The ink formulation contains a coloring matter, pigment, and a carrier containing nitrocellulose, solvent and a plasticizer. The ink formulation contains 1-40% by weight pigment; above 10% by weight nitrocellulose, 40-80% by weight solvent, and 1-25% by weight plasticizer. This ink formulation avoids the step of pre-coating the ball prior to printing where the ball has a cover made from an ionomer resin (SURLYN TM ). |
