You are recommended to consult the Knowledge Center at http://www.hp.com/go/Z5200ps/ knowledgecenter/ 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 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.

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.

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 70 Chapter 6 Color management ENWW

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 Microsoft's 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
