PURPOSE: A method for printing the rear side of a transparent injection molded product based on a heat transferring film is provided to prevent the high failure rate of a molding process by simultaneously implementing a molding operation and a trimming operation in the process of compressing a heat transferring film and a transparent injection molded product. CONSTITUTION: A method for printing the rear side of a transparent injection molded product based on a heat transferring film includes the following: a heat transferring film with printing patterns is pre-heated; the pre-heated heat transferring film(110) is introduced into a mold(120) such that the film faces a transparent injection molded product(150); the film and the transparent injection molded product are compressed to transfer the printing patterns on the rear side of the transparent injection molded product based on vacuum or steam. |
