Abstract
A printed security feature for a security document including a substrate, the security feature comprising: a first functional effect ink printed on a first surface of the substrate, and a second functional effect ink printed on the first and/or a second surface of the substrate, at least partially overlapping the first functional effect ink, wherein the first and the second functional effect inks in combination create an imagery feature which resembles an appearance of a security thread.
Claims21
A printed security feature for a security document, said security document including a transparent or translucent substrate of polymeric material, the security feature comprising:
- a first functional effect ink printed directly onto a first surface of the substrate, and
- a second functional effect ink printed directly onto the first and/or a second surface of the substrate, at least partially overlapping the first functional effect ink,
- wherein the first and the second functional effect inks in combination create an imagery appearance of a security thread that is an elongate strip having a length that is greater than its width and extends between a first edge and a second edge of the security document,
- wherein at least one of the first functional effect ink and the second functional effect ink includes a colour switching ink, which displays a variable colour appearance when a viewing condition and/or a viewing angle changes, or
- wherein at least one of the first functional effect ink and the second functional effect ink includes an ink comprising metallic ink particles, which create a metallic appearance;
- or
- wherein the first and second functional effect inks include fluorescent, luminescent, phosphorescent inks, photochromic, thermochromic, hydrochromic, or peizochromic inks.
A printed security feature for a security document, said security document including a transparent or translucent substrate of polymeric material, the security feature comprising:
- a first functional effect ink printed directly onto a first surface of the substrate;
- a second functional effect ink printed directly onto the first and/or a second surface of the substrate, at least partially overlapping the first functional effect ink, and
- a non-functional effect ink printed in one or more ink layers to create a shadow image which is observable in reflection or transmission,
- wherein the first and the second functional effect inks in combination create an imagery appearance of a security thread that is an elongate strip having a length that is greater than its width and extends between a first edge and a second edge of the security document,
- wherein at least one of the first functional effect ink and the second functional effect ink includes a colour switching ink, which displays a variable colour appearance when a viewing condition and/or a viewing angle changes, or
- wherein at least one of the first functional effect ink and the second functional effect ink includes an ink comprising metallic ink particles, which create a metallic appearance or
- wherein the first and second functional effect inks include fluorescent, luminescent, phosphorescent inks, photochromic, thermochromic, hydrochromic, or peizochromic inks.
