SINGLE OR DUAL TRANSFER PROCESS FOR PREPARING AND TRANSFERRING SHARPLY DEFINED SINGLE ELEMENTS TO OBJECTS TO BE PROTECTED

摘要

A fast and reliable single or dual transfer process is provided. Unlike prior art foil transfer techniques, which rely on the very fragile nature of the transferred pattern and/or shape to obtain a clean break at the die edge, the present invention is directed toward relatively non-tearable or tear resistant materials that can be difficult or impossible to effectively transfer using these known foil transfer techniques. This problem is addressed by precision cutting, for example, patches in the relatively non-tearable or tear resistant material positioned on a carrier substrate and in one exemplary embodiment transferring areas surrounding the cut patches to a sacrificial carrier substrate. The resulting sharply defined, precision cut patches left on the carrier substrate may then be transferred to objects to be protected such as banknotes.

主权项

1. A pre-patch transfer sheet comprising:
a carrier substrate; and a pre-patch transfer assembly that is affixed along a first side of the carrier substrate and comprising:
at least one isolated element for transfer having (i) a micro-optic film material assembly that produces a synthetic image and (ii) an adhesive layer affixed along a first side of the micro-optic film material assembly opposite the carrier substrate; anda background area from which material has been removed that is adjacent to or surrounds the at least one isolated element for transfer.
