Abstract

An apparatus for UV marking a substrate comprises: an ink jet apparatus having UV sensitive ink, the ink jet apparatus being configured to eject the UV sensitive ink; and an extruder producing a wire and insulation in a processing direction. The ink jet apparatus is configured in relation to the processing direction so as to eject UV sensitive ink in a pattern onto a surface of the wire and insulation. Additionally, an apparatus for forming a UV marked product comprises: first and second injection devices; and a two layer mold injection unit at the output of the first and second injection devices. The first injection device uses a first mixture of a polymer, a color masterbatch, and a UV sensitive masterbatch, and the second injection device uses a second mixture of the polymer and the color masterbatch, and the first mixture and the second mixture are injected into the two layer mold to form a UV marked product having a UV sensitive section and a non-UV sensitive section. Further, methods related to UV marked or formed products and methods for recognizing legitimate products marked by the marking methods.
