    Abstract: The present invention provides a method for arranging dimples on a golf ball surface in which the dimples are arranged in a pattern derived from at least one irregular domain generated from a regular or non-regular polyhedron. The method includes choosing control points of a polyhedron, generating an irregular domain based on those control points, packing the irregular domain with dimples, and tessellating the irregular domain to cover the surface of the golf ball. The control points include the center of a polyhedral face, a vertex of the polyhedron, a midpoint or other point on an edge of the polyhedron and others. The method ensures that the symmetry of the underlying polyhedron is preserved while minimizing or eliminating great circles due to parting lines.

    Abstract: A golf ball dimple half profile is disclosed herein that can be defined by a piecewise function. The sub-functions that define the piecewise function can include, for example, a catenary function and a Gabriel's horn function. A transition between the sub-functions defining the piecewise function is smooth. The sub-functions can have opposing concavities, and at least one of the sub-functions can have a non-constant radius of curvature. The golf ball dimple half profile is rotated about the dimple's centroid to create the full dimple profile.

    Abstract: A method for printing a marking on a golf ball includes arranging ink in an etching pattern on a printing plate, matching a reference position on the plate to a reference position on the golf ball, transferring the ink from the printing plate to a pad, and transferring the ink from the pad to the golf ball such that the golf ball includes the marking. The pattern includes an etch corresponding to the marking, wherein the etch differs from the marking in a manner dependent on the position of the marking on the golf ball. The marking that results on the golf ball is a linear marking, and a centerline of the linear marking lies entirely within a marking plane that is not a centerline plane of the golf ball, and wherein the edges of the marking are parallel with the marking plane.

    Abstract: Golf ball having a generally spherical surface and comprising a plurality of dimples separated by a land area formed on the ball surface, wherein the plurality of dimples includes at least one non-spherical dimple having a non-axially symmetric plan shape and a defined point of maximum dimple depth, wherein: (i) each dimple cross-section of the non-spherical dimple consists of two arcs, each arc extending from the defined point of maximum dimple depth to a point at the land area of the golf ball; and (ii) every point on the perimeter of the non-spherical dimple is located at a radial angle, θ, about a unit circle, where 0≤θ≤2π, and the edge angle value of the non-spherical dimple at any given point on the perimeter is defined by the solution of an edge angle function f(θ), wherein f(θ) is a non-periodic, continuous, differentiable function.
