This study investigated a selection of methods to detect latent fingermarks on black electrical tapes. Subsequently, a sequence of techniques was developed and is suggested as a standard operating procedure. Different formulations of white and silver powder suspensions were developed by comparing Citron detergent and Kodak Photo-Flo as the surfactant in the suspension. A mixture of both surfactants in the suspensions repeatedly produced greater fingerprint development on the adhesive side compared to using either one on its own. Two techniques consistently performed to a higher standard for both fresh and aged marks on the adhesive side: cyanoacrylate followed by a combined basic yellow 40/basic red 28 stain and the white powder suspension. The contrast, sharpness, ridge detail, and simplicity of preparation and application achieved with both of these techniques made them superior to the other methods tested. The sequence that proved successful on the adhesive side of all tapes tested involved cyanoacrylate fuming and application of a fluorescent stain, followed by white powder suspension, and finally gentian violet with a transfer of developed marks if necessary. This sequence allowed maximum development and the greatest enhancement of latent marks, without causing the destruction of the deposit for subsequent methods. Latent fingermarks on the backing (nonadhesive side) of the electrical tape were also successfully developed with cyanoacrylate and the fluorescent stain, so treatment of the backing could be incorporated into the sequence.

The use of a new technique, Fourier transform infrared (FTIR) chemical imaging, has been demonstrated for the enhancement of latent fingermarks on a number of surfaces. Images of untreated fingermarks on glass backgrounds with excellent ridge detail were acquired using infrared chemical imaging. High quality fingermarks on glass backgrounds were also developed using ethyl cyanoacrylate (super glue) fuming and subsequent infrared chemical imaging. This new method allows the collection of images from backgrounds that traditionally pose problems for current fingermark detection methods. The background may, for example, be highly colored, have a complex pattern, or possess other pattern or image characteristics that make it difficult to separate fingermark ridges using traditional optical or luminescent visualization. One background that has proven to be a challenging surface for the development of latent fingermarks is the Australian polymer banknote. To demonstrate the power and applicability of infrared chemical imaging, fingermarks fumed with ethyl cyanoacrylate were successfully imaged from Australian polymer banknotes.
