Single-Layer Encoded

Single-layer encoded holograms utilize Moiré Fringe technology to encrypt information onto the hologram master, enhancing the security features of the holographic design.

Moiré fringes are interference patterns that emerge when two patterned surfaces overlap. These fringes manifest when two sets of parallel stripes, alternating between dark and light, or two periodic patterns, are superimposed with a slight angle of misalignment.

Encrypted information in single-layer encoded holograms remains undetectable to the naked eye, magnifying glass, microscope, and ultraviolet light, contributing to enhanced security features.

In the market, two common designs for single-layer encoded holograms are Covert and Overt. In Covert designs, hidden information is revealed only when a special validator/decoder is applied. Conversely, in Overt designs, information is openly displayed but disappears when a special validator/decoder is used.

Low quality, poorly designed encoded information, or using a mismatched decoder can result in blurry effects when the decoder is applied, compromising the effectiveness of the security feature.

• Small Order Quantity
• Short Production Lead Time
• Extra Layer of Security
• Enhance Product Image

To address the potential reproduction challenges of a normal single layer of encoded information by a professional hologram manufacturer, the solution is to adopt Multi-Layer Encoded Image or Text technology, which enhances the complexity and security of the holographic design.

A sophisticated solution involves employing the demetallization technique and encoding the numbering directly on the foil. This ensures that the encoded number on each label is unique, contributing to enhanced security.
