Abstract

A method of forming a printed food or baked product, and the product itself comprises forming a hard, non-porous icing surface by drying an icing mixture and printing one or more edible inks on the hard surface of the icing using a printing pad having an edible silicone oil therein. The icing may be in the form of a coating on a hard baked product. The specific gravity of the icing mixture before drying is between about 1.0 and 2.5 and, preferably, between about 1.05 and 1.5. The hard baked product has a finished moisture of between about 2-10% by weight of the finished baked product and, preferably, between about 2-8% by weight.

Claims

1. A method of forming a printed food product comprising the steps of:

forming an icing mixture having a specific gravity of between 1.0 and 2.5,

shaping said icing mixture to have a surface,

drying said icing mixture to form a hard, non-porous icing surface,

transfer printing at least one edible ink to said hard dried surface of said icing, and

drying said ink.

2. The method of claim 1, wherein the specific gravity is between about 1.05 and 1.5.

3. The method of claim 1 wherein said ink is printed onto said hard icing surface by transferring said ink from a pad having an edible silicone oil therein.

4. The method of claim 1 wherein a plurality of inks of different colors are transferred by printing to said hard icing surface.

5. The method of claim 1, wherein said icing mixture is coated on a substantially flat surface of a hard baked product, said hard surface of said icing also being substantially flat.

6. The method of claim 5, wherein said hard baked product has a finished mositure of between about 2-10% by weight of the finished baked product.

7. The method of claim 6, wherein said finished moisture is between about 2-8% by weight of the finished baked product.

8. The method of claim 7, wherein the specific gravity of said icing mixture is between about 1.05 and 1.5.

9. The method of claim 7, wherein a plurality of inks of different colors are transferred by printing to said icing surface.

10. A printed food product comprising:

a dried, hard, non-porous icing having a surface dried from an icing mixture having a specific gravity of between 1.0 and 2.5 before drying, and at least one edible ink transfer printed on said surface.

11. The product of claim 10, wherein the specific gravity is between about 1.05 and 1.5.

12. The product of claim 10, wherein a plurality of inks of different colors are printed on said icing surface.

13. The product of claim 10, including a hard baked product having a substantially flat surface, said icing coating said flat surface and also having a substantially flat surface to which said ink is transferred by printing.

14. The product of claim 13, wherein said hard baked product has a finished moisture of between about 2-10% by weight of the finished baked product.

15. The product of claim 14, wherein said finished moisture is between about 2-8% by weight of the finished baked product.

16. The product of claim 15, wherein the specific gravity of said icing mixture is between about 1.05 and 1.5.

17. The product of claim 15, wherein a plurality of inks of different colors are printed on said surface of said hard icing surface.
