1. A method for producing a 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 optionally preprinted with security print, and (ii) a porous opaque receiving layer comprising a pigment and a binder, (2) printing digitally stored information on said porous receiving layer, (3) applying on top of said layer in a predetermined pattern a curable varnish, by means of printing, spraying or jetting, (4) curing said applied varnish, whereby the parts of the receiving layer under said predetermined pattern remain non-transparent, (5) overall covering the thus obtained assemblage by coating, printing, spraying or jetting, with a curable lacquer whereby said lacquer penetrates all areas of the receiving layer not covered by the pattern of the varnish and renders them substantially transparent, and whereby the non-transparent pattern obtained by application of the varnish forms a substantially opaque watermark, (6) subjecting the thus obtained assemblage to a second curing step.
