Calibrating and Proling 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 prole will be generated if the Generate prole
after calibration option in the Preferences dialog is selected. The prole 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.
Proling the Display
An ICC/ColorSync monitor prole of the display can be generated without calibrating the display by selecting Generate
ICC Prole.. from the File menu. Non-SpectraView displays can be proled 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 inuence 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 dierences 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 dierence.
Dierences in color are much more critical than a dierence in relative luminance.
