Abstract

A method for the manufacturing of a tamper proof carrier of information is disclosed comprising a support and an opaque porous ink receiving layer. The carrier comprises at least two sets of information, preferably a first set representing general information or security print, and a second set representing personalized information. The ink receiving layer is rendered transparent by impregnation with a UV curable lacquer whereby the underlying information is revealed. Upon UV curing its mechanical properties are improved. The finished information carrier is preferably cut in a set of multiple identification cards.
