In tunnel building, it is only the careful sealing of all joints between the concrete segments which prevents the penetration of water and potentially harmful substances. Innovative rubber profiles are also the basis for comfort and operational safety in railway track construction. In applications such as these, the demands placed on product markings are no less strict than those addressing the material used.
The information markings on construction materials initially serve to simplify handling and use on the construction site. But also after many years of use, perhaps under extreme conditions, they provide for reliable traceability. Even the standard inks used in the continuous inkjet coding systems of the alphaJET series can be characterized by their outstanding adhesion properties. They are furthermore complemented with an extensive range of special inks.
