Barrier coat
Labels or self-adhesive materials must have a
barrier coat on the side to be printed which pro-
vides reliable protection against the adhesive or
its solvent from being released.
Elasticity
The printing substrate must pass over rollers
and change directions several times, but with-
out being permanently deformed and causing
blisters and creases to form. Labels should not
come loose from their respective backing mate-
rial during this process.
Taped seams
Each roll of printing substrate that is delivered
should consist of one single length of uninter-
rupted material preferably. If this is not possible
for technical reasons, the separate sections
should be joined to one another using heat-
resistant, highly visible tape so that these
seams cannot get into the print head unit or the
primary UV curing unit during the printing pro-
cess.
Heat resistance
The temperatures beneath the print head units
can reach levels of up to 50°C. In the main cur-
ing unit the printing substrate is subjected to
even higher temperatures which can reach
100°C under particularly unfavorable condi-
tions. Besides the printing speed, the greatest
determining factor with regard to heat genera-
tion is the appearance of the print image in
question, since the more dark colors it contains,
the more light will be absorbed and converted
into heat, which the printing substrate might
only be able to release slowly into the environ-
ment.
IMPORTANT !
The printing material must be able to withstand
these high temperatures for several minutes at
a time without softening significantly, because it
is kept under constant tension and could tear
otherwise. If the material tears, it could come
into contact with the print head and, in the worst
case scenario, cause irreparable damage! Fur-
thermore, the printing material should not emit
any vapors or, especially, decompose when
subjected to heat!
When selecting a printing substrate to use, make sure that it fulfills as many
of the following criteria as possible.
