ABSTRACT The printing ink system of the invention is destined and appropriate for the production of opaque printed areas, which can be removed by rubbing or scratching, on predetermined areas or regions, which should perfectly be covered, of a flexible substrate by typographic or offset processes. The system comprises a release ink and a metal pigment containing covering ink to be printed on the release printings. The binder phase of both inks which are substantially solvent free, comprises mainly high reactive, oxidation drying products and monomers or prepolymers. Chemical drying is induced either by influence of air oxygen, optionally backed up by additional heat such as infra- red, or under the influence of ultraviolet light.
