Substrate specifications
Depending on the technical equipment involved, every ITS6 printer is ca-
pable of printing a host of materials, be it labels or continuous webs of met-
al foil, paper, plastic or even textiles. All of them must fulfill the following cri-
teria:
Requirement
Reason
Good wettability
The ink should not roll off after it is applied, but
rather should be held firm in place until the last
curing process is completed.
In some cases a more suitable printing sub-
strate has to be used or else the printer in
question has to be equipped with corona treat-
ment.
Mechanical resilience The printing substrate is conveyed through the
printer at high speed and under high tensile
stress while changing directions several times.
Perforated or pre-cut printing material has poor
tear resistance and, therefore, is generally not
permitted for use in the ITS6 printer.
Surface and material
properties
The printing substrate should have a homoge-
nous structure, a smooth, blister-free surface
and straight edges.
The surfaces of the material to be printed
– this
includes the end faces of the roll of printing
material
– must be free of any loose particles,
dust or sticky substances (e.g. gelatin), since
these could damage the print heads directly or
greatly impair the effectiveness of the printing
substrate cleaning module.
Thick fibers in textile materials should lie in the
direction of travel whenever possible. Likewise,
fibers should not protrude from the fabric, since
they could get caught in the nozzles of the print
heads and clog them permanently.
No distortion ("center
bowing")
The printing substrate is not to become de-
formed (center bowing or wavy edges) at all or
only by 0.2 mm during the moisture equaliza-
tion process since the edges of the printing
substrate could otherwise rub along the sensi-
tive nozzle plates of the print heads and may
clog or damage these.
Chemical resistance
Neither the printing substrate itself nor any
coating it might have should be able to be dis-
solved or chemically altered by the ink or clean-
ing fluid used. The same applies to the backing
material of labels.
