Description
If too low
If too high
Passes The number of passes specifies
how many times the printheads
will print over the same area of
the substrate.
The amount of ink fired
per time unit is larger
and the ink has less
time to dry on the sub-
strate. This may create
coalescence and band-
ing. The boundaries
between passes may
be more visible. How-
ever, printing speed is
relatively high.
Colors are vivid, print quality is
high. However, printing speed is
relatively low. A lower curing
temperature is needed, other-
wise the substrate may become
deformed.
Curing temp. Curing is needed for the latex to
coalesce, creating a polymeric
film which acts as a protective
layer, while at the same time re-
moves the remaining co-sol-
vents from the print. Curing is vi-
tal to ensure durability of printed
images.
The print may emerge
not fully polymerized,
so that the ink smears
when rubbed. The print
may appear wet, after
printing or later. You
may need to increase
the number of passes
to achieve adequate
curing.
The substrate may wrinkle un-
der the curing module, causing
defects such as blisters or liner
detachment. The substrate
wrinkles may also cause vertical
banding or ink smears at the
beginning of the following plot.
Airflow Airflow helps to remove the
evaporated water from the print
zone and thus allows more effi-
cient drying.
In general, use the substrate family default value.
Substrate advance
compensation
Your printer was calibrated at
the factory to ensure that it ad-
vances the substrate accurately
when using supported sub-
strates 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 horizon-
tal banding or graini-
ness.
You may see horizontal banding
or graininess.
Input tension
Tension is applied to the sub-
strate from the input spindle. It
needs to be consistent over the
full width of the substrate, thus
substrate load is a critical opera-
tion.
The substrate skews
and may become in-
creasingly wrinkled in
the printing zone.
Also, substrate ad-
vance may be irregu-
lar, resulting in hori-
zontal banding.
The substrate may be perma-
nently deformed or damaged.
Substrate-advance problems
may appear in extreme cases.
Vacuum The vacuum applied to the sub-
strate at the printing zone helps
to hold the substrate down on
the print platen, keeping the dis-
tance to the printheads con-
sistent.
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 the sub-
strate advance irregular, result-
ing in horizontal banding or ir-
regular grainy patches.
