The various settings mentioned above are described below.
Setting Description If too low If too high
Warm-up drying
temperature offset
The temperature that the
substrate in the print zone must
reach before printing starts.
Bleeding or coalescence may
appear in the first 200-300 mm of
the print.
A longer time to start printing is
required. Vertical banding or ink
smears may occur.
Warm-up curing
temperature offset
The temperature that the
substrate in the curing zone must
reach before printing starts.
The beginning of the print is not
fully dry, or looks oily.
Substrate degradation (bubbles,
adhesive detachment) at the
beginning of the print.
Cool-down drying
temperature offset
The safe temperature at which
the substrate can be under the
drying module without being
damaged. At the end of a job, the
substrate is not stopped until this
temperature is reached.
A long time is needed to finish the
print.
The substrate at the beginning of
the next print may be damaged,
because it has stopped moving
under too high a temperature.
This case is uncommon.
Cool-down curing
temperature offset
The safe temperature at which
the substrate can be under the
curing module without being
damaged. At the end of a job, the
substrate is not stopped until this
temperature is reached.
A long time is needed to finish the
print.
The end of the print may be
damaged if the cutter is disabled.
Minimum drying
power
The minimum power applied in
the drying module while printing,
so the substrate does not cool
too much in lightly inked areas.
A heavily inked area that comes
after a lightly inked area will have
bleeding or coalescence defects.
The substrate is damaged in
blank or lightly inked areas of the
print, especially with a high
number of passes.
Select the number of passes
Increasing the number of passes will tend to improve the print quality but reduce the speed of printing.
