A golf ball including an outer surface having dimples located on the outer surface, at least one core, at least one mantle layer, at least one cover layer, and a plurality of images located on the outer surface, the images being provided with at least two contrasting colors, wherein the plurality of images each have a Major Peak Ratio of between 0.18 and 1, a Major Valley Ratio of between 0.18 and 1, a slope value of between −5 and 5, and an intercept value between 5 and 80.

A printing system facilitates the printing of articles of manufacture. The system includes an array of printheads, a support member positioned to be parallel to a plane formed by the array of printheads, a member movably mounted to the support member, an actuator operatively connected to the movably mounted member, an object holder configured to mount to the movably mounted member, and a controller operatively connected to the plurality of printheads and the actuator. The controller is configured to operate the actuator to move the object holder past the array of printheads and to operate the plurality of printheads to eject marking material onto objects held by the object holder as the object holder passes the array of printheads. The support member and printhead array are oriented vertically to enable the printing system to be installed in a vertical cabinet that provides a small footprint in a non-production environment.

A golf ball scriber includes: a clip comprising a first clip body and a second clip body which are connected by a pivot shaft; a clamping groove surface disposed on an inner clamping surface of the clip; a sealed brush device; a first clip groove and a second clip groove symmetrically arranged on a respective outer wall of the first clip body and the second clip body; a scribing ruler disposed at a bottom surface of the first clip groove; a strip-shaped chamfered groove disposed on the scribing ruler away from the clamping groove surface; and a strip-shaped scribing groove disposed on the chamfered groove which corresponds to the clamping groove surface, wherein the scribing ruler, the chamfered groove, and the scribing groove share a central line, and the brush device is in sliding connection with the first clip groove disposed on the first clip body.

A method of manufacturing an article comprises etching an etched feature on a surface of a first polymeric sheet, and forming a fluid-filled bladder element from the first polymeric sheet, with the fluid-filled bladder element having a sealable internal cavity that retains fluid. The method includes assembling the bladder element in the article so that a first portion of the bladder element having the etched feature is exposed to view, and a second portion of the bladder element is blocked from view by the article. An article includes the bladder element with the etched feature.

A tape is disclosed for use with a ball having a seam, wherein the seam has a predetermined seam color. The tape includes an adhesive layer formed of an adhesive material configured to attach to the seam, and a carrier layer formed of a carrier layer material, wherein the carrier layer has a custom color that is different than the predetermined seam color. Additionally, methods are disclosed for customizing a color of the seam of the ball using multiple tape segments. Still further, a kit is disclosed that includes the ball, a first tape having a first custom color, and a second tape having a second custom color.

A method for manufacturing a golf ball having a non-uniform dot pattern is provided. Firstly, a semi-finished product of a golf ball is provided, which includes a ball body and a base layer covering an outer surface of the ball body. After that, the semi-finished product of the golf ball is rotated at a predetermined rotation speed, and a color paint is applied to the semi-finished product of the golf ball in a spraying manner from each of an upper position and a lower position.
