Noncontact printing on subsurface layers of translucent cover golf balls
First Claim
1. A method of forming indicia on a golf ball comprising the steps of:
- (a) providing a first golf ball subassembly having a first outer surface, the first subassembly being selected from the group consisting of a core layer, an intermediate layer, and a combination thereof;
(b) utilizing a noncontact printing system to mark the first outer surface with ink that forms a first indicia;
(c) foaming, around the first golf ball subassembly, a second golf ball subassembly with a second outer surface, the second subassembly comprising a cover layer, wherein the second golf ball subassembly is partially transparent or translucent; and
(d) optionally utilizing a printing system to mark the second outer surface with an ink that forms a second indicia, and wherein at least one of the intermediate or cover layers comprises reflective or optically active particulates having faces with an individual reflectance of at least about 75%.

Abstract
The present invention relates to a noncontact printing method for applying indicia, such as insignia or stripes, on at least one subsurface layer of a transparent or translucent cover golf ball, e.g. the core, or one or more intermediate layers. The indicia may be visible in ambient light or are only visible when exposed to specific non-ambient light wavelengths, e.g. ultraviolet wavelengths. Advantageously, this method of noncontact printing on subsurface golf ball layers substantially improves the durability of indicia because such indicia are protected from direct abrasion and club impacts by the cover. Moreover, unlike pad printing, noncontact printing forms indicia that are not susceptible to ink degradation because the indicia are solid markings created by very small discrete dots. In one embodiment, both the cover and the intermediate layer(s) may be transparent or translucent and thusly decorated to achieve previously unattainable image depth effects.
