Tell me about color emulation modes
Your printer can emulate the color behavior of other devices: RGB devices such as
monitors, and CMYK devices such as presses and printers. See “How do I select the
color emulation mode?” on page 141.
If you have problems making your printer emulate another HP Designjet printer,
see“The problem is color matching between different HP Designjets” on page 199.
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 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 “How do I set the rendering intent?” on page 140. For reference

The options are as follows.
Note PDF and PostScript files can be used with PostScript printers only.
CMYK color emulation
All CMYK emulation options apply to PDF, PostScript, TIFF, and JPEG files only.
●
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.
● HP CMYK Plus: a set of HP proprietary re-rendering rules that will produce a
good result for most digital commercial printing jobs, by expanding the reduced
gamut of your press into the wider gamut of your printer.
