HP Designjet T790 1118 mm User Manual

If nesting is turned on, the prioritized job may still be nested with others. If you really want this job to
be printed next, and not nested with others, first turn nesting off and then move it to the front of the
queue as described above.
Delete a job from the queue
Under normal circumstances, there is no need to delete a job from the queue after printing it, as it will
just fall off the end of the queue as more files are sent. However, if you have sent a file in error, and
want to avoid printing it,...

How colors are represented
All devices that display color use a color model to represent color in numerical terms. Most monitors
use the...

You can check the color calibration status of the currently loaded paper at any time by pressing 
and then  on the front panel. The status may be one of the following:
●Recommended: the paper has not been calibrated.
NOTE:Whenever you update the printers firmware, the color calibration status of all papers is
reset to Recommended.

Color management from printer drivers
Color management options
The aim of color management is to reproduce colors as accurately as possible on all devices: so that,
when you print an image, you see very similar colors as when you view the same image on your
monitor.
There are two basic approaches to color management for your printer:
●Application-Managed Colors: in this case your application program must convert the colors
of your image to the color space of your printer and paper type, using the ICC...

Printer emulation
If you want to print a particular job and to see approximately the same colors that you would get from
printing the same job on a different HP Designjet printer, you can use the emulation mode provided by
your printer.
NOTE:This option is available only when printing an HP-GL/2, PostScript or PDF job. It will work
correctly only when printing on plain, coated or heavyweight coated paper.
●In the Windows HP-GL/2 or PostScript driver dialog: select the Color tab, then Printer

●The lightness slider simply makes the whole print lighter or darker.
●The color sliders can be used to fade or emphasize each of the primary colors in the print. The
primary colors may be red, green and blue; or cyan, magenta and yellow; depending on the
color model used in the image.
The Reset button restores each slider to its default central position.
Printing in grayscale
You can convert all colors in your image to shades of gray in the following ways:
●In your application program: many programs...

●The lightness slider simply makes the whole print lighter or darker. This slider is available in the
same window as the other grayscale controls.
●The zone definition sliders can be used to define what you mean by highlight, midtone and
shadow.
●The other controls for highlight, midtone and shadow can be used to adjust the gray balance of
highlights, midtones and shadows respectively.
The Reset button restores each control to its default setting.

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.
