The various settings mentioned above are described below.
Setting 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 ink has less
time to dry on the substrate. This
may create coalescence and
banding. The boundaries
between passes may be more
visible. However, printing speed
is relatively high Colors are vivid, print quality is
high. However, printing speed is
relatively low.
Drying temp.
The heat applied in the printing
zone removes water and fixes
the image to the substrate.
Print-quality defects such as
banding, bleeding and
coalescence may occur.
Thermal marks may be seen on
the substrate; they may appear
as vertical bands in some colors.
The substrate may wrinkle on the
platen, causing vertical banding,
ink smears or substrate jams.
Curing temp. Curing is needed to coalesce the
latex, creating a polymeric film
which acts as a protective layer,
while at the same time removing
the remaining co-solvents from
the print. Curing is vital to ensure
the durability of the printed
images. The print may emerge not fully
polymerized, so that the ink
smears when rubbed with a
finger. The print may appear wet,
after printing or later. The substrate may wrinkle under
the curing module, causing
defects such as bubbles or liner
detachment. The substrate
wrinkles may also cause vertical
banding or ink smears at the
beginning of the following plot.
Heating Airflow Airflow helps to remove the
evaporated water from the print
zone and thus allows more
efficient drying. In general use the substrate family default value.
