Manage Color
You can manage how colors are handled in your photos by selecting Color Management and ColorSync options from the Print window.
Select Color Management from the pop-up menu.
Color Controls lets you select a color Mode that selects the main method of printing colors for photos and graphics: EPSON Vivid or AdobeRGB.
Gamma adjusts the midtone density in the print.
Advanced Settings adjust Brightness, Contrast, Saturation, and individual Cyan, Magenta, and Yellow color tones.
ColorSync uses standard color profiles for your printer and paper to help match image colors. Select the ColorSync® conversion method and filters in the next step.
Off (No Color Adjustment) turns off printer software color adjustments so you can use the color adjustments in your program only.
If you selected ColorSync as the color management method, select ColorSync from the pop-up menu to continue customizing its use.
When you’re finished, you’re ready to print.
