4. The process of claim 2, wherein the adhesive is uncured when it initially contacts the surface of the article, and further comprising a step of curing the adhesive after it contacts the surface of the article.

5. The process of claim 2, wherein the adhesive is partially cured when it initially contacts the surface of the article, and further comprising a step of curing the adhesive after it contacts the surface of the article.

6. The process of claim 2, wherein the adhesive is uncured when the transfer material is transferred onto the surface of the article, and further comprising a step of curing the adhesive after transferring the transfer material onto the surface of the article.

7. The process of claim 2, wherein the adhesive is partially cured when the transfer material is transferred onto the surface of the article, and further comprising a step of further curing the adhesive after transferring the transfer material onto the surface of the article.

8. The process of claim 1, wherein the transfer component with the transfer material thereon is deformed prior to contacting the surface of the article.

9. The process of claim 1, wherein the transfer component with the transfer material thereon is deformed while contacting the surface of the article.

11. The process of claim 1, wherein the step of modifying the portion of the transfer component with the transfer material thereon to conform the transfer component with the transfer material thereon to at least a portion of the surface of the three-dimensional article comprises stretching at least the portion of the transfer component with the transfer material thereon.

12. The process of claim 1, wherein the step of modifying the portion of the transfer component with the transfer material thereon to conform the transfer component with the transfer material thereon to at least a portion of the surface of the three-dimensional article comprises contracting at least the portion of the transfer component with the transfer material thereon.

13. The process of claim 11, wherein the portion of the transfer component with the transfer material thereon is stretched prior to contacting the surface of the article.
