuts of many of those devices.
Changing color values or CMS settings never affects the final spot color, because spot
color inks are premixed. InDesign can color-manage only the density of tints made from a
spot color.
Preparing imported graphics for color management
Use the following general guidelines when preparing graphics in other programs, so that
you can color-manage them in your InDesign document.
Preparing RGB and LAB images
For non-CMYK workflows in which RGB or LAB colors are appropriate until final output
time, use the following guidelines as you prepare RGB and LAB images:
If the other program can embed ICC-compliant profiles, turn that option on before
•
you export.
If you're using a vector graphics program that can export to PDF, consider doing so, to
•
take advantage of color management. You can also import Adobe Illustrator files in
their native format.
To color-manage a bitmap image imported from a program that doesn't support ICC
•
profiles, expect to assign an appropriate profile to the image after you import it into
your InDesign document. (See
images" on page 360.)
To reuse a color graphic for multiple final output devices or media, such as for print,
•
video, and the Web, prepare the graphic using RGB or LAB colors whenever possible.
If you must save in a color model other than RGB or LAB, keep a copy of the original
graphic. RGB and LAB color models represent larger color gamuts than most output
