C8800 User’s Guide191 Basics There are three methods by whic h your document’s color can be managed and adjusted: 1. Application Color Management Some graphics and desktop publishing programs such as Adobe Photoshop, Adobe Illustrator, and Quark Xpress have their own built-in color management systems. Most applications do not have these color management features and rely instead on the printer or operating system. 2. Operating System Color Management Windows 98, Me, 2000 and XP have Windows ICM color Management. Mac OS and Mac OS X have Apple ColorSync. 3. Printer Color Management When you print your document and modify settings in the printer driver, the printer performs color adjustments. Important! Only use one color management system if you want the best results from your printer. If you wish to use your prin ter’s color management system, ensure that your applicatio n or operating system color management is switched off. Applying color management in multiple places will give unpredictable results. Downloaded From ManualsPrinter.com Manuals

C8800 User’s Guide195 Factors that Affect Color Printing Monitor Colors vs. Printer Colors Differences between the range of colors a monitor or printer can reproduce Neither a printer nor a monitor ca n reproduce the full range of colors seen by the human eye. Each device is limited to a certain range of colors. •A printer cannot reproduce all of the colors displayed on a monitor. • A monitor cannot reproduce all of the colors printed by a printer. Both devices use very different technologies to represent color. •A monitor uses Red, Green and Blue (RGB) phosphors (or LCDs). • A printer uses Cyan, Yellow, Magenta and Black (CMYK) toner or ink. Very vivid colors (such as intense reds and blues) can be displayed on a monitor. These sa me colors cannot be easily produced on any printer using toner or ink. There are certain colors (for example, some yellows), that can be printed, but cannot be disp layed accurately on a monitor. These differences between monitor colors and printer colors are the main reasons why printed colors do not always match the colors displayed on screen. Downloaded From ManualsPrinter.com Manuals
