Abstract: There is described process for producing security papers, in particular banknotes, comprising the step of sealing the surface of the security papers by applying a protective pattern on the surface of the security paper, which sealing comprising printing the security papers by intaglio printing using an intaglio printing plate with engraved areas such that at least 80% of the whole surface of each security paper is covered with embossed intaglio patterns produced by engraved areas of the intaglio printing plate which are inked or with a combination of embossed intaglio patterns and flat intaglio patterns, which flat intaglio patterns are produced by unengraved areas of the intaglio printing plate which are inked after wiping of the intaglio printing plate, at least a part of the embossed intaglio patterns and/or flat intaglio patterns being printed with a transparent or semi-transparent intaglio ink. The transparent or semi-transparent intaglio ink is applied in engraved areas and/or unengraved areas of the intaglio printing plate so as to seal substantially the whole surface of the security papers with a protective pattern composed of intaglio patterns. Also described are intaglio printing presses for implementing the said process and the resulting security papers.

Abstract: The invention relates to a security element for a data carrier, such as banknotes, securities, checks, credit cards, ID cards and similar documents. A substrate comprises a first layer of material and at least a first opaque layer (3) of material covering partially or totally the first layer of material. The first layer has at least two adjacent zones (1,2) of a different color. The element further comprises a pattern (4) formed by a partial engraving of said opaque layer (3). The pattern (4) extends at least partially on each of said zones (1,2) so that the pattern (4) comprises adjacent parts of different color in perfect register apparent through said opaque layer (3).
