Security inks
and Anti Tampering Packaging Technologies

With more and more products being orders online and delivered to doorsteps, criminals find new methods for fraud and theft. Whether it’s detecting clever counterfeits or thwarting the opening of packages to steal contents, CTI has developed several technologies designed to authenticate products or show tampering has occurred. See sections below for types and applications.

Advantages:

  • Covert and overt technologies, depending on requirements

  • Technologies may be combined to create a unique security feature

  • Printable technology, just like other high speed commercial inks

  • Full control over brand identity, graphic design and placement, either through existing printed label or direct package/container printing

  • Customizable with high-volume implementations

  • Long-term chemical stability

  • Safe for indirect food contact

  • BPA-, BPF-, BPS-free and compliant with REACH, Prop 65, CONEG, and many other regulations.

Invisible Ink Using Fluorescing

Just like most U.S. paper currency has invisible stripes that fluoresce specific colors when excited by blacklight (UVA wavelengths), your customers can add graphics or text printed in invisible ink to ensure authenticity. Fluorescing strength varies with printed ink film weight. See the difference between fluorescing and phosphorescent inks here.

Touch-Activated Thermochromic Security Inks

Touching or rubbing materials printed with this technology to generate warmth will make the color disappear or change to a lighter color (in the case of color-to-color inks), signaling at a glance the authenticity of a document or product. In ink formats that offer heavier film weights, such as UV Screen and UV Flexo, hide-and-reveal graphics are possible. Touch-activated security features offer simple and cost-effective solutions.

PhotoTag Security Ink Confirms Authentic or Fraudulent Packaging Through Ink

PhotoTag
Anti Tampering Packaging Technology

The ultimate in security, CTI’s PhotoTag anti tampering packaging technology makes it nearly impossible for criminals to side-step or counterfeit. The ink itself contains taggants that have a specific Raman signal profile that may be read and confirmed with a handheld device. Criminals would have to have not only the taggant material but would also have to program the device for that particular Raman signal.

 

Generally, government agencies and makers of high-value products use PhotoTag.

 

Each PhotoTag application requires an extensive understanding of the application, requirements, and qualification planning. Several ink formats are available. Contact CTI to learn more.

Pressure-Activated

See the description of pressure-activated inks, which may be used for security and tamper-evidence also.
