A variety of materials such as Steel, Aluminium, Plastic & Composites are processed and shipped to different customer locations. The processed items are in many forms like cylinders, sheets, coils, box, cans, slabs & rods; the dimensions can vary from millimeters to meters. To prevent product mix-up and to ensure internal traceability, there is a need for an invisible marking, that cannot be detected by human eye. The marking has to be durable so that it cannot be inadvertently rubbed off, scratched or removed, all the while providing us with a unique means for tracing the products. We should be able to apply the markings inline during processing or manufacturing on a variety of substrates of Steel, Aluminium, Plastics, and Composites. The marking should be unaffected during various processing steps, viz. cutting/slitting, thickness reduction, and surface cleaning to remove impurities like rust, dirt, and oil.
Desired properties of the marking:
The solver will be awarded only upon successful demonstration of Proof of Concept (PoC).
