Aperture 2.1.4: Some exported or printed images may show color shift on Mac OS X v10.6

Resolution

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.

Exporting Images

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:

_{sRGB IEC61966-2.1}

_{Adobe RGB (1998)}

_{CIE RGB}

Note: The above list is not comprehensive; other profiles may also work as expected with 16-bit TIFF export and Black Point Compensation. 

Printing Images

To resolve the issue for printed images, use Software Update to update to Mac OS X v10.6.2:

1. From the Apple () menu choose Software Update.
2. 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.
