Cold foil temporary tattoo and process for making the same
Described herein is/are cold foil adhesive methods for manufacturing temporary tattoo laminate devices, wherein the tattoos incorporate metallic foil and other decorative components. The methods provide a surprisingly rapid and efficient method for creating tattoo laminate devices which provide crisp, clear multi-color images temporary tattoos for the skin. The methods described herein provide a way to produce, in an offset printing press or flexographic printing press, numerous tattoo laminate devices at very high speeds, with unlimited colors, and crisp, clear images.
1. A method for producing a temporary foil tattoo, comprising the steps of:
(a) providing a base sheet;
(b) applying ink to the base sheet, to form a first ink layer;
(c) applying cold foil adhesive to the first ink layer, to form a first adhesive layer;
(d) applying cold foil to the first adhesive layer, to form a foil layer;
(e) applying ink to the cold foil layer to form a second ink layer;
(f) applying a second adhesive to the second ink layer, to form a second adhesive layer for contacting a substrate to which the temporary tattoo may be applied; and
(g) applying a protective liner sheet to the second adhesive layer.
2. The method of claim 1 , wherein steps (b), (c), (d) and (e) are performed by a print unit in an offset printing press.
3. The method of claim 1 , wherein steps (b), (c), (d) and (e) are performed by a print unit in a flexographic printing press.
4. The method of claim 1 , wherein the cold foil adhesive applied in step (c) is skin-safe and substantially transparent.
5. The method of claim 4 , wherein the cold foil adhesive applied in step (c) is uncolored.
6. The method of claim 5 , wherein the cold foil adhesive applied in step (c) is uncolored, acrylate-based adhesive.
7. The method of claim 4 , wherein the first adhesive layer is non-continuous.
8. The method of claim 4 , wherein step (c) comprises applying the cold foil adhesive only to portions of the first ink layer to which the foil in step (d) is desired to be applied.
9. The method of claim 1 , wherein in step (b), step (e) or in both steps (b) and (e) each of the steps comprises applying multiple colors of ink wherein each color ink is applied using a print unit in an offset printing press or in a flexographic printing press.
10. The method of claim 9 , wherein in step (b), step (e) or both steps (b) and (e), the ink is applied via four-color process.
11. The method of claim 10 , wherein the ink is CMYK ink.
12. The method of claim 1 , wherein
step (a) comprises providing a base sheet having a release coating.
13. The method of claim 12 , wherein
the release coating is capable of releasing upon application of water, pressure or heat.
14. The method of claim 1 , wherein
step (a) comprises providing a base sheet having a thickness in the range of about 0.004 inches to about 0.0012 inches.
15. The method of claim 1 , wherein
step (b) comprises providing a pre-coating to the base sheet to form a pre-coated base sheet, and applying ink to the pre-coated base sheet to form the first ink layer.
16. The method of claim 15 , wherein
the pre-coating comprises a skin-safe, substantially clear composition.
17. The method of claim 16 , wherein
the pre-coating is applied via screen printing, gravure printing or offset printing.
18. The method of claim 1 , wherein
the adhesives and inks are skin safe.
19. The method of claim 1 , wherein the method is performed in 2 passes through an offset printing press or in 1 or 2 passes through a flexographic printing press and wherein
each step is performed by a print unit,
step (a) comprises providing a base sheet having a release coating capable of releasing upon application of water, pressure or heat,
step (b) comprises providing a pre-coating to the base sheet to form a pre-coated base sheet, and applying ink to the pre-coated base sheet to form the first ink layer, and
step (c) comprises applying a skin-safe and substantially transparent cold foil adhesive.
20. The method of claim 19 , wherein
step (g) comprises applying a substantially transparent protective liner sheet.
21. A method for producing a temporary foil tattoo, comprising the steps of:
(a) providing a base sheet having a release coating;
(b) applying ink to the base sheet, to form a first ink layer;
(c) applying cold foil adhesive to the first ink layer, to form a first adhesive layer;
(d) applying cold foil to the first adhesive layer, to form a foil layer;
(e) applying ink to the cold foil layer to form a second ink layer;
applying a second adhesive to the second ink layer, to form a second adhesive layer for contacting a substrate to which the temporary tattoo may be applied; and
(g) applying a protective liner sheet to the second adhesive layer; and
wherein steps (b), (c), (d) and/or (e) are performed by a print unit in an offset printing press or in a flexographic printing press.
