 Adjusting Color with PS Gamma Adjuster Utility
This section explains the PS Gamma Adjuster Utility. You can adjust the half-tone density of CMYK
colors printed by the printer. Use this function if the color in a photograph or graphic is too dark.
Note
● The Windows 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 Windows, [Custom Gamma Adjustment] menu or the contents may not be displayed on the [Color] tab of
the printer driver. In this case, restart your computer.
● 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 FAX] folder.
Reference
● For details on how to install the PS Gamma Adjuster Utility, refer to “Installing Utilities” P.86.
