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
Select the color emulation mode on page 69
If you have problems making your printer emulate another HP Designjet printer, see
between different HP Designjets on page 157
.
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
Set the rendering intent on page 69
. For reference information on the broader
aspects of color printing refer to:
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.
