A liquid pressure transfer print method for a steering wheel rim of an automobile is achieved by lowering the steering wheel rim within a predetermined time up to a boundary line of a primary transfer print portion without attaching an additional mask member to the other side surface of the steering wheel rim opposite to the primary transfer print portion after floating the transfer print film on liquid (a first transfer print step), half drying the polyvinyl alcohol layer coated on the primary transfer print portion of the steering wheel rim in the first transfer print step, for a predetermined time and at a predetermined rate (a half drying step), when the polyvinyl alcohol layer at the outer side of a first transfer print surface in the half drying step is dried in a gel state, flipping the steering wheel rim and lowering the other side surface to be transfer printed over the boundary line within a predetermined time (a second transfer print step), and soaking the steering wheel rim having the entire surface thereof completely transfer printed in solution for a predetermined time and cleaning the outside polyvinyl alcohol layers of the first and second transfer print surfaces by injecting the solution to the surface of the steering wheel rim for a predetermined time (an entire surface cleaning step). Thus, a plurality of subsequent steps can be omitted, thus remarkably improving productivity, one time cleaning step minimizes the amount of waste water generated so that environment pollution can be reduced.
