Carrier of information bearing a watermark |
(57) An information carrier comprising a support and a receiving layer is disclosed, together
with the method of preparation. The information carrier further comprises (optionally
personalized) information applied, preferably by ink jet printing, on the receiver
layer, and a new type of watermark, obtained by applying pattern-wise a curable varnish
and curing it, and by curing an overall applied curable lacquer. One of the varnish
and the lacquer have the ability upon penetration into the receiving layer of changing
its transparency, thus creating a transparent watermark on an opaque background, or
creating a opaque watermark on an transparent background. The finished information
carrier is preferably cut in a set of multiple identification (ID) cards.
