Color Calibration
The Color Calibration should ONLY be performed by the user
when required.
Why calibrate color?
Calibrate color perf
orms a maintenance function to ensure color
consistency. If you calibrate correctly, the colors printed on printers with
different printheads will look very similar.
When do I calibrate color?
It is recommended that you cali
brate color every time you replace a
printhead or when you perceive color degradation on the printouts. There is
no need to perform this operation each time you print. The results of the
color calibration will be applied to all print jobs that follow, even if you
power off the printer.
Perform color calibration if you print with the regular hp designjet 120
pr
inter driver, which was included with the printer or which you downloaded
from the Web. If you use a PostScript driver such as Adobe PS or LaserWriter
to print through a PostScript RIP provided by HP or another third-party
company, the results of calibrate color will not be applied to your print
jobs. In this case, refer to your PostScript RIP documentation for information
on how to perform color calibration.
How do I calibrate color?
You have to ca
lib
rate color for every Paper Type that requires color
consistency. For example, if you require consistent colors on glossy paper
and on heavy weight coated paper, you must perform one color calibration
for the former and another for the latter Paper Type.
When you want to calibrate color, remember to select the Print Quality
opti
on that you are going to use to print. For example, if you want to print
with the High Resolution option, select High Resolution before performing the
color calibration.
If the Color calibration fails, print the information page and
c
h
eck the list of warnings under the printer status section.

could look like before and after color calibration.
