<p>PURPOSE:To clearly print a character, such as a letter, by a method wherein the character is printed in oil ink or water ink on the surface of a golf ball and the protective coating of water clear paint or oil clear paint is formed on the character. CONSTITUTION:The ink in an ink bottle 1 of an ink-jetting printer is supplied to a nozzle 4. An electrostrictive element 5 is provided in the nozzle 4 and vibrated by an electric signal transmitted from a source 6 of excitation. The ink ejected from the nozzle 4 synchronizes with the period of vibration of the electrostrictive element 5 and becomes ink-particles with a definite size. A charged electrode 7 controls amounts of electricity charged on each of the particles. When passed through between deflecting electrodes 8, the particles of ink arrive at the surface of a golf ball 9 after being deflected according to the amounts of electricity charged. In this way, after the surface of the golf ball 9 is printed in oil ink or water ink by the ink-jetting printer, the protective coating of water clear paint or oil clear paint is formed on the character printed. Since the character printed in oil ink or water ink is coated by the clear paint, it has good durability, and since the letter, etc., and the protective coating have a property of the reverse each other, clear finishing is obtained without the printing-character blotting.</p> |
