							Use a third-party profile
If you have obtained an ICC profile through other means than using the printer’s built-in profiling
software, for instance from an Internet download or a third-party profiling software package, you can
install it for use with your printer and paper.
NOTEThe printer requires RGB output profiles.
The printer needs to know which paper type the profile corresponds to, so you must first select a paper
type from the list of papers it knows about. When choosing a paper type, try to pick one resembling your
actual paper type as closely as possible. The paper type determines the amount of ink to use and other
basic printing parameters, so making a good choice here is fundamental to achieving good results later
on. If you find that you cannot obtain satisfactory results with the profile and paper type you picked, you
can experiment with choosing different types for new paper names corresponding to the same paper,
and use the one that works best.
If the paper you are using is not listed, or you cannot find a paper type that resembles yours closely
enough, you can define a new type. The printer then calibrates itself for use with your paper, after which
you can return to installing the ICC profile.
After you have selected the paper type, browse to the file containing the ICC profile to use with your
printer and paper. Normally, ICC profile file names end in the “.icc” (for International Color Consortium)
or “.icm” (for Image Color Matching) extension. The profile will be stored in the correct system folder on
your computer, and in the printer, as usual.
Profile your monitor
You are also recommended to calibrate and profile your monitor (display device), so that the colors you
see on the screen are more closely related to those you see on your prints. There are two ways to do
this:
●Use the facilities provided with your operating system. From the HP Color Center, select How To
Calibrate Your Display for further information.
●Use the HP Advanced Profiling Solution, which will give more accurate results.
Advanced profiling
To meet advanced color profiling needs, HP offers an optional Advanced Profiling Solution with software
and monitor-calibration hardware at much lower cost than competing solutions.
Color management options
The aim of color management is to reproduce colors as accurately as possible on all devices: so that,
when you print an image, you see very similar colors as when you view the same image on your monitor.
There are two basic approaches to color management for your printer:
●Application-Managed Colors: in this case your application program must convert the colors of
your image to the color space of your printer and paper type, using the ICC profile embedded in
the image and the ICC profile of your printer and paper type.
●Printer-Managed Colors: in this case your application program sends your image to the printer
without any color conversion, and the printer converts the colors to its own color space using a set
of stored color tables. ICC profiles are not used. This method is somewhat less versatile and
adaptable than Application-Managed Colors, but it is a little simpler and faster, and can produce
good results with standard HP paper types.
ENWW Color management options 61

							NOTEThere are only two color spaces that the printer can convert to its own color space
using the stored color tables: Adobe RGB and sRGB if you are using Windows, Adobe RGB
and ColorSync if you are using Mac OS.
ColorSync is the Mac OS built-in Color Management System; so, in fact, when selecting
ColorSync it is the built-in color management part of Mac OS that is performing the color
management, and it is done based on the ICC profiles of specified paper type.
You are recommended to consult the Knowledge Center at http://www.hp.com/go/knowledge_center/
djz2100/ to see how to use the color management options of your particular application.
To choose between Application-Managed Colors and Printer-Managed Colors:
●In the Windows driver dialog: select the Color tab.
●In the Mac OS Print dialog: select the Paper Type/Quality panel, then Color.
●In some applications: you can make this choice in the application.
Color emulation modes
If you want to print a particular print job and to see approximately the same colors that you would get
from printing the same job on an HP Designjet 500/800 series printer, you can use the emulation mode
provided by your printer.
NOTEThis option is available only when printing an HP-GL/2 job with the HP-GL/2 Upgrade.
●In the Windows HP-GL/2 driver dialog: select the Color tab, then Printer Managed Colors, then
select Printer Emulation from the Source Profile list. You can then select from the Emulated Printer
list.
●
Using the front panel: select the Setup menu icon 
, then Printing preferences > Color >
Emulate printer > HP Designjet 500/800 series.
As well as selecting the emulation mode, you must select the paper type that you intend to use. The
available choices are:
●None (no emulation)
●Plain paper (or Bright White Inkjet Paper)
●Coated Paper
●Heavyweight Coated Paper
Color adjustment options
The aim of color management is to print accurate colors. If you perform color management correctly,
then you should be able to print accurate colors with no need of any manual color adjustments.
However, manual adjustments may be useful in the following situations:
●If your color management is not working correctly for some reason
●If you want colors that are subjectively pleasing rather than accurate
The printer driver provides different adjustment facilities depending on whether you are printing in color
or in grayscale.

							Printing in color
You can adjust the colors of your print in similar ways under Windows and Mac OS:
●In the Windows driver dialog: select the Color tab, ensure that the Advanced Color
Adjustments box is checked, then press the Settings button beside it.
●In the Mac OS Print dialog: select the Paper Type/Quality panel, then Lightness and Hue.
Under either operating system, you will then be able to make adjustments using a lightness slider and
three color sliders.
●The lightness slider simply makes the whole print lighter or darker.
●The color sliders can be used to fade or emphasize each of the primary colors in the print. The
primary colors may be red, green, and blue; or cyan, magenta, and yellow; depending on the color
model used in the image.
The Reset button restores each slider to its default central position.
Printing in grayscale
You can adjust the gray balance of your print in similar ways under Windows and Mac OS:
●In the Windows driver dialog: select the Color tab, ensure that the Advanced Color
Adjustments box is checked, then press the Settings button beside it.
●In the Mac OS Print dialog: select the Paper Type/Quality panel, then Gray balance.
Under either operating system, you will then be able to make adjustments using separate controls for
highlights, midtones, and shadows.

							●The lightness slider simply makes the whole print lighter or darker. This slider is available under
Windows in the same window as the other grayscale controls; it is available under Mac OS by
selecting Lightness and Hue.
●The zone definition sliders can be used to define what you mean by highlight, midtone, and shadow.
●The other controls for highlight, midtone, and shadow can be used to adjust the gray balance of
highlights, midtones, and shadows respectively.
The Reset button restores each control to its default setting.
Color management scenarios
The following step-by-step instructions for specific printing jobs using specific software are similar to
those you can find in HPs Knowledge Center on the Web. You are recommended to consult the
Knowledge Center at 
http://www.hp.com/go/knowledge_center/djz2100/ for further examples and for
the most up-to-date information.

Print a black-and-white photo for an exhibition (Photoshop, Mac OS)
This example uses Adobe Photoshop CS2 under Mac OS X and the color management is done by the
printer.
NOTEApplication-managed colors could be used in this example, exactly as in the previous
example. However, printer-managed colors will be used this time, in order to illustrate both
methods of color management.
The recommended approach to creating a black-and-white image is to take a color image and convert
it to grayscale in an image editing program such as Photoshop. In this scenario, however, this conversion

5.(Optional) Use Photoshop to convert the image to grayscale. The simple way is to go to the
Image menu and select Mode > Grayscale.
Alternatively, you can go to the Image menu and select Adjustments > Channel Mixer, to choose
the percentage contribution of each color channel to the grayscale image, as follows:
a.Check Monochrome.
b.Drag any source channels slider to the left to decrease the channels contribution to the output
channel or to the right to increase it, or enter a value between -200% and +200% in the text
box (for example: 30% Red, 59% Green, 11% Blue). Using a negative value inverts the source
channel before adding it to the output channel.
c.Drag the slider or enter a value for the Constant option. This option adds a black or white
channel of varying opacity: negative values act as a black channel, positive values act as a
white channel.
d.Click OK.
