Most of the fingerprints found at crime scenes are in latent fingerprint forms, and it is difficult to observe those fingerprints with the naked eye. Even if it is assumed that a latent fingerprint is remaining on an object, the method of developing the latent fingerprint differs depending on the surface type of the object. Therefore, a study must be performed by imprinting a latent fingerprint on an object, which is similar to the evidence found at a crime scene, to find an appropriate latent fingerprint development method. To do this, time and costs occur to recruit research participants, and these may cause disruption on arresting a suspect in a short time. Lothar Schwarz’s artificial latent fingerprint printing method, using an artificial sweat solution and an inkjet printer, can be used in a latent fingerprint research instead of using real human fingerprints. Although the major purpose of Schwarz’s method is to print out uniform fingerprint images on an A4 paper. Therefore, this approach has a limitation that it can only make imprints of fingerprints on thin and flexible materials such as copy papers and PVC films. To address this shortcoming, a Synthetic Fingerprint Generator(SFinGe, University of Bologna) computer program, a Printed Circuit Board(PCB) technique, and liquid latex are used to create an artificial fingerprint cast. With this new method, artificial latent fingerprint can be made on any surface types of material to find an appropriate latent fingerprint development method quickly during police investigations.

법과학 분야는 사회정의 구현에 있어 크나큰 가치가 있음에도 불구하고 우리나라에서는 이 분야에 대한 인식이 미흡하여 선진 외국에 비해 침체되어 있는 실정이다. 이에 우리나라에서도 법과학 분야와 관련 있는 학계, 연구기관, 수사기관 등 유관 단체들로 구성된 한국 법과학회를 창립하여 이 분야를 활성화 시켜 과학수사를 한층 더 발전시키기 위함을 목적으로 한다.
