Schreiner PrinTrust is now using a new counterfeit protection feature for fast, automatic authentication of toll fee stickers by monitoring authorities. CarSecure specialty pigment is invisible to the human eye, but a reader can demonstrate its presence in the sticker through the windshield. The specialty pigment can be embedded in the label using various printing techniques without requiring any graphic design changes. The material is highly UV-resistant and durable. For additional tamper evidence of the label, other security features such as kiss-cuts or covert VOID messages may be integrated as well.
