Liquid pressure transfer printing method for steering wheel rim of automobile

A liquid pressure transfer print method for transferring a printed pattern to a steering wheel rim divided into two side surfaces in a lengthwise direction, using a transfer film having a pattern layer disposed on a polyvinyl alcohol layer, the method comprising:

• floating a first polyvinyl alcohol transfer print film on a liquid;
• without attaching a mask member to the steering wheel rim on a second of the two side surfaces, opposite a first of the two side surfaces, the first of the side surfaces being a primary transfer print portion, lowering the steering wheel rim into the liquid on the transfer print film for a first time period, to a boundary line of the primary transfer print portion, and transferring a polyvinyl alcohol layer onto the primary transfer print portion;
• drying the polyvinyl alcohol layer coating on the primary transfer print portion of the steering wheel rim for a second time period and at a drying amount;
• floating a second polyvinyl alcohol layer on the liquid;
• when the polyvinyl alcohol layer on the primary transfer print portion has dried to a gel state, flipping the steering wheel rim and lowering the second side surface to beyond the boundary line, for a third time period, onto the second polyvinyl alcohol layer floated on the liquid;
• removing the steering wheel rim from the liquid;
• and
• soaking the steering wheel rim in a solution and cleaning the polyvinyl alcohol layers on the first and second transfer print surfaces by spraying the solution against the steering wheel rim.
