Abstract
The invention relates to an absorbent medium for improving the overprintability, in particular by inkjet printing, of a security element, in particular an optically variable security element, comprising a binder, at least one pigment and an in particular aqueous solvent. The invention furthermore relates to a transfer film with an absorbent layer made of such an absorbent medium as well as a method for personalizing a security element using such a transfer film.
Claims11
A method for personalizing a security element, with the steps of:
- providing a security element;
- applying the security element to a substrate;
- applying an at least partial absorbent layer made of an absorbent medium;
- applying a personalization feature to the absorbent layer by inkjet printing,
- wherein the absorbent layer is applied by hot embossing of a transfer film.
A method for personalizing a security element, with the steps of:
- providing a security element;
- applying the security element to a substrate;
- applying an at least partial absorbent layer made of an absorbent medium;
- applying a personalization feature to the absorbent layer by inkjet printing,
- wherein the absorbent layer and/or the security element are transferred onto an auxiliary carrier and die-cut into a predefined shape before being applied.
A method for personalizing a security element, with the steps of:
- providing a security element;
- applying the security element to a substrate;
- applying an at least partial absorbent layer made of an absorbent medium;
- applying a personalization feature to the absorbent layer by inkjet printing,
- wherein, before application of the absorbent layer to the security feature, a further printed layer is applied by offset or intaglio printing.
A method for personalizing a security element, with the steps of:
- providing a security element;
- applying the security element to a substrate;
- applying an at least partial absorbent layer made of an absorbent medium;
- applying a personalization feature to the absorbent layer by inkjet printing,
- wherein, before the application of the personalization feature, a security feature is printed on the absorbent layer using a fluorescent indicator printing ink and/or UV-active indicator printing ink and/or an indicator printing ink that bleeds under the influence of water and/or under the influence of solvents.
A method for personalizing a security element, with the steps of:
- providing a security element;
- applying the security element to a substrate;
- applying an at least partial absorbent layer made of an absorbent medium;
- applying a personalization feature to the absorbent layer by inkjet printing,
- wherein a security element is provided which comprises one or more of the following layers:
- a carrier ply,
- a detachment layer,
- a protective layer,
- a replication layer,
- a reflective layer,
- a color varnish layer,
- an adhesive layer, and
- wherein a security element is provided which has two adhesive layers, which form two opposite surfaces of the security element after removal of a carrier ply.
