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). Perform black point compensation 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 Rendering intent on page 112). Color management from the front panel You can color-calibrate the loaded paper type from the front panel by pressing , then Image quality maintenance > Calibrate color. See Color calibration on page 104. , then The other color options in the front panel can all be found by pressing Printing preferences > Color options. , then , then Setup > NOTE: These front panel settings can all be overridden by the printer driver or Embedded Web Server job submission settings. ● Color/Grayscale: you can choose to print in color, in shades of gray, or in black and white. Default: Print in color. ● Select RGB source profile: you can choose from a selection of RGB source profiles recognized by the printer. Default: sRGB. ● Emulate printer: you can choose to emulate a different HP DesignJet printer. Default: Off (no printer emulation). TIP: If you have old HP-GL/2 or PostScript files made for a different HP DesignJet printer, you can send them to the printer and use the front panel to turn on the appropriate emulation mode.

Default: US Coated SWOP v2. ● Select rendering intent: you can select the rendering intent. Default: Perceptual. ● Black point compensation: you can turn black point compensation on or off. Default: On. ● HP Professional PANTONE Emulation: you can turn HP Professional PANTONE Emulation on or off. Default: On. Color management and the scanner The files obtained from your scanner (TIFF, JPEG, PDF) contain an embedded ICC profile corresponding to the type of paper selected prior to making the scan.
