Quite often in the industry, there is production that is classified as defective, or in other words, scrap. It also needs to be correctly marked to properly manage the flow of defective and good quality products. It is very important that defective products are not mixed with good quality products and that they do not reach the customer in any way. This problem can be easily solved by using defective product marking equipment. This equipment allows the use of various colors of ink (including red, green, yellow, blue, etc.) suitable for various surfaces: metal, aluminum, PVC, PE, wood, cardboard.
