There’s no right or wrong settings, it’s whatever works for you with the ink and media at hand. I turn off ALL Epson default settings like photo enhancement and use the RGB settings. Bump the intensity slider one notch upwards with the premium disc setting and it’s generally pretty good.
If you’re having color matching issues, then you might need to look at your monitor calibration. I use Adobe gamma loader to calibrate my monitor and run in the background.
