Clear laser coding

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.
