20080248897 | NONCONTACT PRINTING ON SUBSURFACE LAYERS OF TRANSLUCENT COVER GOLF BALLS - 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.
