One clever way of producing VIN labels is being offered by Schreiner Label Tech (Livonia, MI). Rather than engraving the information, the system uses what the company has named its "Color Laser Film," which is said to have a patented structure such that an Nd:YAG laser inscribes the required information onto the material in such a way that it is actually under a protective laminate surface. This subsurface marking is said to be durable and impossible to copy. What's more, it is said to be emissions-free during marking. The material also lends itself to putting in invisible features to help prevent counterfeiting.
