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.

Dependent claims

A method for producing a tamper proof carrier of information, said method comprising the following steps, in order,

(1) providing a two-layer assemblage comprising (i) a rigid sheet or web support, and (ii) a porous opaque ink receiving layer comprising a pigment and a binder whereby either the surface of said support, or the surface of said opaque layer carries a first set of printed information,
(2) printing a second set of information, different from said first set, onto said porous opaque ink receiving layer by means of ink jet printing,
(3) covering totally, partially, or pattern-wise the thus obtained assemblage with a UV-curable laquer composition, by means of coating, printing, spraying or jetting, whereby on penetration of the lacquer in said porous opaque ink receiving layer this layer becomes substantially transparent,
(4) curing said lacquer composition by means of an overall UV exposure, thereby improving the adhesion between said support and said ink receiving layer, and the cohesive strength of said ink receiving layer.
