HP DesignJet T790 and T1300 Printer Series - Using your printer

●
Relative colorimetric (proong): best used when you want to match a particular color. This method is mainly
used for proong. 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 (proong): the same as relative colorimetric, but without mapping the white. This
rendering is also used mainly for proong, 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 dierences 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 77).
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 dierence (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.
Color management from the front panel
