[ ] You can also set up the gamma curve by directly entering the gamma value (0.01-
10.00). Use this method when you cannot adjust the gamma value with the menu (p. 46).
Hint
• You cannot use this feature with a Black & White (Line), color or high
definition color file that has been set with ColorSync.
Adjusting the Gamma Value to Match the Display
Normally the gamma setting does not have to be adjusted because Plug-in Module CS-
U has been pre-set with the menu setting to match a true Macintosh display (CRT Type
B). However, if you are using another display and after you adjust the gamma value
with the CRT Type A or CRT Type C setting, and the images are still too light or too
dark, then use the calculation method below to calculate and set the reciprocal value of
the display value.
Sending Output to a Printer
The gamma value does not have to be adjusted for output to a color printer because
the printer driver settings are set to match the display, and matching the gamma
setting of the display does not present a problem. Similarly, the gamma setting does
not have to be done for a monochrome printer.
For fine adjustment, view the image on the display to view the results of your output.
Hint
• If you do not know the gamma setting of your display, refer to the manual
provided with purchase of the display. If you do not find the gamma value in
the manual, or if the manual is not available, contact the manufacturer of
your display.
