●Leave the printer permanently turned on so that it can maintain the printhead in good condition automatically. This regular printhead maintenance uses a small amount of ink. However, if it is not done, the printer may need to use much more ink later to restore the health of the printhead.

●Wide prints make more efficient use of ink than narrow prints, because printhead maintenance uses some ink, and its frequency is related to the number of passes made by the printhead.

Color management

Your printer has been engineered with advanced hardware and software features to ensure predictable and dependable color results.

●State-of-the-art HP printheads and HP inks

●Dedicated color resources for most available paper types

●Color emulation of other HP Designjet printers

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. Color management is highly dependent on the paper type loaded at the printer, so please select the correct preset for the paper type you are using.

The color management options for your printer can be selected from the Color menu in the Windows driver dialog or from the Color Options panel in the Mac OS X Print dialog. In some applications you can make the choice in the application itself. Please consult the HP Support Center for guidance on how to use the color management options of your particular application.

●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 color management in the printer is done using a set of stored color tables. ICC profiles are not used. This method can produce very good results with supported HP paper types. There are two color spaces that the printer can convert to its own color space using the stored color tables: sRGB and Adobe RGB.

◦sRGB emulates the characteristics of the average computer monitor. This standard space is endorsed by many hardware and software manufacturers, and has become the default color space for many scanners, cameras, printers, and software applications.

◦Adobe RGB provides a larger color gamut than sRGB. Use this space if you need to do print production work with a wide range of colors.

Printer emulation

If you want to print a particular job and to see approximately the same colors that you would get from printing the same job on a different HP Designjet printer, you can use the emulation mode provided by your printer.

NOTE: Printer emulation is available only when printing an HP-GL/2 job on plain or coated paper. It is not available from Mac OS X.
