Abstract

The influence of humidification in the ESDA process on subsequent development of fingerprints on paper items was studied. It was found that, while the DFO process is nearly insensitive to previous humidification, fingerprint development with ninhydrin or with indanedione can be significantly affected by previous humidification of the paper.
