Substrate advance
compensation Your printer was calibrated at
the factory to ensure that it
advances the substrate
accurately when using supported
substrates in normal
environmental conditions.
However, you may find it useful
to adjust the substrate advance
when printing in an unusual but
stable temperature or humidity
level, or if the substrate-advance
sensor is not working. You may see horizontal banding
or grain. You may see horizontal banding
or grain.
Input tension Tension is applied to the
substrate from the input spindle.
It needs to be constant over the
full width of the substrate, thus
substrate load is a critical
operation. The substrate skews and may
become increasingly wrinkled in
the printing zone. Also, substrate
advance may be irregular,
resulting in horizontal banding. The substrate may be
permanently deformed or
damaged. Substrate advance
problems may appear in
extreme cases.
Vacuum The vacuum applied to the
substrate at the printing zone
helps to hold the substrate down
on the print platen, keeping the
distance to the printheads
constant. The substrate may lift up off the
platen and touch the printheads.
This can smear the printed
image, cause vertical banding,
cause a substrate jam or even
damage the printheads. For sticky substrates, friction
could be too high and substrate
advance irregular, resulting in
horizontal banding or irregular
grainy patches.
Bidirectional Specifies whether printheads
print in both directions, when
moving from left to right and
from right to left. If Bidirectional is selected, the
amount of ink fired per unit of
time is larger, and therefore print
quality defects such as
coalescence and banding may
occur, especially at the sides of
the plot. However, printing
speed is high. If Bidirectional is unchecked then
the printing is unidirectional and
the speed is relatively low.
TIP: You are recommended to
keep Bidirectional selected in all
cases, increasing the number of
passes if necessary to avoid
coalescence and banding.
High ink level The maximum quantity of ink will
be laid on the substrate (the
High ink level option available
only when the number of passes
is 10 or more). The ink quantity
may be reduced by the RIP color
profile. If not selected, colors may look
washed-out. If selected, there can be excess
of ink and some problems
related to poor drying and
curing.
TIP: Select High ink level for
backlit and some textile
applications, or if you want high
color saturation.
