UV Ink in Tamper Evident Labels

UV ink in tamper evident labels can be printed on the surface or in the sub surface message. If the message is printed on the surface, packaging integrity can be verified easily and quickly with the use of a black light.

Ultraviolet (UV) inks are used as a security feature within labels to add a high quality print for a specific message within the label.

UV ink is invisible to the naked eye and can only be seen with the use of a UV light or black light.

If the sub surface void message contains UV, it is a covert security feature which will help defeat counterfeiters and validate genuine products such as pharmaceuticals and other high value items.

UV ink offers several advantages for tamper evident labels, making them more secure and reliable. Here’s how:

  • Covert Security Feature: UV ink is invisible under normal light. Only under a UV light (black light) will the special message or image printed with UV ink become visible. This hidden element makes it difficult to tamper with the label without leaving a trace, as tampering would likely disrupt the UV ink design.

 

  • Detection of Tampering: Tamper evident labels often incorporate a void pattern that becomes visible upon removal. By including a UV element within the void pattern, tampering becomes even more evident. Even if the label itself isn’t physically damaged, the broken UV pattern under the black light will reveal tampering.

 

  • Counterfeit Deterrence: The unique properties of UV ink make it a challenge to counterfeit. Replicating the specific fluorescent response of UV ink under UV light is difficult, adding another layer of protection against fake products.

 

  • Simple Verification: Verifying a label’s authenticity with UV ink only requires a UV light, a common and inexpensive tool. This ease of use makes it practical to incorporate UV ink into security measures for various applications.

 

Overall, UV ink in tamper evident labels enhances security by offering covert identification, clear tampering indicators, and a strong defense against counterfeiting. The ease of verification with a UV light makes it a practical solution for various industries.
