Abstract

A golf ball having an indicia produced by ink jet printing is disclosed. An ink composition containing a coloring agent and a resin is dispensed on a transfer medium, using an ink jet printer, to form an indicia. The indicia is transferred from the transfer medium to the dimpled surface of a golf ball. In another form of the invention, an indicia is applied directly to a golf ball, without a transfer medium. In this method, an indicia receiving layer is applied on at least a portion of the golf ball surface, then the indicia is printed directly on the indicia receiving layer using an ink jet printer. The indicia on the golf ball has an impact resistance suitable for use in competitive play.

Claims

1. A method of applying at least one indicia to a dimpled surface of a golf ball, the method comprising:

obtaining an ink composition suitable for use in ink jet printing;

forming an indicia receiving layer on at least a portion of the dimpled surface of the golf ball, the indicia receiving layer containing a material which promotes at least one of absorption, adhesion and clarity of the indicia; and

printing an indicia on the indicia receiving layer using an ink jet printer, the indicia on the dimpled surface of the golf ball having a thickness of less than 100 microns.

2. The method according to claim 1 wherein the indicia receiving layer comprises a polyurethane.

3. The method according to claim 1 wherein said material promotes absorption, adhesion and clarity of the indicia.

4. The method according to claim 1 wherein the material which promotes at least one of absorption, adhesion and clarity of the indicia includes at least one member selected from the group consisting of talc, amorphous silica, bentonite clay, and magnesium silicate.

5. The method according to claim 1 further comprising;

forming a protective coating over the indicia.

6. The method according to claim 1 wherein the indicia is printed directly on the surface of the indicia receiving layer using the ink jet printer.

7. The method according to claim 1 wherein the indicia is printed on a transfer medium using the ink jet printer, and the indicia is subsequently transferred to the surface of the indicia receiving layer.

8. The method according to claim 1 wherein the indicia receiving layer is a primer coating layer.

9. The method according to claim 1 wherein the indicia receiving layer is a cover.

10. The method according to claim 1 wherein the ink composition comprises a UV curable resin, further comprising:

curing the indicia after the indicia has been printed on the indicia receiving layer.

11. The method according to claim 1 wherein the ink composition comprises a polymer resin.

12. The method according to claim 1 wherein the ink composition is an aqueous-based formulation.

13. The method according to claim 1 wherein the ink composition is a non-aqueous-based formulation.

14. A method of applying at least one indicia to a golf ball, comprising:

obtaining an ink composition suitable for use in ink jet printing, the ink composition comprising aluminum trihydroxide in an amount ranging from 10 to 50 weight percent of the total weight of the ink composition and an aliphatic urethane triacrylate;

printing an indicia on the surface of a golf ball using a drop-on-demand ink jet printer; and

forming a protective coating over the indicia.

15. The method according to claim 14 wherein the drop-on-demand printer does not have electronic deflection of ink particles.

16. The method according to claim 14 wherein the resolution of the indicia is at least about 300 d.p.i. (about 120 dots per cm).

17. The method according to claim 14 wherein the resolution of the indicia is at least about 600 d.p.i. (about 240 dots per cm).

18. The method according to claim 14 wherein the resolution of the indicia is at least about 1000 d.p.i. (about 390 dots per cm).
