Abstract
A bowling ball, rather than being engraved with a decoration, is printed with the decoration, relying on graft polymerization chemistry by which the printing fluid, offset to the ball in decoration form, is effectively bonded to the ball which may be rubber or other polymer capable of participating in graft polymerization.
