A monotube shock absorber assembly includes a housing, a gas cup slidably disposed in the interior of the housing, and a piston slidably disposed in the interior of the housing to define an oil compression chamber between the piston and the gas cup. The hard rubber embossing surface is biased toward a second embossing surface selected from the group consisting of the surface of a nip roll and a foraminous web support engaging a support embossing roll. The second car is kept in a suspension ratio of 1:1 and is connected to its counterweight by means of two cable strands associated with different sides of the second car and led over the traction sheave of the second car. The temperature value is passed to the digital base band circuit. In the present invention, since the curing agent contained in the paint covering the mark is used to cure the resin component forming the mark, there is no increase in the viscosity or the gellation of the ink for printing the mark, and thus the mark is printed well during the production of the golf ball.
