Color management from printer drivers
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 (PostScript printers): the PostScript interpreter module performs the color
conversion using the profiles stored in the printer 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 doesn't specify any) and the rendering
intent to apply.
◦
Non-PostScript (PCL, RTL, HP-GL/2): the color management is done using a set of
stored color tables. ICC profiles are not used. This method is somewhat less versatile than the
alternatives, 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 PCL, RTL or HP-GL/2
file directly to the printer through the Embedded Web Server.
NOTE: There 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, 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 PCL3GUI driver only.
ColorSync can be selected from the Color Matching panel.
You are recommended to consult the Knowledge Center (see Knowledge Center on page 201) 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.
