Postage Stamps with Holograms

The integration of holography with postage stamps represents one of the more unusual intersections between security printing, applied optics and philately. The new edition of ‘Holography and Philately: Postage Stamps with Holograms’ marks the most authoritative consolidation of this specialised field to date and underscores how innovation in hologram stamps has ebbed and flowed in recent years.

Holography Exhibitions from the 1980s to Gallery 286

Display holography has always been as much about how it is shown as how it is made. Unlike photography or print, a hologram can’t simply be hung on a wall, leaving the lighting to chance. It must be illuminated, angled and viewed under carefully controlled conditions to reconstruct the recorded wavefront. These physical constraints make the exhibiting of holography as much to do with where it is being shown as it is about what is being shown.

Understanding the WOW Factor in Security Holography

As part of an initiative to define and categorise the visual characteristics that contribute to the ‘WOW factor’ in security holography, Reconnaissance International conducted a global survey of professionals involved in the specification, design, and assessment of holographic security features. The objective was to identify the attributes that are most effective in capturing attention and supporting document authentication across both ID documents and banknotes.

When Holograms Disappoint

It used to be that poor lighting was the major cause of disappointment when it came to viewing holograms. But as the definition of holography has been stretched to include heightened reality displays, so have the number of reasons to be disappointed.

What’s in a Name?

The use of the term ‘holography’ to describe phenomena other than wavefront reconstruction is now well established in the media. Often, the purpose of using the term is to convey a sense of futuristic heightened reality, which can be frustrating to holography purists but could also be seen as praise if you believe the idiom ‘imitation is the sincerest form of flattery’.
