Impressions of friction ridges left on a surface are important evidence for identifying an individual and can be used to confirm his or her presence at the scene of an incident. Factors influencing the durability of fingerprints include the physiological characteristics and cleanliness of the individual, environmental factors, and time. The aim of the study was to determine the effect of atmospheric factors, gender, hand cleanliness and time on the width of friction ridge impressions and the amount of material forming the print. The research shows that factors such as gender, ambient conditions, and hand cleanliness affect the width of the ridge impressions and the quantity of material forming the print. The passage of time significantly reduces both the width of the ridge impressions and the quantity of the material forming the print.
