Repeat the process of matching the two halves of the screen as described above and
again, click on the ‘Next’ step button
8
Repeat the process a further eight times to match all ten sets of grey patches. If the patches
are too dark to see any differences, just click on the ‘Next’ step button
Î
Note that it is possible to step back to a previous grey level at any time by clicking on the
‘Prev’ step button
Once all the patches have been matched, the monitor calibration data must be saved:
9
Click on the template button to choose a calibration template appropriate to the type of
monitor you have (currently, Apple Cinema and CRT displays are supported).
The template list will also include any existing monitor calibration files, including ones created
using a Truelight Monitor Probe. You can use a previous calibration as a template. The new
calibration will have new RGB tone curves, but the other display properties are inherited from the
template file.
10 Type a file name for this monitor calibration data in the calName box, and then click on the
‘Save’ button
(note that the default name for this file is ‘monitor’).
Note that if the chosen calibration file already exists, a warning message will appear asking
whether you want to overwrite it. Cancel if you do not.
The calName box has a browser control. You can put calibrations in other directories, but
the default directory is where Truelight will expect to find them.
The monitor has now been calibrated for use with Truelight and the ‘TLCalibrate’ node can be
deleted.
Warning: If you alter the display controls now, your new calibration will be invalid. Please lock or
disable any controls on your monitor, if you can.
Note that the calibration tool only calibrates the tone curves. It cannot measure the absolute
brightness or colour of your monitor. The standard Apple Cinema and CRT templates use the
Truelight default white point (16 foot-lamberts D65). If you are using a Truelight Monitor Probe
calbration as your template, then you will get the correct absolute white point for your monitor.
