ISCENT's new Holo-like optical material.

A new Finnish company, ISCENT OY, has introduced a printable 'holographic-like' film technology for plastic-based and fibre-based packages, which was developed by the Technical Research Centre of Finland (VTT).

It also claims that it is a more environmentally sensitive method of producing these effects than using holograms as no additional material is needed - there is no metallizing, no lacquers or lamination required.

Since 2008 VTT has been developing this …
