Abstract

A method of laminating a transfer section of a transfer layer to a substrate is performed using a reverse-image transfer printing device. The device includes a transfer ribbon, a print ribbon, a print head, and a laminating device. The transfer ribbon comprises the transfer layer, which is attached to a carrier layer. The print head is configured to transfer print material from the print ribbon to the transfer layer. Non-transfer portions of the transfer section are heated to a deactivation temperature using the print head. The transfer section is laminated to the substrate by heating the non-transfer portions and transfer portions of the transfer section using the laminating device. This bonds the transfer portions the substrate. The carrier layer is the removed from the transfer portions leaving the transfer portions bonded to the substrate. The non-transfer portions remain attached to the carrier layer.

First claim

What is claimed is:

1. A method of laminating a transfer section of a transfer layer to a substrate using a reverse-image transfer printing device, which includes a transfer ribbon comprising the transfer layer attached to a carrier layer, a print ribbon, a print head configured to transfer print material from the print ribbon to the transfer layer, and a laminating device, the method comprising:
heating non-transfer portions of the transfer section to a deactivation temperature using the print head; and
laminating the transfer section to the substrate comprising:
heating the non-transfer portions and transfer portions of the transfer section using the laminating device; and
bonding the transfer portions to the substrate using the laminating device; and

removing the carrier layer from the transfer portions, wherein the non-transfer portions remain attached to the carrier layer.

2. The method according to claim 1 , wherein heating non-transfer portions of the transfer section comprises heating the non-transfer portions through the print ribbon using the print head.

3. The method according to claim 2 , wherein heating non-transfer portions of the transfer section comprises heating the non-transfer portions through the print ribbon using the print head without transferring print material from the print ribbon to the non-transfer portions.

4. The method according to claim 3 , wherein:
the print ribbon includes a blank panel; and
heating non-transfer portions of the transfer section comprises heating non-transfer portions of the transfer section through the blank panel.

5. The method according to claim 2 , wherein heating non-transfer portions of the transfer section comprises transferring print material from the print ribbon to the non-transfer portions.

6. The method according to claim 1 , comprising printing an image on the transfer portions using the print head comprising:
heating portions of the print ribbon to a print temperature using the print head; and
transferring print material from the print ribbon to the transfer section in response to heating portions of the print ribbon;
wherein the deactivation temperature is greater than the print temperature.

7. A The method according to claim 1 , wherein:
the non-transfer portions of the transfer section correspond to features of the substrate selected from the group consisting of embedded circuitry, an electrical contact, a magnetic stripe, a signature panel, and a holographic image; and
the transfer section laminated to the substrate includes openings over the one or more features of the substrate corresponding to the non-transfer portions.

8. The method according to claim 1 , wherein:
the substrate includes a leading edge, a trailing edge opposite the leading edge, and first and second opposing side edges extending between the leading and trailing edges; and
the non-transfer portions of the transfer section are selected from the group consisting of a leading edge portion of the transfer section corresponding to the leading edge of the substrate, a trailing edge portion of the transfer section corresponding to the trailing edge of the substrate, and side edge portions of the transfer section corresponding to the side edges of the substrate.

9. The method according to claim 1 , further comprising heating a portion of the transfer layer that adjoins an edge of the transfer section to the deactivation temperature using the print head.

10. A method of laminating a transfer section of a transfer layer to a substrate using a reverse-image transfer printing device, which includes a transfer ribbon comprising the transfer layer attached to a carrier layer, a print ribbon, a print head configured to transfer print material from the print ribbon to the transfer layer, and a laminating device, the method comprising:
heating one or more non-transfer portions of the transfer layer adjoining at least one edge of the transfer section to a deactivation temperature using the print head; and
laminating the transfer section to the substrate comprising:
heating the transfer section using the laminating device; and
bonding transfer portions of the transfer section to the substrate using the laminating device; and

removing the carrier layer from the transfer portions, wherein the non-transfer portions remain attached to the carrier layer.

11. The method according to claim 10 , wherein:
the transfer section includes a leading edge, a trailing edge opposite the leading edge, and first and second opposing side edges extending between the leading and trailing edges; and
the one or more non-transfer portions are selected from the group consisting of a leading edge portion adjoining the leading edge of the transfer section, a trailing edge portion adjoining the trailing edge of the transfer section, and side edge portions each adjoining one of the side edges of the transfer section.

12. The method according to claim 10 , wherein heating one or more non-transfer portions of the transfer layer comprises heating the one or more non-transfer portions through the print ribbon using the print head.

13. The method according to claim 12 , wherein heating one or more non-transfer portions of the transfer layer comprises heating the one or more non-transfer portions through the print ribbon using the print head without transferring print material from the print ribbon to the non-transfer portions.

14. The method according to claim 10 , wherein:
the method comprises heating non-transfer portions of the transfer section to the deactivation temperature using the print head; and
laminating the transfer section comprises:
heating the non-transfer portions and the transfer portions of the transfer section using the laminating device; and
bonding the transfer portions to the substrate using the laminating device; and

the non-transfer portions of the transfer section remain attached to the carrier layer following removing the carrier layer from the transfer portions.
