Abstract
A ribbon supply roll for use in a plastic card or passport personalization machine. The ribbon supply roll includes a zone-coated splice tape with a pressure sensitive adhesive on a backing film where the adhesive does not flow or ooze beyond the edges of the backing film. Therefore, a transferrable material on a winding layer in contact with the splice tape is not pulled away. For example, portions of the backing film of the splice tape are not coated with the adhesive which permits the adhesive to flow or ooze when pressure is applied to the splice tape. However, the adhesive does not flow enough to flow beyond the edges of the backing film.

A ribbon supply roll for use in a plastic card or passport personalization machine, the ribbon supply roll comprising:
- a core;
- a ribbon wound on the core, at least a portion of the ribbon includes a carrier film and a transferrable material disposed on the carrier film, wherein the transferrable material is suitable for being transferred from the carrier film to a plastic card or a passport in the plastic card or passport personalization machine;
- a splice tape disposed along a length of the ribbon and interconnecting two initially separate sections of the ribbon, the splice tape includes a backing film and a pressure sensitive adhesive on the backing film, and the pressure sensitive adhesive does not extend beyond edges of the backing film.
A method of forming a ribbon supply roll of a plastic card or passport personalization machine, the method comprising:
- interconnecting a first section of ribbon and a second section of ribbon using splice tape, at least one of the first section of ribbon and the second section of ribbon includes a carrier film and a transferrable material disposed on the carrier film, wherein the transferrable material is suitable for being transferred from the carrier film to a plastic card or a passport in the plastic card or passport personalization machine, and the splice tape includes a backing film and a pressure sensitive adhesive on the backing film, and there are gaps between the pressure sensitive adhesive and edges of the backing film;
- winding the interconnected first section of ribbon and second section of ribbon onto a core.
