Create a new substrate preset
Whenever you load a new substrate type into your printer, you must choose a substrate preset for it.
1.
If possible, select a preset for the specific substrate type that you intend to load.
2.
If no specific preset is available, select a generic preset that corresponds to the specific type that
you intend to load. You may be able to get better results by creating a specific preset for your
substrate type.
3.
If no specific nor generic preset matches your substrate, select whatever preset seems to resemble
it most closely. You will probably get better results by creating a specific preset for your substrate
type.
Creating a new preset has several purposes.
●
You can assign a name of your own choice to a particular substrate.
●
You can adjust the preset to suit the precise characteristics of your substrate.
●
You can adjust the preset to your intended use of the substrate, which may range from highest-
quality printing to fast production output.
NOTE:
You can change only the presets that you have created yourself. The presets supplied by HP
cannot be changed.
Before creating a new preset, it is useful to understand a little about how the printer works. Here are
some of the available settings.
