Most applications do not have these color management features and rely instead on the printer or operating system. Operating System Color Management (2). Windows 98, Me, 2000 and XP have Windows ICM color Management.
What this guide describes This user guide only discusses the printer color management system. CM Types 2.jpg If you wish to learn more about your application program or operating system color management, please see the documentation that was supplied with your application software or computer.
Background Information Most applications allow the printer properties to be accessed from within the document print dialog box. Application settings override driver settings. Driver settings override printer menu settings. Color reproduction is a complex topic. This background information explains the factors that affect color matching.
There are many factors that affect color printing. Some of the most important factors are: • the differences between the range of colors a monitor can reproduce versus the range of colors that a printer can reproduce. See page 203. • monitor settings. See page 204.
Page 203
Differences between the range of colors a monitor or printer can reproduce Neither a printer nor a monitor can reproduce the full range of colors seen by the human eye. Each device is limited to a certain range of colors.
Factors that Affect Color Printing Monitor Settings The brightness and contrast controls on your monitor can change how your document looks on-screen. Your monitor color temperature also influences how "warm" or "cool" the colors look. Several of the Color Matching options make reference to your monitor’s Color Temperature.
Software Settings Many software applications have their own color settings. The application settings may override the settings in the printer driver. Please refer to the documentation for your software application for details on how that particular program’s color management functions.
Factors that Affect Color Printing Printer Driver Settings The color settings in your printer driver can change the appearance of a document. There are several options available to help match the printed colors with those displayed on screen. See “How To” on page 216.
Factors that Affect Color Printing Lighting (Viewing) Conditions A document can look very different under various lighting conditions. For example, the colors may look different when viewed standing next to a sunlit window compared to how they look under standard office fluorescent lighting. Paper Type The type of paper used can also significantly affect the printed color.
Your results may vary depending on the application from which you are printing. Some applications override, without warning, any color matching settings in the printer driver. There is no one way to achieve a good match between the document displayed on your monitor, and its printed equivalent.
The CMYK color model is based on Cyan, Magenta, Yellow and Black printer inks or toners. Most documents you print are in RGB format. This is the most common method. If you do not know your document’s color mode, assume that it is RGB.
Choosing a Color Matching Method Matching Photographs RGB only Select a matching method appropriate to your monitor. Windows Natural is generally a good choice.

This option attempts to simulate RGB color. Optimized for matching specific colors, such as a company logo color. The colors within the printer's color gamut are printed without any modification. Only colors that fall outside the printable colors are modified.
Page 215
Hue, Brightness, and Saturation There are three main components to color: Hue, Brightness, and Saturation. The component that determines the frequency of light or the position in the spectrum or the relative amounts of red, green and blue. Hue corresponds to the common definition of color, e.g.
This how-to information explains how to perform color matching with your printer. Color Match Precision When the printer performs color matching, it must do many calculations to convert between different color formats (RGB, CMYK, etc). These calculations can take time to process.
