Tel mi about color setting for epson RX680 all-in one because they don give mi the best color.

Hello,
When you say that you are not getting the best results, it depends on many things like
1) The color mode that you might have selected (B&W / color).
2) Document type setting ... Select Graphics for most documents. Select Text if your document has a colored background that you want to remove.
3) Type of Paper you take the print on .. is it a normal paper or a photo paper (there are many types in photo papers again)
Try playing with different settings and you will strike the correct balance that would please your eyes Or please let me know what kind of printout are you taking and what are the present settings so that we can guide you in a better way.

Thanks and Regards,
Srinivas

In your printer settings, (i.e) printer properties..you can access it in the Print window.
printer properties > Advanced > set the color mode to "Epson Vivid" > and Gamma to 2.2

Increase the brightness a little (some 5 points higher), and set the color toggle bars of color catridges to maximum.

Thank you!
