This issue occurs when you use certain printer-specific and custom color profiles and Black Point Compensation is enabled. This issue is resolved in Mac OS X v10.6.2.
This issue occurs when you export to 16-bit TIFF, you are using certain printer-specific and custom color profiles, and Black Point Compensation is enabled. To work around the issue, do any one of the following:
Disable Black Point Compensation in the Export preset. Set the Image Format in the Export preset to something other than TIFF (16-bit). If you choose TIFF, Aperture will export an 8-bit TIFF, which will work as expected. Use a different color profile in the Export preset.
Color profiles which have been tested and work as expected with exported 16-bit TIFF images with Black Point Compensation include:
Adobe RGB (1998)
Note: The above list is not comprehensive; other profiles may also work as expected with 16-bit TIFF export and Black Point Compensation.
To resolve the issue for printed images, use Software Update to update to Mac OS X v10.6.2:
- From the Apple () menu choose Software Update.
- Install the Mac OS X 10.6.2 update.
If you are not able to update to Mac OS X v10.6.2, do any one of the following:
- Disable Black Point Compensation in the Print dialog.
- Change the ColorSync Profile setting to System Managed.
- Choose a different ColorSync output profile.
