Neutral Grays
The Neutral Grays setting determines the method for
creating gray colors used in text, graphics, and
photographs.●Black Only generates neutral colors (grays and black) by using
only black toner. This guarantees neutral colors without a color
cast. This setting is best for documents and grayscale viewgraphs.
●4-Color generates neutral colors (grays and black) by combining
all four toner colors. This method produces smoother gradients
and transitions to other colors, and it produces the darkest black.
Edge Control
The Edge Control setting determines how edges are
rendered. Edge control has two components:
adaptive halftoning and trapping. Adaptive halftoning
increases edge sharpness. Trapping reduces the
effect of color-plane misregistration by overlapping
the edges of adjacent objects slightly.●Maximum is the most aggressive trapping setting. Adaptive
halftoning is on.
●Normal sets trapping at a medium level. Adaptive halftoning is on.
●Light sets trapping at a minimal level, Adaptive halftoning is on.
●Off turns off both trapping and adaptive halftoning.
Color themes

Setting descriptionSetting options
RGB Color
●Default (sRGB) instructs the product to interpret RGB color as
sRGB. The sRGB standard is the accepted standard of Microsoft
and the World Wide Web Consortium (
http://www.w3.org).
●Vivid instructs the product to increase the color saturation in the
midtones. Less colorful objects are rendered more colorfully. This
setting is recommended for printing business graphics.
●Photo interprets RGB color as if it were printed as a photograph
using a digital mini-lab. It renders deeper, more saturated colors
differently than Default (sRGB) mode. Use this setting for printing
photos.
●Photo (AdobeRGB 1998) is for digital photos that use the
AdobeRGB color space rather than sRGB. When printing from a
professional software program that uses AdobeRGB, it is
important to turn off the color management in the software program
and allow the product to manage the color space.
●None sets the printer to print RGB data in raw device mode. To
render photographs correctly when this option is selected, you
must manage color in the program in which you are working or in
the operating system.

							Match colors
For most users, the best method for matching colors is to print sRGB colors.
The process of matching printer output color to your computer screen is complex, because printers and
computer monitors use different methods of producing color. Monitors display colors by using light pixels
that use an RGB (red, green, blue) color process, but printers print colors by using a CMYK (cyan,
magenta, yellow, and black) process.
Several factors can influence your ability to match printed colors to those on your monitor:
●Print media
●Printer colorants (inks or toners, for example)
●Printing process (inkjet, press, or laser technology, for example)
●Overhead lighting
●Personal differences in perception of color
●Software programs
●Printer drivers
●Computer operating systems
●Monitors
●Video cards and drivers
●Operating environment (humidity, for example)
Keep these factors in mind when colors on your screen do not perfectly match your printed colors.
Match colors using the Microsoft Office Basic Colors palette

HP ColorSphere toner
HP designs the print system (printer, print cartridges, toner, and paper) to work together to optimize print
quality, product reliability, and user productivity. Original HP print cartridges contain HP ColorSphere
toner that is specifically matched to your printer so that it will produce a wide range of brilliant colors.
This helps you create professional looking documents that contain sharp, clear text and graphics and
realistic printed photos.
HP ColorSphere toner produces print-quality consistency and intensity you can depend on across a
wide range of papers That means you can produce documents that help you make the right impression.
Plus, HP professional-quality everyday and specialty papers (including a wide variety of HP media types
and weights) are designed for the way you work.
HP ImageREt 3600
ImageREt 3600 provides 3600 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 3600 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 HPs multi-level printing process, result
in a 600 x 600 dpi printer that provides 3600-dpi color laser-class quality with millions of smooth colors.
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 62.
64 Chapter 8   Color for Windows ENWW
 
						

							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 product, the computer monitor,
and other input devices automatically, and eliminates the need to become a color expert.
