PS Gamma Adjuster
You can adjust the halftone density of each CMYK color for this machine. Make adjustments if an image like a
photo is too dark.
For Windows, the [Custom Gamma Adjustment] menu or its content may not be displayed on the [Color] tab of the
printer driver after a name is registered in [Gamma Curve Name]. In such a case, restart your PC.
Using the Gamma Adjuster may slow down the printing. If you want to prioritize the speed, uncheck [Custom Gamma
Adjustment] in the [Color] tab of the printer driver for Windows. For macOS, select [Not Specified] for [Custom
Gamma Adjustment] in the [Print Quality 2] tab on the [Print Setup] panel.
Applications that have been started before registering [Gamma Curve Name] must be restarted before printing.
Some applications allow you to specify dot gain correction and gamma adjustment when printing or include this
setting in an EPS file. To use the functions provided by an application, uncheck [Custom Gamma Adjustment] in the
[Color] tab of the printer driver for Windows. For macOS, select [Not specified] for [Custom Gamma Adjustment] in
the [Print Quality 2] tab on the [Print Setup] panel.
For Windows, the model name is displayed in the "Select Printer" list of the PS Gamma Adjuster. If multiple identical
models exist in the "Devices and Printers", the registered [Gamma Curve Name] is valid for all identical models.
