You can also use the Embedded Web Server to print a swatch book showing emulations of PANTONE
colors as made by your printer, together with a measure of the color difference (ΔE) between each
emulation and the original PANTONE spot color. So HP Professional PANTONE Emulation not only
provides the closest match that can be achieved on your printer; it also gives clear information on how
close the emulation is to the original spot color. See Printing PANTONE swatch books (T1300 PS)
on page 95 .
Color emulation
Your printer can emulate the color behavior of other devices: RGB devices such as monitors, and
CMYK devices such as presses and printers.
You can set color emulation in the following ways:
● In the Windows PostScript driver dialog: select the Color tab, and Printer Managed
Colors.
● In the Mac OS Print dialog: select the Color Options panel, then select Printer from the
Color Management list.
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.
The options are as follows.
CMYK color emulation
A traditional workflow defines color in the CMYK space. For best results, the colors must be adjusted to
the printer, because different printers will produce different colors from the same CMYK data. If the
image file you are printing was not created specifically for your printer, it will require some
readjustment, which can be done using one of the following options provided with your printer.
● None (Native): no emulation. The printer will use its default internal conversion from CMYK to
RGB, without following any color standard. This does not imply that results will be bad
● ISO Coated 2-ECI is based on the characterization dataset FOGRA39L.txt, applicable to the
