BOBST – Still Innovating After All These Years

Ever since surface relief replication became the preferred means of mass production for holography, hot-stamping foil has been a principal method of application – particularly for packaging and secure documents. The machines used to apply holograms at speed and in register are an integral part of the job’s final appearance. Swiss machinery manufacturer, BOBST, has been involved in providing hot-stamp presses to the holography industry for many years, and continues to innovate to this day.

NGC Introduces New Security Hologram with Unique QR Codes

Holograms have a long and successful history as a decorative enhancement on coins (see HN November 2022), where, for example, a holographic relief structure is embossed into a resin that coats one side of the coin. But another range of coin applications for holography comes in the shape of security labels that demonstrate the authenticity of the coin.
