A graphic overlay, also known as a nameplate, is a printed graphic surface placed over the internal electronics of a product. It serves multiple functions, primarily protecting sensitive materials and components from environmental conditions and wear.
Graphic overlays are widely used in various fields, including electronic communication, electronic measuring instruments, industrial control, medical equipment, the automotive industry, smart toys, household appliances, and more.
