  • Publication number: 20150035268
    Abstract: The present invention relates to the field of the intaglio printing process. In particular, the present invention relates to a method that combines intaglio inks curable by oxidation with UV-VIS-curable intaglio inks on one intaglio plate or cylinder. The disclosed method results in an intaglio printed security element using advantageously the unalike properties of the different inks while enabling the printing on a standard printing press in one printing step.

  • Patent number: 8636307
    Abstract: The present invention relates to printing inks for the intaglio printing process, also referred to as engraved steel die printing process. In particular, oxidatively curing inks comprising a combination of fusible wax and a UV curing binder component are disclosed. These inks can be printed on a standard printing press, and, through a short UV irradiation after printing, allow to significantly reduce or eliminate the undesired set-off which can occur after printing and stacking the printed sheets. Using the inks of the present invention results in less set-off contaminated printed sheets, allowing for a higher pile-stacking of the printed good, for the use of increased engraving depths, of a more challenging intaglio design, and for the printing on less porous substrates, while enabling the printing on a standard printing press, and offering the possibility of using a lower printing plate temperature.
