The footwear impression found at the crime scene can serve as an important clue in identifying the suspect. Footwear impression found in the field appear in various forms, and in the case of planar footprints, additional treatment may be needed to increase the contrast between the background and footwear impressions to facilitate visual observation. There is a wide variety of surfaces on which footwear impressions can be left, so a suitable treatment method is needed. This study supplemented the safety and time required of the potassium ferrocyanide method, which is the main material of clothing and can be applied to footwear impressions on cotton and polyester, for more efficient application. By changing the composition and application stage of the working solution under the reported potassium ferrocyanide method, the safety of the worker was ensured, and the reaction time required was shortened by applying heat. The degree of footwear impression enhancement of the improved technique showed a similar degree to the result of the existing technique, and the characteristics according to the surface were similar. The shape and pattern of the footwear, large substance, abrasion marks and damages could be observed. When applying the improved technique, the same level of results as the existing technique can be obtained. It is expected that the safety of workers and the time required can be shortened. Therefore, the improved technique in this study is proposed as a soil dust footwear impression enhancement technique on porous surface.
