Note HP ImageREt 4800 HP ImageREt 4800 is a technology that provides you with the best color print quality without having to change driver settings or make trade-offs among print quality, performance, and memory. The technology produces photorealistic images. ImageREt 4800 provides 4800 dpi color laser-class quality through a multilevel printing process. This process precisely controls color by combining up to four colors within a single dot and by varying the amount of toner in a given area. As a result, ImageREt 4800, together with the 600-by-600 dpi engine resolution, creates millions of smooth colors. In contrast, the single-level printing process found in the default mode of other color laser printers does not allow the colors to be mixed within a single dot. This process, called dithering, significantly hinders the ability to create a wide range of colors without reduced sharpness or visible dot structure. Paper selection To create the best color and image quality, it is important to select the appropriate media type in the printer driver or at the control panel. See "Selecting and using media" on page 77. Color options Color options enable optimal color output automatically for diverse types of documents. Color options use object tagging, which allows optimal color and halftone settings to be used for different objects (text, graphics, and photos) on a page. The printer driver determines which objects appear on a page and then uses halftone and color settings that provide the best print quality for each object. Object tagging, combined with optimized default settings, produces great color out of the box. In the Windows environment, the Automatic and Manual color options are on the Color tab in the printer driver. sRGB Standard red-green-blue (sRGB) is a world-wide color standard originally developed by HP and Microsoft as a common color language for monitors, input devices (scanners, digital cameras), and output devices (printers, plotters). It is the default color space used for HP products, Microsoft operating systems, the World Wide Web, and most office software that is sold today. sRGB is representative of the typical Windows PC monitor today and is the convergence standard for high-definition television. 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" on page 159. The latest versions of Adobe PhotoShop®, CorelDRAW™, Microsoft Office, and many other applications use sRGB to communicate color. Most importantly, as the default color space in Microsoft operating systems, sRGB has gained broad adoption as a means to exchange color information between applications and devices using a common definition that assures typical users will experience greatly improved color matching. sRGB improves your ability to match colors automatically between the printer and the PC monitor and other input devices (scanner, digital camera), without the need to become a color expert. 156 Using color ENWW
