Claims4
A dual cure method for curing printed ink on a golf ball, the method comprising:
- printing an image onto a surface of a golf ball using an UV curable ink, the image covering an area less than the entire surface of the ball;
- exposing only the printed area to infrared radiation, wherein the infrared radiation is directed to the area where the image is printed for a suitable duration of time to allow the image to cure on the surface for a first time;
- subsequently exposing the area where the image is printed to ultraviolet radiation, for a suitable duration of time to allow the image to cure on the surface for a second time;
- and
- wherein the printed area after the dual cure method has an image loss of no greater than approximately one (1) percent, when subjected to 100 cycles of the ‘cannon’ golf ball decoration durability test.
