HP Professional PANTONE Emulation
When you use a named PANTONE color in an image, your application will normally send to the
printer a CMYK or RGB approximation to that color. But the application does not take the printer or the
paper type into account, it merely produces a generic approximation of the PANTONE color, which
will look different on different printers and on different papers.
HP Professional PANTONE Emulation can do a much better job by taking into account the
characteristics of the printer and the paper type. The results look as similar to the original PANTONE
colors as is possible on a given printer using a given paper type. This technology is designed to
produce emulations similar to those set up manually by prepress professionals.
To use HP Professional PANTONE Emulation, all you have to do is to turn it on. In fact, it is normally on
by default.
