Setting Explanation If too low If too high
Warm-up
drying
temperature
offset
Offset added to the drying temperature (see
main settings). Their sum determines the
effective surface temperature that the
substrate in the print zone must reach before
printing starts. This sum value is displayed in
the printer front panel while the printer is
preparing to start printing. Once it is achieved,
the printing job specific settings values are
then displayed and used.
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
The temperature that the substrate in the
curing zone must reach before printing starts.
N/A – Determined
by printer
firmware.

Offset added to the warm-up curing
temperature. Their sum determines the

substrate in the curing zone must reach
before printing starts. This sum value is
displayed in the printer front panel while the
printer is preparing to start printing. Once it is
achieved, the printing job specific settings
values are then displayed and used.
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
The temperature that the substrate in the
print zone must reach before the substrate
stops moving.
N/A – Determined
by printer
firmware.
N/A – Determined by
printer firmware.
Cool-down
drying
temperature
offset
Offset added to the cool-down drying
temperature. Their sum determines the
effective safe surface temperature at which
the substrate can be under the drying module
without being damaged. At the end of a job,
the substrate does not stop moving 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 a too-
high temperature. This
case is uncommon.

The end of the print
may be damaged if the
cutter is disabled.
