The 10 fingerprints passive copy stored on the surface: neck glass bottle with a dust magnet (a) Adhesive Tex-Lift (b) and silicon crystal (c)
discuss findings from the image. 6 shows the average percentage of the main characteristics of latent fingerprints. Check collect on the surface uneven and curved surfaces with A powder magnetic method B glue Tex-Lift and C silicone clear to see that the use of silicone clear to sample tracks latent fingerprints that. a percentage point. An important characteristic of latent fingerprints than others. Because the properties of silicon crystal with a semi-liquid substance. Which can travel along the roughness of the surface uneven. You can keep peeling off A disc without using stick and peel tape storage as a way to use adhesive tape Tex-Lift requires help. Peel off the surface of the object from the works of Mill Morris reported that silicon crystal can be used. Check collect latent fingerprints on the surface. Horizontal surface And the surface in a straight line (Morris 2005) period, used to make silicone skin dry, depending on the thickness of the silicon crystal clear in this research have applied the clear hole to fit the tracks. latent fingerprint and then put a brace on the desired latent fingerprints collected before wiping with clear silicone. To get a thick sheet of silicone that has a latent fingerprint stick. In each instance, as well Not too thick For ease of identification comparison. Or can be used Spreader tip of Lynn Peavey Co., connected to the tube of the spray mixture automatically makes silicone flat beautiful flat width of about 1 inch (Frost 2005: 35) using adhesive Tex-Lift in the store. Latent fingerprints The quality of latent fingerprints on the floor. Textured fine But there are some problems on the outer surface of a door knob and glass bottleneck due to peeling the adhesive sheet can be thin and toughness, which is dark and may not be easy. In addition, the store on latent fingerprints. Surface also can not use transparent tape helps to remove the adhesive coating on latent fingerprints because the tape can not be curved along the surface of the object. Keep track of the Peel latent fingerprints on surfaces that are not flat horizontal surface, which can help to peel the tape collect latent fingerprints. So in store Latent fingerprints on the surface to be coated so that adhesive coated on latent fingerprints thicker than on the uneven surface which requires a period of time to allow the glue to dry up. Excess glue and some will trickle down. Making it difficult to keep a copy so that latent fingerprints rarely perfect. Which is based on expertise The samples were collected from the 9 and 10 tracks with latent fingerprints collected on the peeling surface. It is evident that the stripping latent fingerprints collected in a way that is similar lines, although Pictures 9 (a) and 10 (a) be a gap caused by the use of tape. Which makes the stripes are missing is ongoing. But a small part Possibly due to Latent fingerprints stamped onto the arches of the object of the research is intended to clear lines and curved surfaces such as glass and metal surfaces are smooth, non-porous. It's fingerprints. Latency is quite clear Only a little missing from time to time. But the scene could be found. Latent fingerprints only a small part. If latent fingerprints collected may not be sufficient latent fingerprints in identification. So it is a choice to use this new technique to store. Latent fingerprints get better
feedback 1. Chemicals used in this research to be ordered from abroad. You should look for chemicals. Like glue or silicone skin. With production, domestic sales came to trial. 2. To reduce the cost of storing latent fingerprints With this new technique requires training trained. To be Expertise to collect latent fingerprints. And should be willing to collect latent fingerprints because of latent fingerprints collected by this technique requires a detailed and intricately coupled with knowledge of the field. Science 3. Can be used to guide research in other types of surfaces. Latent fingerprints collected rare human skin. 4. bloody fingerprints can be used as a guide to choose how to collect latent fingerprints manipulated objects. Each witness To obtain latent fingerprints of good quality.
