Marking of defective area
MRP offers marking devices with frontal movable print heads for the marking of the product web. On request, different colours, water-based or with solvents of fluorescent, can be used. Up to 3 print heads can be installed side by side. In order to detect system errors as soon as possible, a read back is performed di-rectly after label printing. The applied colour strips can be visually evaluated by the operator or a corresponding sensor located at the subsequent processing machines.
