CHAPTER 5 100
Reproducing Color Accurately
3
In the Assumed Profiles area, choose which
ICC profiles to use to define the RGB, CMYK,
and Grayscale color spaces to convert from when
opening files that don’t contain an ICC profile.
For example, if an RGB image was previously
saved in Photoshop 4.0 in Mac OS, choosing
Monitor RGB here would open the image using
the same RGB color space it used before. (This
occurs because earlier versions of Photoshop
edited images within your monitor’s color space.)
Note: This feature is disabled for images saved from
Photoshop 4.0.
Choosing Ask When Opening displays a dialog
box when opening a file that doesn’t have an
embedded profile.
4 In the Profile Mismatch Handling area, choose
whether to convert files being opened for which
the embedded or assumed ICC profile does not
match the profiles specified in the appropriate
RGB Setup, Grayscale Setup, and CMYK Setup
dialog boxes.
Choosing Ask When Opening displays a dialog
box when opening a file whose embedded or
assumed profile doesn’t match the setting in the
appropriate Setup dialog box.
Choosing Ignore ignores color information
embedded in a file and opens the file with no color
conversion.
Choosing Convert converts the image to the
chosen color space as defined by the appropriate
Setup dialog box.
Important: Adobe does not recommend automati-
cally converting CMYK images to other color spaces,
because CMYK color space mismatches can cause
color information (such as black generation, under-
color removal, and trapping) to be lost in the image.
For CMYK, you should choose Ask When Opening,
Convert to RGB Color, or Convert to Lab Color.
To open a file when the Profile Mismatch dialog box
appears:
Do one of the following:
•
Click Don’t Convert to open the file without
converting its color space.
•
Click cancel to close the file without converting
its color space.
•
Apply the options described for the Profile to
Profile command. (See Converting the color space
of open images.) Then click Convert to convert the
file’s color space.
Converting the color space of
open images
The Profile to Profile command lets you convert an
open image from any color space to the color
spaces defined in the RGB Setup, Grayscale Setup,
and CMYK Setup dialog boxes.
