Stensborg has developed a new time- and cost-efficient process of producing holograms. This is how the Holoprint technology works

How does the Holoprint technology differ from the traditional holographic processes?

The technique of mass-producing holograms have existed since the 1980’s and various processes has been developed, mostly involving the use of a foil as a hot stamp foil or as a embossed label foil or a cold foil. Foil production is a very tedious process involving multiple production steps and handling multiple layers of materials. Most foils that need to be applied to a substrate also demands a metal layer to maintain the refractive index difference between the holographic structure and an adhesive.


Holoprint allows you to directly imprint a hologram onto your pre- or post printed web material completely without the use of a prefabricated foil and you can normally do 30.000 or more impressions before having to change imprint plates which we normally do in less than 5 minutes by just changing the imprinting cylinder.


As the hologram imprinting is done inhouse it makes it both more cost-efficient and more secure.


How does the Holoprint technology work?

The Holoprint unit consists of a resin applicator, typically a flexographic or digital unit that print discrete areas with light curing resin and an imprinting unit – the Holoprinter – which imprint the holographic nano surface relief structure in register spot imprinting. You only print light curing resin in the spot where you imprint the hologram. This saves you a lot of resin compared to traditional hologram production.


The light curing resin enters the Holoprinter where a nip is created between the imprint roller and a counter pressure roller and a 3. step sequence takes place. See illustration below.


  1. Resin enters the imprint plates.
  2. The resin is cured when light from the optical engine enters the resin through the imprint roller and the imprint plate.
  3. The hardened resin is deformed from the imprint plate and the hologram or any other nano sized 3D pattering is now imprinted and cured in the hardened resin and is now ready for any further printing steps required. By nature the holographic profile is open and even it is maintained in a robust resin you’re free to choose various steps to further protect the holographic grating with a high refractive index protection, if this is required from the end application.
