The Technology

With a growing demand for hologram printing for increased security and the existing hologram-printing technology out-of-date and cumbersome, Stensborg spotted a glaring gap in the market and developed Holoprint®, the world’s first in-line hologram production process.

Our custom-made Holoprint machines integrate nanoimprints directly in the printing process, so you can imprint 3D nanostructured patterns such as holograms onto pre or post-printed web material without the use of prefabricated foils. At least 30,000 impressions can be produced before imprint plates need to be changed.

How does the Holoprint technology work?

Our unique, cutting-edge technology also provides you with:

 

  • Super-sharp structure definition

  • The ability to print on almost any surface – flexible or solid, transparent or opaque

  • Optimised UV lacquers for 20 nm to 100 micron feature sizes

  • Long run polymer printing plates

 

Using nanometer scale relief structured templates, light-curing resin and UV light, you can make nanoimprints on almost any surface. The nanoimprint is made when the curing light hits the nanostructured imprint plate and hardens the light-curing resin that has been applied to the selected areas of the material.

The Process

 
  • The light-curing resin enters the Holoprinter and a nip is created between the imprint roller and a counter pressure roller.

  • The resin is cured when light from the optical engine enters it via the imprint roller and the imprint plate.

  • The hardened resin is removed from the imprint plate and the hologram or any other nano-sized 3D pattern is now imprinted and cured in the hardened resin, ready for any further printing.

  • At this point, you can choose to:

    • protect the holographic grating with a high refractive index protection

    • use an inline or off-line metalizing step

    • use in-register lamination with airgap

    • use as is (this is the most cost efficient option)

 

The Holoprint unit is made up of a resin applicator that applies the light-curing resin, with precision, to your chosen area. Plus, of course, the imprinting unit that sends curing light through a transparent transfer roller: the Holoprinter.
