HP ImageREt 2400
ImageREt 2400 provides 2400 dots-per-inch (dpi) color laser-class quality through a multi-level 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. ImageREt 2400 has been improved for this product. The
improvements offer trapping technologies, greater control over dot placement, and more precise control
of toner quality in a dot. These new technologies, coupled with HP's multi-level printing process, result
in a 600 x 600 dpi printer that provides 2400-dpi color laser-class quality with 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.
Media selection
For the best color and image quality, select the appropriate media type from the software printer menu
or from the printer driver.
Color options
Color options automatically provide optimal color output. These options use object tagging, which
provides optimal color and halftone settings for different objects (text, graphics, and photos) on a page.
The printer driver determines which objects appear on a page and uses halftone and color settings that
provide the best print quality for each object.
In the Windows environment, the Automatic and Manual color options are on the Color tab in the printer
driver.
Standard red-green-blue (sRGB)
Standard red-green-blue (sRGB) is a worldwide color standard that HP and Microsoft developed as a
common color language for monitors, input devices (scanners and digital cameras), and output devices
(printers and plotters). It is the default color space used for HP products, Microsoft operating systems,
the World Wide Web, and most office software. The sRGB standard represents the typical Windows
monitor and is the convergence standard for high-definition television.
NOTE: Factors such as the type of monitor you use and the room lighting can affect the
appearance of colors on your screen. For more information, see Match colors on page 39 .
The latest versions of Adobe PhotoShop ® , CorelDRAW ® , Microsoft Office, and many other programs
use sRGB to communicate color. Because it is the default color space in Microsoft operating systems,
sRGB has been adopted broadly. When programs and devices use sRGB to exchange color information,
typical users experience greatly improved color matching.
The sRGB standard improves your ability to match colors between the printer, the computer monitor,
and other input devices automatically, and eliminates the need to become a color expert.
