Interferential varnishes for printing
Interferential varnishes are transparent varnishes which shine and shimmer with different colours, depending on a viewing angle.
They come in a variety of shades, from varnishes changing in two colours to the ones that change many colours like a chameleon.
Interferential varnishes are used for refinement of luxurious packagings of alcohols, cosmetics, pharmaceutical products.
They are also used in protecting documents and securities from forgery and copying.
The thicker the varnish layer, the better the interferential effect.
