C7350/7550 User’s Guide: Windows XP Operation • 131 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 is capable of reproducing the full range of colors visible to the human eye. Each device is restricted to a certain range of colors. In addition to this, a printer cannot reproduce all of the colors displayed on a monitor, and vice versa. •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. •A monitor can display very vivid colors such as intense reds and blues. These cannot be easily produced on any printer using toner or ink. Similarly, there are certain colors, (some yellows for example), that can be printed, but cannot be displayed accurately on a monitor. This disparity between monitors and printers is often the main reason that printed colors do not match the colors displayed on screen. 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. Printer Driver Color Settings The driver settings for Manual color can change the appearance of a document. There are several options available to help match the printed colors with those displayed on screen. These options are explained in subsequent sections of this User Manual.

C7350/7550 User’s Guide: Windows XP Operation • 132 Factors that Affect Color Printing Monitor Settings The brightness and contrast controls on your monitor can change how your document looks on-screen. Additionally, your monitor color temperature influences how warm or cool the colors look. There are several settings found on a typical monitor: • 5000k* Warmest; yellowish lighting, typically used in graphics arts environments. • 6500k* Cooler; approximates daylight conditions. • 9300k* Cool; the default setting for many monitors and television sets. *k = degrees Kelvin, a measurement of temperature NOTE Several of the Color Matching options make reference to your monitor’s Color Temperature. Many monitors allow you to adjust the color temperature through their control panels. Downloaded From ManualsPrinter.com Manuals
C7350/7550 User’s Guide: Windows XP Operation • 133 Factors that Affect Color Printing How your Software Application Displays Color Some graphics applications such as CorelDRAW® or Adobe® Photoshop® may display color differently from office applications such as Microsoft® Word. Please see your application’s online help or user manual for more information. Paper Type The type of paper used can also significantly affect the printed color. For example, a printout on recycled paper can look duller than one on specially formulated glossy paper. Downloaded From ManualsPrinter.com Manuals

The guidelines for choosing a color matching method make distinctions between Red, Green, Blue (RGB) and Cyan, Magenta, Yellow, Black (CMYK). Generally, most documents you print are in RGB format.
