ABSTRACT:
A golf ball is provided with a marking portion including a hologram implementing a color and/or pattern produced by optical interference. The marking portion is provided on the entire surface of the golf ball or only in dimples. The marking portion including a hologram reflects light and thereby glitters, and is visually recognized as a three-dimensional image, thereby improving visibility of the ball from a distance. The marking portion including a hologram allows an image to be readily reproduced by irradiating a laser beam thereto. Thus reproduced image facilitates an automated inspection for the appearance of the marking portion.
