Ink cup assembly with non-magnetic force mechanism

A printing system, comprising:

• a printing plate comprising a surface and a depression formed in the surface for receiving ink for printing on a golf ball;
• an ink cup assembly configured to contact the surface of the printing plate and supply the depression with ink, the ink cup assembly comprising:
• an ink holder comprising:
• a first side comprising an open cavity;
• a second, opposite side comprising a pressure surface, wherein the pressure surface comprises at least one blind hole;
• and
• a perimeter wall between the first side and the second side;
• and
• a force mechanism configured to hold the ink cup assembly in contact with the surface of the printing plate, wherein the force mechanism comprises at least one spring positioned in the at least one blind hole and configured to apply a predetermined force to the pressure surface of the ink holder;
• and
• a movement mechanism configured to move the ink cup assembly between a first position on the printing plate and a second position on the printing plate while the ink cup assembly maintains contact with the surface of the printing plate, wherein the movement mechanism comprises a support structure comprising a counteracting surface, wherein the counteracting surface is adjacent to the pressure surface of the ink holder and the at least one spring is configured to act against the counteracting surface to apply the predetermined force to the pressure surface.
