If you are using the HP Postscript printer driver for Mac, HP EasyColor technology scans all

documents and automatically adjusts all photographic images with the same improved photographic

results.

In the following example, the images on the left were created without using the HP EasyColor option.

The images on the right show the enhancements that result from using the HP EasyColor option.

The HP EasyColor option is enabled by default in both the HP PCL 6 printer driver and the HP Mac

Postscript printer driver, so you do not need to make manual color adjustments. To disable the option

so you can manually adjust the color settings, open the Color tab in the Windows driver or the Color

Options tab in the Mac driver, and then click the HP EasyColor check box to clear it.

Match colors to your computer screen

For most users, the best method for matching colors is to print sRGB colors.

The process of matching printer output color to your computer screen is complex, because printers

and computer monitors use different methods of producing color. Monitors display colors by using

light pixels that use an RGB (red, green, blue) color process, but printers print colors by using a

CMYK (cyan, magenta, yellow, and black) process.
