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

  • This function can be used with PS Printer Driver.

  • With Windows, the [Gamma Adjuster] menu or its content may not be displayed on the [Color] tab of the printer driver after registering a halftone adjustment name in [Custom Gamma Adjustment]. In such a case, restart your computer.

  • Using the halftone adjustment may cause printing to become slower. If you want to prioritize speed, uncheck [Gamma Adjuster] check box in the [Color] tab for the windows print driver, or select [None] for [Custom gamma] in the [Quality2] tab on the [Print Options] panel for the Mac OS X printer driver.

  • Applications that were started before registering [Gamma Curve Name] must be restarted before printing.

  • Some applications allow you to specify dot gain compensation and halftone adjustment when printing or have the function that includes such settings in an EPS file. To use such functions provided by the application, uncheck [Gamma Adjuster] check box in the [Color] tab for the windows print driver, or select [None] for [Custom gamma] in the [Quality2] tab on the [Print Options] panel for the Mac OS X printer driver.

  • The "Select Printer" list of PS Gamma Adjuster displays model names. If more than one printer of the same model exist in the [Printer and Device] folder, the registered [Gamma Curve Name] is applied to all same-model printers.
