Metallic Patch GOLDswitch
A metallic pigment that is made up as an ink and is printed on top of the polymer substrate as a patch. It has a metallic glitter. When changing the angle of view, glitter intensity changes, but not the colour (fig. 1). This patch may then be used as a platform for other security features such as intaglio contrast effect (ICE) and transparent intaglio disappearing effect (TIED).
Similar to metallic ink on the paper substrate.
