3. Using Utility Software
Adjusting Color with PS
Gamma Adjuster Utility
This section explains the PS Gamma Adjuster
Utility. You can adjust the half-tone density
printed by the printer. Use this function if the
color in a photograph or graphic is too dark.
Note
● The Windows PCL/XPS printer driver cannot be used.
● Printing speed may be slow if this function is used. If you
want to prioritize the speed, select [Not Specied] from
[Custom Gamma Adjustment].
● Some applications can specify the half-tone settings. If
you use these functions, select [Not Specied] from
[Custom Gamma Adjustment].
● If you are using an application before registering the
half-tone adjustment name, restart the application before
printing.
● The registered half-tone adjustment name is effective for
all printers of the same type if multiple printers are saved
in the [Printers and Faxes] folder.
Reference
● For details on how to install the PS Gamma Adjuster
Utility, refer to “Installing Utilities” P.86.
