Use color
The HP Color LaserJet CP3505 printers provide automatic color features that generate excellent color
results. Carefully designed and tested color tables provide smooth, accurate color rendition of all
printable colors.
The printers also provide sophisticated tools for the experienced professional.
HP ImageREt
HP ImageREt is a technology that provides the best color print quality without having to change printer
driver settings or make trade-offs between print quality, performance, and memory. ImageREt produces
photorealistic images.
The HP Color LaserJet CP3505 printers use HP ImageREt 3600 technology, which offers trapping
technologies, control over dot placement, and more precise control of the toner quality in a dot.
HP ImageREt 3600 produces a 600x600 dpi print resolution that provides 3600-dpi 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 control panel.
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 107 .
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.

							Print in four colors (CMYK)
Cyan, magenta, yellow, and black (CMYK) are the inks that a printing press uses in four-color printing.
Graphic arts (printing and publishing) environments typically use CMYK data files to provide rich,
saturated colors for text and graphics. The printer uses the PS printer driver to accept CMYK colors.
CMYK ink-set emulation (PostScript only)
The HP Color LaserJet CP3505 printers use CMYK color rendering to emulate several standard offset-
press ink sets:
●Default CMYK+: This selection is good for general-purpose rendering of CMYK data. It is designed
to render photographs well while providing rich, saturated colors for text and graphics.
●Specifications for Web Offset Publications (SWOP): This selection replicates the common ink
standard in the U.S. and other locations.
●Euroscale: This selection replicates the common ink standard in Europe and other locations.
●Dainippon Ink and Chemical (DIC): This selection replicates the common ink standard in Japan
and other locations.
●Device: This selection turns off emulation. Color must be managed in the software program or
operating system in order to render photographs correctly.

Manage color
Setting color options to Automatic typically produces the best possible print quality for color documents.
However, you sometimes might want to print a color document in grayscale (black and white) or change
one of the printer color options.
● In Windows, use the settings on the 
Color tab in the printer driver to print in grayscale or change
the color options.
● When using a Macintosh computer, use the 
Color Matching pop-up menu in the  Print dialog box
to print in grayscale or change the color options.
Print in Grayscale
Select the  Print in Grayscale  option from the printer driver to print a color document in black and white.
This option is useful for printing color documents that will be photocopied or faxed.
When  Print in Grayscale  is selected, the printer uses the monochrome mode, which reduces wear on
the color cartridges.
Automatic or manual color adjustment
The  Automatic  color adjustment option optimizes the neutral-gray color treatment, halftones, and edge
enhancements for each element in a document. For more information, see your printer driver online
Help.
NOTE: Automatic  is the default setting and is recommended for printing all color documents.
Use the Manual color adjustment option to adjust the neutral-gray color treatment, halftones, and edge
enhancements for text, graphics, and photographs. To gain access to the manual color options, from
the  Color  tab, select  Manual, and then select  Settings.
Manual color options
Use manual color adjustment to adjust the  Color (or Color Map ) and Halftoning  options individually
for text, graphics, and photographs.
NOTE: In programs that convert text or graphics to raster images, the  Photographs settings also
control text and graphics.

Halftone
Halftone options affect the color output resolution
and clarity. ●
Smooth
 provides better results for large, solid-filled print areas
and enhances photographs by smoothing color gradations. Select
this option when uniform and smooth area fills are the top priority.
● Detail
 is useful for text and graphics  that require sharp distinctions
among lines or colors, or images that contain a pattern or a high
level of detail. Select this option when sharp edges and details are
the top priority.

Setting descriptionSetting options
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.
● 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
 is the default trapping setting. Trapping is at a medium
level and adaptive halftoning is on.
● Light
 sets trapping at a minimal level, and adaptive halftoning is
on.
● Off
 turns off both trapping and adaptive halftoning.
RGB Color
●Default (sRGB)
 instructs the printer 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 ).
● Image optimization (sRGB)
 instructs the printer to use the best
color matching for rendering sRGB images. Select this option to
print raster objects, such as .BMP, .TIF, or .GIF files.
● Adobe RGB (1998)
 instructs the printer to use the best color
matching for documents or images that are in the Adobe RGB color
space that some digital cameras and high-end graphics programs
create. When printing with Adobe RGB from a professional
software program, turn off the color management in the program
and allow the printer software to manage the color space.
● None
 instructs the printer to print RGB data in raw device mode.
You must manage color in the program in which you are working
or in the operating system in order to render photographs correctly
when this option is selected.
● Custom Profile
 instructs the printer to use a custom input profile
to more accurately predict and control color output. Download
custom profiles from 
http://www.hp.com .
Color access and control
The HP Color LaserJet CP3505 printers include a  RESTRICT COLOR USE setting for networked
printers. A network administrator can use this Color Access and Control setting to restrict user access
to the color printing features to conserve color toner. If you are unable to print in color, contact your
network administrator.

							Match 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.
For most users, the best method for matching colors is to print sRGB colors.
Sample book color matching
The process for matching printer output to preprinted sample books and standard color references is
complex. In general, you can obtain a reasonably good match to a sample book if cyan, magenta, yellow,
and black inks are used in the sample book. These are usually referred to as process-color sample
books.
Some sample books are created from spot colors, which are specially created colorants. Many of these
spot colors are outside the printer gamut (color range). Most spot color sample books have companion
process sample books that provide CMYK approximations.
Most process sample books have a note about what process standards were used to print the sample
book: SWOP, EURO, or DIC. In most cases, for optimal color matching, select the corresponding ink
emulation from the printer menu. If you cannot identify the process standard, use SWOP ink emulation.
Print color samples
To use the color samples, select the color sample that is the closest match to the desired color. Use the
sample’s color value in your program to describe the object that you wish to match. Colors can vary
depending on paper type and the software program used.
