1. Calibrating multiple monitors
SuperCal is not yet multiple-monitor aware, but it can be used in a multiple-monitor configuration. SuperCal currently operates on the non-mirrored, main display which is the display containing the menu bar. In order to calibrate a secondary display, use the Monitors control panel (under Mac OS 9) or Display panel in the System Preferences (under Mac OS X) to move the menu bar to the secondary display to make it the main display, then run SuperCal again. You may need to restart after changing the main display because not all systems update their configuration properly after re-arranging displays. For example, there appears to be a bug in Mac OS X 10.0 thru 10.1 on a PowerBook using the external video that does not update the video configuration properly after a display arrangement change. In this case, a restart is required for the video hardware to configure itself properly.
In addition, you cannot calibrate with video mirroring turned on. However, you can calibrate and generate a profile for each display individually, then turn mirroring on and assign the each profile to its respective display using the Monitors control panel (under Mac OS 9) or Display panel in the System Preferences (under Mac OS X).
2. Changing display settings while calibrating
SuperCal is not Display Manager aware, so changes in display settings (like color depth and resolution) while the application is running is not suggested. If you need to change these settings when calibrating, quit SuperCal, make the changes, then relaunch the application.
3. Chromatic adaptation
SuperCal does not do chromatic adaptation of the white point tristimulus values in the profile. The tristimulus values will be correct for the display's native white point, but they will not be correct if you do a white balance adjustment in SuperCal or adjust your display's color temperature to a setting other than its default using a hardware settings. This wil have no visible effect on the screen, but will affect color management applications that use the white point value of the media for color correction.
4. File names
Because SuperCal is a Carbon application, file names are currently limited to 32 characters.
5. Have a corrupted profile?
If you suspect there is a problem with a profile, we suggest you use the "Profile First Aid" feature in the ColorSync Utility application to help diagnose any problems. This utility is located in the following folder: /Applications/Utilities/ColorSync Utility. If you find an issue with a profile generated by SuperCal, please email us at support@bergdesign.com and attach the profile so that we can investigate the problem.
6. Important fix for old v1.1 or v1.1.1 profiles...
We discovered a mistake in the display color data for certain displays in version 1.1.1 and earlier. The color data was not properly adapted to the D50 illuminant of the profile connection space, and as a result, ColorSync-aware applications such as Photoshop may report the profiles as defective. The mistake will only be apparent if you use these old profiles in ColorSync-aware applications.
Updating your old profiles is very easy to do and does not require you to repeat any of your measurements. The following steps will update the tristimulus data while leaving your previous calibration data intact.
If you have more than one profile, repeat these steps for each of the profiles you have created with SuperCal.
Your profile(s) will now have the correct display color data in it. This technique will be useful in the future as we improve the improve the accuracy of the color data and include new display models that are not listed in the latest version of SuperCal.
