							In order to print accurate colors, it is necessary to convert the color values in your files to the color values
that will produce the correct colors from your printer, your inks and your paper. An ICC color profile is
a description of a printer, ink and paper combination that contains all the information needed for these
color conversions.
When you have defined and calibrated a new paper type, the printer is ready to create a ICC profile for
use with your paper, which will allow you to print on it with the best possible color accuracy. Alternatively,
if your paper type is already known to the printer, you already have an appropriate ICC profile for use
with it.
Create your own profile
You can create a color profile easily by using the HP Color Center: select Paper Preset
Management > Profile Paper. The printer helps you by prompting for information about the paper, then
creates and installs the new profile automatically.
The process takes about 15–20 minutes and consists of the following steps.
1.A profiling chart is printed, which contains patches of each ink used in your printer. Unlike a
calibration chart, most of the patches contain combinations of more than one ink.
The printer chooses automatically between two profile charts:
●An A3 or B format for cut sheets
●A roll-paper format that minimizes paper use by printing across the full width of the roll
2.The chart is allowed to dry for a period of time that depends on the paper type, so that the colors
have time to stabilize.
NOTE:If you would like to use a longer drying time, you can ask the HP Color Center to create
the chart without going on to create a profile (Windows: Print target only; Mac OS: Print ICC
profiling chart). Then, later, when the chart is completely dry, you can restart the HP Color Center
and ask it to create a profile using the chart you have already created (Windows: Create ICC profile
from a target that has already been printed; Mac OS: Scan ICC profiling chart and create ICC
profile). In this case the spectrophotometer takes a while to warm up before it is ready to scan.
3.The chart is scanned and measured using the HP Embedded Spectrophotometer.

							NOTE:Chart measurement may not be successful if you load the chart as a single sheet without
skew check.
4.From the measurements made by the spectrophotometer, the printer calculates the ICC profile for
your printer, inks and paper type.
5.The new ICC profile is stored in the correct system folder on your computer, where your application
programs can find it.
The profile is also stored in the printer, so that other computers connected to the same printer can
copy it. The HP Printer Utility will notify you if your printer has profiles that are not yet stored on
your computer.
NOTE:Some applications may need to be closed and restarted in order to use a profile that has just
been created.
You can profile a photo paper with the gloss enhancer on or off. The two profiles will be different, so you
are recommended to save them under different names.
Color measurement
You can also create a color profile by using a third-party profiling program and the Color Measurement
facility. To begin Color Measurement:
●Using the HP Printer Utility for Windows, select Color Center > Paper Preset Management >
Color Measurement.
●Using the HP Printer Utility for Mac OS, select HP Color Center > Paper Preset Management.
Select the paper type, then press the 
 button and select Color Measurement from the popup
menu.
Continue with the following steps.
1.Choose the workflow that you want to use from the following options:
●Print and measure a color chart performs printing and measurement in a single process.
You can choose whether to use gloss enhancer and how much drying time to allow.
●Print a color chart for later measurement assumes that you will measure the printed chart
at some later time to complete the process. You can choose whether to use gloss enhancer.
●Measure a previously printed color chart completes the process if you have a color chart
ready for measurement. Load the chart in the correct direction as indicated by the arrows,
loading multiple pages in the correct order, and do not cut the paper.
●Export a color chart as a TIFF for printing externally allows you to use a different program
(a RIP, for example) to print the color chart. Do not modify the TIFF file in any way before
printing it. The printed chart should be exactly the correct size; the simplest way to achieve
this is to print it on a paper size larger than the chart and then cut the paper after printing as
indicated by the crop marks.
2.If printing a chart, select one of the available charts.
3.If measuring a chart, select the characteristics of the measurements file: what sort of information
it should contain (CGATS and MonacoPROFILER formats are supported), and where the file
should be saved.
NOTE:Chart measurement may not be successful if you load the chart as a single sheet without
skew check.
4.Open the measurements file with your profiling program.

							NOTE:The printers spectrophotometer measures from 400 to 700 nm in steps of 20 nm. All other
measurement types are interpolated.
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.
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. The details
of this process depend on the graphics language that you are using.
◦PostScript: the PostScript interpreter module inside the printer performs the color conversion
using the profiles stored in the printer (including those generated by the HP Color Center) and
any additional profiles sent with the PostScript job. This kind of color management is done
when you are using the PostScript driver and you specify printer color management or when
you send a PostScript, PDF, TIFF or JPEG file directly to the printer through the Embedded
Web Server. In either case you have to select the profiles to use as default (in case the job
doesnt specify any) and the rendering intent to apply.
◦Non-PostScript (PCL3): the color management is done using a set of stored ICC profiles.
This method is somewhat less versatile than the previous methods, but is a little simpler and
faster, and can produce good results with standard HP paper types. This kind of color
management is done when you are using a non-PostScript driver and you specify printer color
management, or when you send a PCL3 file directly to the printer through the Embedded Web
Server.
There are only two color spaces that the printer can convert to its own color space using the
stored profiles: Adobe RGB and sRGB if you are using Windows, Adobe RGB if you are using
Mac OS. In addition, you can use ColorSync.
ColorSync is the Mac OS built-in Color Management System; so, when you select ColorSync,
color management is performed by Mac OS, and it is done based on the ICC profiles of the
specified paper type. ColorSync is available with the PCL3 driver only.
ColorSync can be selected under Mac OS X 10.4 from the Paper Type/Quality panel: select
the Color tab, then select Use Embedded (ICC/ColorSync) from the Source Profile drop-
down list. Under Mac OS X 10.5, ColorSync can be selected from the Color Matching panel.
You are recommended to consult the Knowledge Center at 
http://www.hp.com/go/z3200ps/
knowledgecenter/ to see how to use the color management options of your particular application.
ENWW Color management options 73
Color management
 
						

							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 (PCL3 driver): go to the Paper Type/Quality panel and select
Color.
●In the Mac OS Print dialog (PostScript driver): select the Color Options panel.
●In some applications: you can make this choice in the application.
Color management example with Photoshop
In this example, you have an Adobe RGB image that you want to print from Photoshop. There are three
ways of doing it.
●Select Let Photoshop determine colors in Photoshop. Select Application-Managed Colors in
the printer driver. Color management is done in Photoshop. This is the recommended way.
●Select Let printer determine colors in Photoshop. Select Printer-Managed Colors and the sRGB
profile in the printer driver. Photoshop converts the image from Adobe RGB to sRGB and sends it
to the printer. Color management is done in the printer. Unfortunately, conversion to sRGB results
in a loss of gamut, but Photoshop cannot be prevented from converting to sRGB when Let printer
determine colors is selected.
●Select No color management in Photoshop. Select Printer-Managed Colors and the AdobeRGB
profile in the printer driver. Photoshop does not perform any conversion, there is no loss of gamut,
and color management is done in the printer. However, this method will not work if you are using
synchronized color management in Photoshop (see below).
Synchronized color management with Photoshop
If you are using Adobe Photoshop CS2 for Mac OS, or Adobe Photoshop CS3 for Windows, or later
versions, the color management options can be automatically synchronized between Photoshop and
the driver.
●If you select Let Photoshop determine colors or No color management in Photoshop,
Application-Managed Colors is automatically selected in the driver.
●If you select Let printer determine colors in Photoshop, Printer-Managed Colors is
automatically selected in the driver. The PostScript driver will use the color profile attached to the
job by Photoshop.
To enable this Photoshop synchronization under Windows XP, you must download and install the
following free software packages from Microsofts Web site:
●Microsoft Core XML Services (MSXML) 6.0
●Microsoft XML Paper Specification Essentials Pack 1.0
Perform black point compensation
NOTE:This option is available only when printing a PostScript or PDF job.
The black point compensation option controls whether to adjust for differences in black points when
converting colors between color spaces. When this option is selected, the full dynamic range of the
source space is mapped into the full dynamic range of the destination space. It can be very useful in
preserving shadows when the black point of the source space is darker than that of the destination
space. This option is allowed only when the relative colorimetric rendering intent is selected (see 
Set
the rendering intent on page 75).
74 Chapter 6   Color management ENWW
Color management
 
						

							Black point compensation can be specified in the following ways:
●On the Embedded Web Servers Submit Job page: select Color > Black point
compensation.
●
Using the front panel: select the Setup menu icon 
, then Printing preferences > Color >
Black point compensation.
Set the rendering intent
NOTE:This option is available only when printing a PostScript, PDF, TIFF or JPEG job.
Rendering intent is one of the settings used when doing a color transformation. As you probably know,
some of the colors you want to print may not be reproducible by the printer. The rendering intent allows
you to select one of four different ways of handling these so-called out-of-gamut colors.
●Saturation (graphics): best used for presentation graphics, charts, or images made up of bright,
saturated colors.
●Perceptual (images): best used for photographs or images in which colors blend together. It tries
to preserve the overall color appearance.
●Relative colorimetric (proofing): best used when you want to match a particular color. This
method is mainly used for proofing. It guarantees that, if a color can be printed accurately, it will
be printed accurately. The other methods will probably provide a more pleasing range of colors but
do not guarantee that any particular color will be printed accurately. It maps the white of the input
space to the white of the paper on which you are printing.
●Absolute colorimetric (proofing): the same as relative colorimetric, but without mapping the
white. This rendering is also used mainly for proofing, where the goal is to simulate the output of
one printer (including its white point).
The rendering intent can be specified in the following ways:
●On the Embedded Web Servers Submit Job page: select Color > Rendering intent.
●
Using the front panel: select the Setup menu icon 
, then Printing preferences > Color >
Select rendering intent.
Color emulation
Your printer can emulate the color behavior of other devices: RGB devices such as monitors, and CMYK
devices such as presses and printers.
NOTE:The printer performs these color emulations only if the job has no attached ICC profile. If the
job has an attached profile, it will be used instead of any color emulation.
You can set color emulation in the following ways:
●In the Windows driver dialog: select the Color tab, and Printer Managed Colors.
●In the Mac OS Print dialog: select the Color Options panel, and Printer Managed Colors.
●
Using the front panel: select the Setup menu icon 
, then Printing preferences > Color >
Select RGB source profile or Select CMYK source profile.
For a good emulation, the printer needs a specification of the colors these devices can reproduce. The
standard way of encapsulating such information is in ICC profiles. As part of the solution, we provide
ENWWSet the rendering intent 75
Color management
 
						

							the most common standards for the different devices. Apart from selecting the appropriate ICC profile,
you should select the appropriate rendering intent depending on the type of print: business presentation,
photography or proof. See 
Set the rendering intent on page 75.
The options are as follows.
CMYK color emulation
A traditional workflow defines color in the CMYK space. For best results, the colors must be adjusted
to the printer, because different printers will produce different colors from the same CMYK data. If the
image file you are printing was not created specifically for your HP Designjet printer, it will require some
readjustment, which can be done using one of the following options provided with your printer.
All CMYK emulation options apply to PDF, PostScript, TIFF and JPEG files only.
●None (Native): no emulation. The printer will use its default internal conversion from CMYK to
RGB, without following any color standard. This does not imply that results will be bad
●U.S. Sheetfed Coated 2 uses specifications designed to produce quality separations using U.S.
inks under the following printing conditions: 350% total area of ink coverage, negative plate, bright
white offset stock.
●U.S. Sheetfed Uncoated 2 uses specifications designed to produce quality separations using U.S.
inks under the following printing conditions: 260% total area of ink coverage, negative plate,

It is designed to produce quality separations using 310% total ink coverage, positive film and
uncoated paper.
●Japan Color 2002 Newspaper uses the Japan Color 2002 for Newspapers specification. It is
designed to produce quality separations using 240% total ink coverage, positive film and standard
newsprint paper.
●Japan Web Coated (Ad) uses specifications developed by the Japan Magazine Publisher
Association for digital proofing of images in the Japanese magazine/advertising market.
●Toyo is designed to produce quality separations for Toyo printing presses.

							NOTE:These options have no effect if the application is defining its own CMYK space, known as
calibrated CMYK or CIEBasedDEFG in PostScript terminology.
RGB color emulation
These options apply to PDF, PostScript, TIFF and JPEG files.
Your printer is provided with the following color profiles:
●None (Native): no emulation, for use when the color conversion is done by the application or
operating system, and therefore the data arrive at the printer already color-managed.
●sRGB IEC61966-2.1 emulates the characteristics of the average PC monitor. This standard space
is endorsed by many hardware and software manufacturers, and is becoming the default color
space for many scanners, printers and software applications.
●ColorMatch RGB emulates the native color space of Radius Pressview monitors. This space
provides a smaller gamut alternative to Adobe RGB (1998) for print production work.
●Apple RGB emulates the characteristics of the average Apple monitor, and is used by a variety of
desktop publishing applications. Use this space for files that you plan to display on Apple monitors,
or for working with old desktop publishing files.
●Adobe RGB (1998) provides a fairly large gamut of RGB colors. Use this space if you need to do
print production work with a broad range of colors.
HP Professional PANTONE Emulation
When you use a named PANTONE color in an image, your application will normally send to the printer
a CMYK or RGB approximation to that color. But the application does not take the printer or the paper
type into account, it merely produces a generic approximation of the PANTONE color, which will look
different on different printers and on different papers.
HP Professional PANTONE Emulation can do a much better job by taking into account the
characteristics of the printer and the paper type. The results look as similar to the original PANTONE
colors as is possible on a given printer using a given paper type. This technology is designed to produce
emulations similar to those set up manually by prepress professionals.
To use HP Professional PANTONE Emulation, all you have to do is to turn it on. In fact, it is normally
on by default.
●In the Windows PostScript driver dialog: go to the Color tab and select HP Professional
PANTONE Emulation.
●In the Mac OS Print dialog: go to the Color Options panel and select HP Professional
PANTONE Emulation.
●On the Embedded Web Servers Submit Job page: select Color > HP Professional PANTONE
Emulation.
NOTE:HP Professional PANTONE Emulation is available only when printing a PostScript or PDF job.
You can also use the Embedded Web Server to print a swatch book showing emulations of PANTONE
colors as made by your printer, together with a measure of the color difference (ΔE) between each
emulation and the original PANTONE spot color. So HP Professional PANTONE Emulation not only
provides the closest match that can be achieved on your printer; it also gives clear information on how
close the emulation is to the original spot color.
To print a swatch book, select the Embedded Web Servers Main tab, then HP Professional PANTONE
Emulation. Select the strips from different PANTONE Formula Guide tabs that you would like to print,

							then press the Next button. Check the strips that you have selected; select gloss enhancer if you want
to use it. Then press the Print button to print the swatch book.
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.
78 Chapter 6   Color management ENWW
Color management
 
						

							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 (PostScript driver): select the Color Options panel, then Lightness
and Hue.
●In the Mac OS Print dialog (PCL3 driver): 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 (PostScript driver): select the Color Options panel, then Gray
balance.
●In the Mac OS Print dialog (PCL3 driver): 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.
