The following magnetic fingerprint powders where used to conduct the R&D and produce this report together with the Forenscope Tablet installed with the IR and Colour Micro lenses. All enhancements of the images were done using the Forenscope Software.

  • Scenesafe Supranano Fluorescent Yellow Powder
  • Scenesafe Supranano Fluorescent Green Powder
  • Scenesafe Supranano Fluorescent Red Powder
  • Scenesafe Supranano Black Magnetic Powder

Conclusion:

The purpose of this document is not to score the quality of the visualised marks but to show that a variety of different powder colours matched with the power and versatility of the Forenscope Tablet can provide a solution to many different types of surface and background reflection. This document goes some way to clarifying the best match to specific documents with matching fingerprint powders, the light settings and software changes needed with the Forenscope Tablet to gain optimum imagery.
