Calibrating and Profiling the Display
If more than one supported display monitor is connected, select the display to be calibrated from the Display
listbox. Note that each display has an independent Target.
Click the Calibrate button to start the calibration process. The software will provide instructions for placing the
calibration sensor on the screen and provide updates as the calibration progresses.
Once the calibration process has been completed, an ICC/ColorSync profile will be generated if the Generate
profile after calibration option in the Preferences dialog is selected. The profile will automatically be associated
with the system's Color Management System.
The results of the calibration process will then be displayed in the Information window.
It is also good practice to use the Test Patterns to quickly visually verify the integrity of the calibration.
Profiling the Display
An ICC/ColorSync monitor profile of the display can be generated without calibrating the display by selecting Generate
ICC Profile.. from the File menu. Non-SpectraView displays can be profiled but not calibrated by SpectraView.
Validating the current Calibration
The current state of the display monitor can be measured and compared to the currently selected Target in order
to quickly determine if the current calibration is still accurate, or if the display should be recalibrated. A series of
measurements will be taken on the display and a brief report will be shown of the results. The Information window
will also be updated with a more detailed analysis of the results.
Note: Several factors can influence the results of the validation process and a Delta-E values of 3-5 do not always
indicate that the display needs to be recalibrated. Even very slight differences in the positioning of the sensor from
when it was calibrated, and the length of time the monitor has been powered on, and the basic measurement
repeatability accuracy of the sensor itself, all impact the results. Also keep in mind that the Delta-E value is
comprised of the luminance and color difference. Differences in color are much more critical than a difference in
relative luminance.
