Note Factors such as the type of monitor you use and the room's lighting can affect the appearance of colors on your screen. For more information, see Matching colors . The latest versions of Adobe® PhotoShop®, CorelDRAW™, Microsoft Office, and many other applications use sRGB to communicate color. Most importantly, as the default color sp[...]

Managing color options Setting color options to Automatic typically produces the best possible print quality for color documents.

Neutral Grays The Neutral Grays setting determines the method for creating gray colors that are used in text, graphics, and photographs. ● Black Only generates neutral colors (grays and black) by using only black toner. This option guarantees that neutral colors do not have a color cast. ● 4-Color generates neutral colors by combining all four [...]

Matching colors The process of matching printer output color to your computer screen is quite complex because printers and computer monitors use different methods of producing color. Monitors display colors by light pixels using an RGB (red, green, blue) color process, but printers print colors using a CMYK (cyan, magenta, yellow, and black) proces[...]
