Automatic versus Manual color adjustment
The Automatic color adjustment option optimizes the neutral gray color treatment, and the edge enhancements that are used for each element in a document. For more information, see your printer-driver online Help.
Automatic is the default setting and is recommended for printing all color documents.
Use the Manual color adjustment option to adjust the neutral gray color treatment, and the edge enhancements for text, graphics, and photographs. To gain access to the Manual color options, on the Color tab, click Manual, and then click Settings.
