Rendering intent
Rendering intent is one of the settings used when doing a color transformation. As you probably know,
some of the colors you want to print may not be reproducible by the printer. The rendering intent allows
you to select one of four different ways of handling these so-called out-of-gamut colors.
● Saturation (graphics): best used for presentation graphics, charts or images made up of
bright, saturated colors.
● Perceptual (images): best used for photographs or images in which colors blend together. It
tries to preserve the overall color appearance.
● Relative colorimetric (proofing): best used when you want to match a particular color. This
method is mainly used for proofing. It guarantees that, if a color can be printed accurately, it will
be printed accurately. The other methods will probably provide a more pleasing range of colors
but do not 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 95 ).
Printing PANTONE swatch books (T1300 PS)
You can use the Embedded Web Server or the HP Utility 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.
To print a swatch book, select the Embedded Web Server's Main tab, then HP Professional
PANTONE Emulation. Select the PANTONE stock to emulate, and one or more strips of PANTONE
colors that you want to print. You can select color strips from more than one PANTONE stock. When
you have selected all the colors you want, press the Next button. The next window displays your
selection; you can press Print to print that selection, or Back to change the selection.
