Abstract

A release liner for removably covering an adhesive surface is disclosed. The release liner includes a substrate configured in size and shape to cover an adhesive surface of an item. The substrate includes a first side configured to releasably attach to the adhesive surface and a second side opposite the first side. The release liner also includes one or more ink-printed features on the second side of the substrate and a varnish coating on the second side of the substrate. The varnish coating covers at least the one or more ink-printed features on the second side of the substrate.

Claims

1. A release liner for removably covering an adhesive surface, the release liner comprising:

a substrate configured in size and shape to cover an adhesive surface of an item, the substrate having

a first side configured to releasably attach to the adhesive surface, and

a second side opposite the first side;

one or more ink-printed features on the second side of the substrate; and

a varnish coating on the second side of the substrate, the varnish coating covering at least the one or more ink-printed features on the second side of the substrate.

2. The release liner of claim 1, wherein the varnish coating covers substantially all of the second side of the substrate.

3. The release liner of claim 1, further comprising:

one or more ink-printed features on the first side of the substrate; and

a vanish coating on the first side of the substrate, the varnish coating covering at least the one or more ink-printed features on the first side of the substrate.

4. The release liner of claim 3, wherein the varnish coating covers substantially all of the first side of the substrate.

5. The release liner of claim 1, wherein a visual pattern is formed on or in the varnish coating.

6. The release liner of claim 1, wherein a textural pattern is formed on or in the varnish coating.

7. The release liner of claim 1, wherein the varnish coating comprises a release agent.

8. The release liner of claim 1, further comprising a release agent on the first side of the substrate.

9. The release liner of claim 1, wherein the varnish coating is configured to prevent transfer of the one or more ink-printed features to the adhesive surface.

10. The release liner of claim 1, wherein the substrate is translucent or transparent.

11. A release liner for removably covering an adhesive surface, the release liner comprising:

a substrate configured in size and shape to cover an adhesive surface of an item;

one or more ink-printed features on at least one of a first side or an opposite second side of the substrate; and

a visual or textural pattern formed on or in a varnish coating applied to the substrate;

wherein the release liner is configured to be applied to an adhesive surface to prevent the adhesive surface from adhering to itself or another surface until the release liner is removed.

12. The release liner of claim 11, wherein the varnish coating covers the one or more ink-printed features.

13. The release liner of claim 11, wherein the varnish coating covers substantially all of the first side of the substrate.

14. The release liner of claim 13, wherein the varnish coating covers substantially all of the second side of the substrate.

15. The release liner of claim 11, wherein the coating is configured to prevent transfer of the one or more ink-printed features to the adhesive surface.

16. The release liner of claim 11, wherein the substrate is translucent or transparent.

17. A method for manufacturing a release liner, the method comprising:

providing a substrate;

forming one or more ink-printed features on a first side of the substrate;

applying a varnish coating to the substrate that covers at least the one or more ink-printed features on the first side of the substrate; and

applying a release agent to a second side of the substrate, the second side opposite the first side and configured to releasably attach to the adhesive surface.

18. The method of claim 17, further comprising:

forming one or more ink-printed features on the second side of the substrate; and

applying a varnish coating to the substrate that covers the one or more ink-printed features on the second side of the substrate.

19. The method of claim 18, wherein the varnish coating is applied to substantially all of the first side and the second side of the substrate.

20. The method of claim 17, further comprising forming a visual pattern on or in the varnish coating.

21. The method of claim 17, further comprising forming a textural pattern on or in the varnish coating.
