Linx Printing Technologies has
developed its Visicode technology
which is a central component of its
SL301 Scribing Laser coder. A change
in the pulse frequency encourages
the formation of micro cracks in the
top layer of cold glass to increase the
visibility of the mark.

The pulse frequency must also be
balanced against the marking speed
to produce the correct amount of
micro cracking. Linx says it can
produce the code with less power
than is usual for this type of task.

The SL301 is suitable for coding
different types of packaging and can
be customised as required. A blower
unit is required only for the optional
IP65-rated laser for environments
where washdown is critical.
