HP Latex 360 Printer - Manual (Page 103)

If you delete a preset, you will lose the reference to that substrate in the usage and accounting information.
Instead of the name of the substrate, from that moment on you will see “Deleted substrate” in the usage and
accounting information.
Faster printing
The obvious way to increase speed is to reduce the number of print passes, although this will tend to reduce
print quality. Bear in mind the following considerations.
● With fewer than 8 passes, you may see an increase in grain.
● With fewer than 6 passes, the printer is more sensitive to substrate-advance problems, and you may
need to reduce the ink quantity to improve print quality.
● As you reduce the number of passes, the best curing temperature may be more difficult to find, and may
be more sensitive to the ambient temperature and humidity.
Here are some other suggestions for increasing the speed of printing.
● Concatenating prints saves time, because one can be printed while another is being cured.
●
Disable the cutter (360 only): press , then Substrate handling options > Cutter > Off. With
most substrates, this saves some time at the end of the printing process.
NOTE: Printing a single job for more than 2 hours can reduce the life of the printheads.

Color calibration
The purpose of color calibration is to produce consistent colors with the specific printheads, inks, and
substrate that you are using, and in your particular environmental conditions. After color calibration, you can
expect to get very similar prints from your printer on different occasions.
Each substrate must be calibrated independently.
NOTE: Color calibration may not work correctly with non-HP ink.
There are cases in which a substrate may not be calibrated, in which cases the Calibrate and Reset options
are not available:
● The loaded substrate has a generic preset.
● The loaded substrate has a preset that is not editable.
● The loaded substrate is not suitable for color calibration.
Color calibration can be launched from the front panel, after pressing Modify preset, or when adding a new
substrate.
In outline, the process consists of the following steps.
1. A calibration target is printed.
2. The colors on the calibration target are measured automatically.
3. The calibration target measurements are compared with an internal reference to calculate the
necessary calibration tables for consistent color printing on the substrate in use.
